A low-level client representing Amazon EC2 Container Service (ECS)
Amazon Elastic Container Service (Amazon ECS) is a highly scalable, fast, container management service that makes it easy to run, stop, and manage Docker containers on a cluster. You can host your cluster on a serverless infrastructure that is managed by Amazon ECS by launching your services or tasks on Fargate. For more control, you can host your tasks on a cluster of Amazon Elastic Compute Cloud (Amazon EC2) instances that you manage.
Amazon ECS makes it easy to launch and stop container-based applications with simple API calls, allows you to get the state of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features.
You can use Amazon ECS to schedule the placement of containers across your cluster based on your resource needs, isolation policies, and availability requirements. Amazon ECS eliminates the need for you to operate your own cluster management and configuration management systems or worry about scaling your management infrastructure.

Creates a new capacity provider. Capacity providers are associated with an Amazon ECS cluster and are used in capacity provider strategies to facilitate cluster auto scaling.
Only capacity providers using an Auto Scaling group can be created. Amazon ECS tasks on Fargate use the FARGATE and FARGATE_SPOT capacity providers which are already created and available to all accounts in Regions supported by Fargate.

The Amazon Resource Name (ARN) that identifies the Auto Scaling group.
The managed scaling settings for the Auto Scaling group capacity provider.
Whether or not to enable managed scaling for the capacity provider.
The target capacity value for the capacity provider. The specified value must be greater than 0 and less than or equal to 100 . A value of 100 will result in the Amazon EC2 instances in your Auto Scaling group being completely utilized.
The minimum number of container instances that Amazon ECS will scale in or scale out at one time. If this parameter is omitted, the default value of 1 is used.
The maximum number of container instances that Amazon ECS will scale in or scale out at one time. If this parameter is omitted, the default value of 10000 is used.

The managed termination protection setting to use for the Auto Scaling group capacity provider. This determines whether the Auto Scaling group has managed termination protection.
Warning
When using managed termination protection, managed scaling must also be used otherwise managed termination protection will not work.
When managed termination protection is enabled, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions enabled as well. For more information, see Instance Protection in the Auto Scaling User Guide .
When managed termination protection is disabled, your Amazon EC2 instances are not protected from termination when the Auto Scaling group scales in.

Creates a new Amazon ECS cluster. By default, your account receives a default cluster when you launch your first container instance. However, you can create your own cluster with a unique name with the CreateCluster action.
Note
When you call the CreateCluster API operation, Amazon ECS attempts to create the Amazon ECS service-linked role for your account so that required resources in other Amazon Web Services services can be managed on your behalf. However, if the IAM user that makes the call does not have permissions to create the service-linked role, it is not created.

The short name of one or more capacity providers to associate with the cluster. A capacity provider must be associated with a cluster before it can be included as part of the default capacity provider strategy of the cluster or used in a capacity provider strategy when calling the CreateService or RunTask actions.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created and not already associated with another cluster. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.
The PutClusterCapacityProviders API operation is used to update the list of available capacity providers for a cluster after the cluster is created.
The capacity provider strategy to set as the default for the cluster. When a default capacity provider strategy is set for a cluster, when calling the RunTask or CreateService APIs wtih no capacity provider strategy or launch type specified, the default capacity provider strategy for the cluster is used.
If a default capacity provider strategy is not defined for a cluster during creation, it can be defined later with the PutClusterCapacityProviders API operation.
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
The short name of the capacity provider.
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

Runs and maintains a desired number of tasks from a specified task definition. If the number of tasks running in a service drops below the desiredCount , Amazon ECS runs another copy of the task in the specified cluster. To update an existing service, see the UpdateService action.
In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind one or more load balancers. The load balancers distribute traffic across the tasks that are associated with the service. For more information, see Service Load Balancing in the Amazon Elastic Container Service Developer Guide .
Tasks for services that do not use a load balancer are considered healthy if they're in the RUNNING state. Tasks for services that do use a load balancer are considered healthy if they're in the RUNNING state and the container instance that they're hosted on is reported as healthy by the load balancer.
There are two service scheduler strategies available:
You can optionally specify a deployment configuration for your service. The deployment is triggered by changing properties, such as the task definition or the desired count of a service, with an UpdateService operation. The default value for a replica service for minimumHealthyPercent is 100%. The default value for a daemon service for minimumHealthyPercent is 0%.
If a service is using the ECS deployment controller, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in the RUNNING state during a deployment, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler might stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they're in the RUNNING state. Tasks for services that do use a load balancer are considered healthy if they're in the RUNNING state and they're reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the ECS deployment controller, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.
If a service is using either the CODE_DEPLOY or EXTERNAL deployment controller types and tasks that use the EC2 launch type, the minimum healthy percent and maximum percent values are used only to define the lower and upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the minimum healthy percent and maximum percent values aren't used, although they're currently visible when describing your service.
When creating a service that uses the EXTERNAL deployment controller, you can specify only parameters that aren't controlled at the task set level. The only required parameter is the service name. You control your services using the CreateTaskSet operation. For more information, see Amazon ECS Deployment Types in the Amazon Elastic Container Service Developer Guide .
When the service scheduler launches new tasks, it determines task placement in your cluster using the following logic:

The family and revision (family:revision ) or full ARN of the task definition to run in your service. If a revision is not specified, the latest ACTIVE revision is used.
A task definition must be specified if the service is using either the ECS or CODE_DEPLOY deployment controllers.
A load balancer object representing the load balancers to use with your service. For more information, see Service Load Balancing in the Amazon Elastic Container Service Developer Guide .
If the service is using the rolling update (ECS ) deployment controller and using either an Application Load Balancer or Network Load Balancer, you must specify one or more target group ARNs to attach to the service. The service-linked role is required for services that make use of multiple target groups. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide .
If the service is using the CODE_DEPLOY deployment controller, the service is required to use either an Application Load Balancer or Network Load Balancer. When creating an CodeDeploy deployment group, you specify two target groups (referred to as a targetGroupPair ). During a deployment, CodeDeploy determines which task set in your service has the status PRIMARY and associates one target group with it, and then associates the other target group with the replacement task set. The load balancer can also have up to two listeners: a required listener for production traffic and an optional listener that allows you perform validation tests with Lambda functions before routing production traffic to it.
After you create a service using the ECS deployment controller, the load balancer name or target group ARN, container name, and container port specified in the service definition are immutable. If you are using the CODE_DEPLOY deployment controller, these values can be changed when updating the service.
For Application Load Balancers and Network Load Balancers, this object must contain the load balancer target group ARN, the container name (as it appears in a container definition), and the container port to access from the load balancer. The load balancer name parameter must be omitted. When a task from this service is placed on a container instance, the container instance and port combination is registered as a target in the target group specified here.
For Classic Load Balancers, this object must contain the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer. The target group ARN parameter must be omitted. When a task from this service is placed on a container instance, the container instance is registered with the load balancer specified here.
Services with tasks that use the awsvpc network mode (for example, those with the Fargate launch type) only support Application Load Balancers and Network Load Balancers. Classic Load Balancers are not supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance , because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
The load balancer configuration to use with a service or task set.
For specific notes and restrictions regarding the use of load balancers with services and task sets, see the CreateService and CreateTaskSet actions.
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
The name of the container (as it appears in a container definition) to associate with the load balancer.
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they are launched on must allow ingress traffic on the hostPort of the port mapping.
The details of the service discovery registry to associate with this service. For more information, see Service discovery .
Note
Each service may be associated with one service registry. Multiple service registries per service isn't supported.
Details of the service registry.
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .
The port value used if your service discovery service specified an SRV record. This field may be used if both the awsvpc network mode and SRV records are used.
The container name value, already specified in the task definition, to be used for your service discovery service. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
The port value, already specified in the task definition, to be used for your service discovery service. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
The number of instantiations of the specified task definition to place and keep running on your cluster.
This is required if schedulingStrategy is REPLICA or is not specified. If schedulingStrategy is DAEMON then this is not required.
The infrastructure on which to run your service. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
The FARGATE launch type runs your tasks on Fargate On-Demand infrastructure.
Note
Fargate Spot infrastructure is available for use but a capacity provider strategy must be used. For more information, see Fargate capacity providers in the Amazon ECS User Guide for Fargate .
The EC2 launch type runs your tasks on Amazon EC2 instances registered to your cluster.
The EXTERNAL launch type runs your tasks on your on-premise server or virtual machine (VM) capacity registered to your cluster.
A service can use either a launch type or a capacity provider strategy. If a launchType is specified, the capacityProviderStrategy parameter must be omitted.
The capacity provider strategy to use for the service.
If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
The short name of the capacity provider.
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
The name or full Amazon Resource Name (ARN) of the IAM role that allows Amazon ECS to make calls to your load balancer on your behalf. This parameter is only permitted if you are using a load balancer with your service and your task definition does not use the awsvpc network mode. If you specify the role parameter, you must also specify a load balancer object with the loadBalancers parameter.
Warning
If your account has already created the Amazon ECS service-linked role, that role is used by default for your service unless you specify a role here. The service-linked role is required if your task definition uses the awsvpc network mode or if the service is configured to use service discovery, an external deployment controller, multiple target groups, or Elastic Inference accelerators in which case you should not specify a role here. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide .
If your specified role has a path other than / , then you must either specify the full role ARN (this is recommended) or prefix the role name with the path. For example, if a role with the name bar has a path of /foo/ then you would specify /foo/bar as the role name. For more information, see Friendly names and paths in the IAM User Guide .
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
Note
The deployment circuit breaker can only be used for services using the rolling update (ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If deployment circuit breaker is enabled, a service deployment will transition to a failed state and stop launching new tasks. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
Whether to enable the deployment circuit breaker logic for the service.
Whether to enable Amazon ECS to roll back the service if a service deployment fails. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
If a service is using the rolling update (ECS ) deployment type, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
If a service is using the rolling update (ECS ) deployment type, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in the RUNNING state during a deployment, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.
An array of placement constraint objects to use for tasks in your service. You can specify a maximum of 10 constraints per task (this limit includes constraints in the task definition and those specified at runtime).
An object representing a constraint on task placement. For more information, see Task Placement Constraints in the Amazon Elastic Container Service Developer Guide .
Note
If you are using the Fargate launch type, task placement constraints are not supported.
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is distinctInstance . For more information, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide .
The placement strategy objects to use for tasks in your service. You can specify a maximum of five strategy rules per service.
The task placement strategy for a task or service. For more information, see Task Placement Strategies in the Amazon Elastic Container Service Developer Guide .
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that is specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory (but still enough to run the task).
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
The network configuration for the service. This parameter is required for task definitions that use the awsvpc network mode to receive their own elastic network interface, and it is not supported for other network modes. For more information, see Task networking in the Amazon Elastic Container Service Developer Guide .
The VPC subnets and security groups associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
The IDs of the subnets associated with the task or service. There is a limit of 16 subnets that can be specified per AwsVpcConfiguration .
Note
All specified subnets must be from the same VPC.
The IDs of the security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
The period of time, in seconds, that the Amazon ECS service scheduler should ignore unhealthy Elastic Load Balancing target health checks after a task has first started. This is only used when your service is configured to use a load balancer. If your service has a load balancer defined and you don't specify a health check grace period value, the default value of 0 is used.
If your service's tasks take a while to start and respond to Elastic Load Balancing health checks, you can specify a health check grace period of up to 2,147,483,647 seconds. During that time, the Amazon ECS service scheduler ignores health check status. This grace period can prevent the service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.
The scheduling strategy to use for the service. For more information, see Services .
There are two service scheduler strategies available:
Note
Tasks using the Fargate launch type or the CODE_DEPLOY or EXTERNAL deployment controller types don't support the DAEMON scheduling strategy.
The deployment controller to use for the service. If no deployment controller is specified, the default value of ECS is used.
The deployment controller type to use.
There are three deployment controller types available:
ECS
The rolling update (ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration .
CODE_DEPLOY
The blue/green (CODE_DEPLOY ) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.
EXTERNAL
The external (EXTERNAL ) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.
The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. When a service is deleted, the tags are deleted as well.
The following basic restrictions apply to tags:
The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

service (dict) --
The full description of your service following the create call.
A service will return either a capacityProviderStrategy or launchType parameter, but not both, depending on which one was specified during creation.
If a service is using the ECS deployment controller, the deploymentController and taskSets parameters will not be returned.
If the service is using the CODE_DEPLOY deployment controller, the deploymentController , taskSets and deployments parameters will be returned, however the deployments parameter will be an empty list.
serviceArn (string) --
The ARN that identifies the service. The ARN contains the arn:aws:ecs namespace, followed by the Region of the service, the account ID of the service owner, the service namespace, and then the service name. For example, arn:aws:ecs:region:012345678910:service/my-service .
serviceName (string) --
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.

For specific notes and restrictions regarding the use of load balancers with services and task sets, see the CreateService and CreateTaskSet actions.
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they are launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details of the service discovery registries to assign to this service. For more information, see Service Discovery .
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .
port (integer) --
The port value used if your service discovery service specified an SRV record. This field may be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
status (string) --
The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .
desiredCount (integer) --
The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .

The number of tasks in the cluster that are in the RUNNING state.
pendingCount (integer) --
The number of tasks in the cluster that are in the PENDING state.
launchType (string) --
The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.
capacityProviderStrategy (list) --
The capacity provider strategy the service is using. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --
The platform version on which to run your service. A platform version is only specified for tasks hosted on Fargate. If one is not specified, the LATEST platform version is used by default. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
taskDefinition (string) --
The task definition to use for tasks in the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .
deploymentConfiguration (dict) --
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker (dict) --
Note
The deployment circuit breaker can only be used for services using the rolling update (ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If deployment circuit breaker is enabled, a service deployment will transition to a failed state and stop launching new tasks. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
enable (boolean) --
Whether to enable the deployment circuit breaker logic for the service.
rollback (boolean) --
Whether to enable Amazon ECS to roll back the service if a service deployment fails. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent (integer) --
If a service is using the rolling update (ECS ) deployment type, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimumHealthyPercent (integer) --
If a service is using the rolling update (ECS ) deployment type, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in the RUNNING state during a deployment, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.
taskSets (list) --
Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.
(dict) --
Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.
id (string) --
The ID of the task set.
taskSetArn (string) --
The Amazon Resource Name (ARN) of the task set.
serviceArn (string) --
The Amazon Resource Name (ARN) of the service the task set exists in.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that the service that hosts the task set exists in.
startedBy (string) --
The tag specified when a task set is started. If the task set is created by an CodeDeploy deployment, the startedBy parameter is CODE_DEPLOY . For a task set created for an external deployment, the startedBy field isn't used.
externalId (string) --
The external ID associated with the task set.
If a task set is created by an CodeDeploy deployment, the externalId parameter contains the CodeDeploy deployment ID.
If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.
status (string) --
The status of the task set. The following describes each state:
PRIMARY
The task set is serving production traffic.
ACTIVE
The task set is not serving production traffic.
DRAINING
The tasks in the task set are being stopped and their corresponding targets are being deregistered from their target group.
taskDefinition (string) --
The task definition the task set is using.
computedDesiredCount (integer) --
The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.
pendingCount (integer) --
The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it is restarted after being in the STOPPED state.
runningCount (integer) --
The number of tasks in the task set that are in the RUNNING status during a deployment. A task in the RUNNING state is running and ready for use.
createdAt (datetime) --
The Unix timestamp for when the task set was created.
updatedAt (datetime) --
The Unix timestamp for when the task set was last updated.
launchType (string) --
The launch type the tasks in the task set are using. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
capacityProviderStrategy (list) --
The capacity provider strategy associated with the task set.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --
The Fargate platform version on which the tasks in the task set are running. A platform version is only specified for tasks run on Fargate. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide .

awsvpcConfiguration (dict) --
The VPC subnets and security groups associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
subnets (list) --
The IDs of the subnets associated with the task or service. There is a limit of 16 subnets that can be specified per AwsVpcConfiguration .
Note
All specified subnets must be from the same VPC.
securityGroups (list) --
The IDs of the security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
loadBalancers (list) --
Details on a load balancer that is used with a task set.
(dict) --

targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they are launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details of the service discovery registries to assign to this task set. For more information, see Service discovery .
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .

containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
scale (dict) --
A floating-point percentage of the desired number of tasks to place and keep running in the task set.
value (float) --
The value, specified as a percent total of a service's desiredCount , to scale the task set. Accepted values are numbers between 0 and 100.

runningCount (integer) --
The number of tasks in the deployment that are in the RUNNING status.
failedTasks (integer) --
The number of consecutively failed tasks in the deployment. A task is considered a failure if the service scheduler can't launch the task, the task doesn't transition to a RUNNING state, or if it fails any of its defined health checks and is stopped.
Note
Once a service deployment has one or more successfully running tasks, the failed task count resets to zero and stops being evaluated.
createdAt (datetime) --
The Unix timestamp for when the service deployment was created.
updatedAt (datetime) --
The Unix timestamp for when the service deployment was last updated.
capacityProviderStrategy (list) --
The capacity provider strategy that the deployment is using.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
rolloutState (string) --
Note
The rolloutState of a service is only returned for services that use the rolling update (ECS ) deployment type that are not behind a Classic Load Balancer.
The rollout state of the deployment. When a service deployment is started, it begins in an IN_PROGRESS state. When the service reaches a steady state, the deployment will transition to a COMPLETED state. If the service fails to reach a steady state and circuit breaker is enabled, the deployment will transition to a FAILED state. A deployment in FAILED state will launch no new tasks. For more information, see DeploymentCircuitBreaker .

(dict) --
The task placement strategy for a task or service. For more information, see Task Placement Strategies in the Amazon Elastic Container Service Developer Guide .
type (string) --
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that is specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory (but still enough to run the task).
field (string) --
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.

type (string) --
The deployment controller type to use.
There are three deployment controller types available:
ECS
The rolling update (ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration .

Note
All specified subnets and security groups must be from the same VPC.
The IDs of the subnets associated with the task or service. There is a limit of 16 subnets that can be specified per AwsVpcConfiguration .
Note
All specified subnets must be from the same VPC.
The IDs of the security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
A load balancer object representing the load balancer to use with the task set. The supported load balancer types are either an Application Load Balancer or a Network Load Balancer.
The load balancer configuration to use with a service or task set.
For specific notes and restrictions regarding the use of load balancers with services and task sets, see the CreateService and CreateTaskSet actions.
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
The name of the container (as it appears in a container definition) to associate with the load balancer.
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they are launched on must allow ingress traffic on the hostPort of the port mapping.
The details of the service discovery registries to assign to this task set. For more information, see Service Discovery .
Details of the service registry.
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .

The launch type that new tasks in the task set will use. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide .
If a launchType is specified, the capacityProviderStrategy parameter must be omitted.
The capacity provider strategy to use for the task set.
A capacity provider strategy consists of one or more capacity providers along with the base and weight to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with an ACTIVE or UPDATING status can be used.
If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.
The PutClusterCapacityProviders API operation is used to update the list of available capacity providers for a cluster after the cluster is created.
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
The short name of the capacity provider.
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
A floating-point percentage of the desired number of tasks to place and keep running in the task set.
The value, specified as a percent total of a service's desiredCount , to scale the task set. Accepted values are numbers between 0 and 100.
The unit of measure for the scale value.
The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. When a service is deleted, the tags are deleted as well.
The following basic restrictions apply to tags:

Exceptions
Deletes the specified capacity provider.
Note
The FARGATE and FARGATE_SPOT capacity providers are reserved and cannot be deleted. You can disassociate them from a cluster using either the PutClusterCapacityProviders API or by deleting the cluster.
Prior to a capacity provider being deleted, the capacity provider must be removed from the capacity provider strategy from all services. The UpdateService API can be used to remove a capacity provider from a service's capacity provider strategy. When updating a service, the forceNewDeployment option can be used to ensure that any tasks using the Amazon EC2 instance capacity provided by the capacity provider are transitioned to use the capacity from the remaining capacity providers. Only capacity providers that are not associated with a cluster can be deleted. To remove a capacity provider from a cluster, you can either use PutClusterCapacityProviders or delete the cluster.

The Amazon Resource Name (ARN) that identifies the Auto Scaling group.
The managed scaling settings for the Auto Scaling group capacity provider.
Whether or not to enable managed scaling for the capacity provider.
The target capacity value for the capacity provider. The specified value must be greater than 0 and less than or equal to 100 . A value of 100 will result in the Amazon EC2 instances in your Auto Scaling group being completely utilized.
The minimum number of container instances that Amazon ECS will scale in or scale out at one time. If this parameter is omitted, the default value of 1 is used.
The maximum number of container instances that Amazon ECS will scale in or scale out at one time. If this parameter is omitted, the default value of 10000 is used.
The period of time, in seconds, after a newly launched Amazon EC2 instance can contribute to CloudWatch metrics for Auto Scaling group. If this parameter is omitted, the default value of 300 seconds is used.
The managed termination protection setting to use for the Auto Scaling group capacity provider. This determines whether the Auto Scaling group has managed termination protection.
Warning
When using managed termination protection, managed scaling must also be used otherwise managed termination protection will not work.
When managed termination protection is enabled, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions enabled as well. For more information, see Instance Protection in the Auto Scaling User Guide .
When managed termination protection is disabled, your Amazon EC2 instances are not protected from termination when the Auto Scaling group scales in.
The update status of the capacity provider. The following are the possible states that will be returned.
DELETE_IN_PROGRESS
The capacity provider is in the process of being deleted.
DELETE_COMPLETE
The capacity provider has been successfully deleted and will have an INACTIVE status.

The status of the cluster. The following are the possible states that will be returned.
ACTIVE
The cluster is ready to accept tasks and if applicable you can register container instances with the cluster.
PROVISIONING
The cluster has capacity providers associated with it and the resources needed for the capacity provider are being created.
DEPROVISIONING
The cluster has capacity providers associated with it and the resources needed for the capacity provider are being deleted.
FAILED
The cluster has capacity providers associated with it and the resources needed for the capacity provider have failed to create.
INACTIVE
The cluster has been deleted. Clusters with an INACTIVE status may remain discoverable in your account for a period of time. However, this behavior is subject to change in the future, so you should not rely on INACTIVE clusters persisting.
The number of container instances registered into the cluster. This includes container instances in both ACTIVE and DRAINING status.
The number of tasks in the cluster that are in the RUNNING state.
The number of tasks in the cluster that are in the PENDING state.
The number of services that are running on the cluster in an ACTIVE state. You can view these services with ListServices .
Additional information about your clusters that are separated by launch type, including:
A key-value pair object.
The name of the key-value pair. For environment variables, this is the name of the environment variable.
The value of the key-value pair. For environment variables, this is the value of the environment variable.
The metadata that you apply to the cluster to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
The settings for the cluster. This parameter indicates whether CloudWatch Container Insights is enabled or disabled for a cluster.
The settings to use when creating a cluster. This parameter is used to enable CloudWatch Container Insights for a cluster.
The name of the cluster setting. The only supported value is containerInsights .
The value to set for the cluster setting. The supported values are enabled and disabled . If enabled is specified, CloudWatch Container Insights will be enabled for the cluster, otherwise it will be disabled unless the containerInsights account setting is enabled. If a cluster value is specified, it will override the containerInsights value set with PutAccountSetting or PutAccountSettingDefault .
The capacity providers associated with the cluster.
The default capacity provider strategy for the cluster. When services or tasks are run in the cluster with no launch type or capacity provider strategy specified, the default capacity provider strategy is used.
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
The short name of the capacity provider.
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
The resources attached to a cluster. When using a capacity provider with a cluster, the Auto Scaling plan that is created will be returned as a cluster attachment.
An object representing a container instance or task attachment.
The unique identifier for the attachment.
The type of the attachment, such as ElasticNetworkInterface .
The status of the attachment. Valid values are PRECREATED , CREATED , ATTACHING , ATTACHED , DETACHING , DETACHED , and DELETED .
Details of the attachment. For elastic network interfaces, this includes the network interface ID, the MAC address, the subnet ID, and the private IPv4 address.
A key-value pair object.
The name of the key-value pair. For environment variables, this is the name of the environment variable.
The value of the key-value pair. For environment variables, this is the value of the environment variable.
The status of the capacity providers associated with the cluster. The following are the states that will be returned:
UPDATE_IN_PROGRESS
The available capacity providers for the cluster are updating. This occurs when the Auto Scaling plan is provisioning or deprovisioning.
UPDATE_COMPLETE
The capacity providers have successfully updated.
UPDATE_FAILED
The capacity provider updates failed.
Exceptions
Examples
This example deletes an empty cluster in your default region.

Deletes a specified service within a cluster. You can delete a service if you have no running tasks in it and the desired task count is zero. If the service is actively maintaining tasks, you cannot delete it, and you must update the service to a desired task count of zero. For more information, see UpdateService .
Note
When you delete a service, if there are still running tasks that require cleanup, the service status moves from ACTIVE to DRAINING , and the service is no longer visible in the console or in the ListServices API operation. After all tasks have transitioned to either STOPPING or STOPPED status, the service status moves from DRAINING to INACTIVE . Services in the DRAINING or INACTIVE status can still be viewed with the DescribeServices API operation. However, in the future, INACTIVE services may be cleaned up and purged from Amazon ECS record keeping, and DescribeServices calls on those services return a ServiceNotFoundException error.
Warning
If you attempt to create a new service with the same name as an existing service in either ACTIVE or DRAINING status, you receive an error.

serviceName (string) --
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that hosts the service.
loadBalancers (list) --
A list of Elastic Load Balancing load balancer objects, containing the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer.
(dict) --
The load balancer configuration to use with a service or task set.
For specific notes and restrictions regarding the use of load balancers with services and task sets, see the CreateService and CreateTaskSet actions.
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they are launched on must allow ingress traffic on the hostPort of the port mapping.

The container name value, already specified in the task definition, to be used for your service discovery service. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
status (string) --
The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .
desiredCount (integer) --
The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .

The number of tasks in the cluster that are in the PENDING state.
launchType (string) --
The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.
capacityProviderStrategy (list) --
The capacity provider strategy the service is using. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --
The platform version on which to run your service. A platform version is only specified for tasks hosted on Fargate. If one is not specified, the LATEST platform version is used by default. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
taskDefinition (string) --
The task definition to use for tasks in the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .
deploymentConfiguration (dict) --
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker (dict) --
Note
The deployment circuit breaker can only be used for services using the rolling update (ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If deployment circuit breaker is enabled, a service deployment will transition to a failed state and stop launching new tasks. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
enable (boolean) --
Whether to enable the deployment circuit breaker logic for the service.
rollback (boolean) --
Whether to enable Amazon ECS to roll back the service if a service deployment fails. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent (integer) --
If a service is using the rolling update (ECS ) deployment type, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimumHealthyPercent (integer) --
If a service is using the rolling update (ECS ) deployment type, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in the RUNNING state during a deployment, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

If a task set is created by an CodeDeploy deployment, the externalId parameter contains the CodeDeploy deployment ID.
If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.
status (string) --
The status of the task set. The following describes each state:

For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

(dict) --
The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
deployments (list) --
The current state of deployments for the service.
(dict) --
The details of an Amazon ECS service deployment. This is used only when a service uses the ECS deployment controller type.
id (string) --
The ID of the deployment.
status (string) --
The status of the deployment. The following describes each state:
PRIMARY
The most recent deployment of a service.
ACTIVE
A service deployment that still has running tasks, but are in the process of being replaced with a new PRIMARY deployment.
INACTIVE
A deployment that has been completely replaced.
taskDefinition (string) --
The most recent task definition that was specified for the tasks in the service to use.
desiredCount (integer) --
The most recent desired count of tasks that was specified for the service to deploy or maintain.

The number of tasks in the deployment that are in the PENDING status.
runningCount (integer) --
The number of tasks in the deployment that are in the RUNNING status.
failedTasks (integer) --
The number of consecutively failed tasks in the deployment. A task is considered a failure if the service scheduler can't launch the task, the task doesn't transition to a RUNNING state, or if it fails any of its defined health checks and is stopped.
Note
Once a service deployment has one or more successfully running tasks, the failed task count resets to zero and stops being evaluated.
createdAt (datetime) --
The Unix timestamp for when the service deployment was created.
updatedAt (datetime) --
The Unix timestamp for when the service deployment was last updated.
capacityProviderStrategy (list) --
The capacity provider strategy that the deployment is using.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

The launch type the tasks in the service are using. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide .
platformVersion (string) --
The platform version on which your tasks in the service are running. A platform version is only specified for tasks using the Fargate launch type. If one is not specified, the LATEST platform version is used by default. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
networkConfiguration (dict) --
The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.
awsvpcConfiguration (dict) --
The VPC subnets and security groups associated with a task.
Note
All specified subnets and security groups must be from the same VPC.

Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
rolloutState (string) --
Note
The rolloutState of a service is only returned for services that use the rolling update (ECS ) deployment type that are not behind a Classic Load Balancer.
The rollout state of the deployment. When a service deployment is started, it begins in an IN_PROGRESS state. When the service reaches a steady state, the deployment will transition to a COMPLETED state. If the service fails to reach a steady state and circuit breaker is enabled, the deployment will transition to a FAILED state. A deployment in FAILED state will launch no new tasks. For more information, see DeploymentCircuitBreaker .
rolloutStateReason (string) --
A description of the rollout state of a deployment.
roleArn (string) --
The ARN of the IAM role associated with the service that allows the Amazon ECS container agent to register container instances with an Elastic Load Balancing load balancer.

message (string) --
The event message.
createdAt (datetime) --
The Unix timestamp for when the service was created.
placementConstraints (list) --
The placement constraints for the tasks in the service.
(dict) --
An object representing a constraint on task placement. For more information, see Task Placement Constraints in the Amazon Elastic Container Service Developer Guide .
Note
If you are using the Fargate launch type, task placement constraints are not supported.
type (string) --
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
expression (string) --
A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is distinctInstance . For more information, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide .

(dict) --
The task placement strategy for a task or service. For more information, see Task Placement Strategies in the Amazon Elastic Container Service Developer Guide .
type (string) --
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that is specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory (but still enough to run the task).
field (string) --
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone .

Note
All specified subnets must be from the same VPC.
securityGroups (list) --
The IDs of the security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups that can be specified per AwsVpcConfiguration .

The deployment controller type the service is using. When using the DescribeServices API, this field is omitted if the service is using the ECS deployment controller type.
type (string) --
The deployment controller type to use.
There are three deployment controller types available:
ECS
The rolling update (ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration .
CODE_DEPLOY
The blue/green (CODE_DEPLOY ) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.
EXTERNAL
The external (EXTERNAL ) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.

Exceptions
Deregisters an Amazon ECS container instance from the specified cluster. This instance is no longer available to run tasks.
If you intend to use the container instance for some other purpose after deregistration, you should stop all of the tasks running on the container instance before deregistration. That prevents any orphaned tasks from consuming resources.
Deregistering a container instance removes the instance from a cluster, but it does not terminate the EC2 instance. If you are finished using the instance, be sure to terminate it in the Amazon EC2 console to stop billing.
Note
If you terminate a running container instance, Amazon ECS automatically deregisters the instance from your cluster (stopped container instances or instances with disconnected agents are not automatically deregistered when terminated).

Request Syntax
response = client.deregister_container_instance(
cluster='string',
containerInstance='string',
force=True|False
)
[REQUIRED]
The container instance ID or full ARN of the container instance to deregister. The ARN contains the arn:aws:ecs namespace, followed by the Region of the container instance, the account ID of the container instance owner, the container-instance namespace, and then the container instance ID. For example, arn:aws:ecs:region:aws_account_id:container-instance/container_instance_ID .
Forces the deregistration of the container instance. If you have tasks running on the container instance when you deregister it with the force option, these tasks remain running until you terminate the instance or the tasks stop through some other means, but they are orphaned (no longer monitored or accounted for by Amazon ECS). If an orphaned task on your container instance is part of an Amazon ECS service, then the service scheduler starts another copy of that task, on a different container instance if possible.
Any containers in orphaned service tasks that are registered with a Classic Load Balancer or an Application Load Balancer target group are deregistered. They begin connection draining according to the settings on the load balancer or target group.

status (string) --
The status of the container instance. The valid values are REGISTERING , REGISTRATION_FAILED , ACTIVE , INACTIVE , DEREGISTERING , or DRAINING .
If your account has opted in to the awsvpcTrunking account setting, then any newly registered container instance will transition to a REGISTERING status while the trunk elastic network interface is provisioned for the instance. If the registration fails, the instance will transition to a REGISTRATION_FAILED status. You can describe the container instance and see the reason for failure in the statusReason parameter. Once the container instance is terminated, the instance transitions to a DEREGISTERING status while the trunk elastic network interface is deprovisioned. The instance then transitions to an INACTIVE status.
The ACTIVE status indicates that the container instance can accept tasks. The DRAINING indicates that new tasks are not placed on the container instance and any service tasks running on the container instance are removed if possible. For more information, see Container Instance Draining in the Amazon Elastic Container Service Developer Guide .

(dict) --
The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
Exceptions
Examples
This example deregisters a container instance from the specified cluster in your default region. If there are still tasks running on the container instance, you must either stop those tasks before deregistering, or use the force option.
response = client.deregister_container_instance(
cluster='default',
containerInstance='container_instance_UUID',
force=True,
)
print(response)
Expected Output:
{
'ResponseMetadata': {
'...': '...',
},
}
Deregisters the specified task definition by family and revision. Upon deregistration, the task definition is marked as INACTIVE . Existing tasks and services that reference an INACTIVE task definition continue to run without disruption. Existing services that reference an INACTIVE task definition can still scale up or down by modifying the service's desired count.
You cannot use an INACTIVE task definition to run new tasks or create new services, and you cannot update an existing service to reference an INACTIVE task definition. However, there may be up to a 10-minute window following deregistration where these restrictions have not yet taken effect.
Note
At this time, INACTIVE task definitions remain discoverable in your account indefinitely. However, this behavior is subject to change in the future, so you should not rely on INACTIVE task definitions persisting beyond the lifecycle of any associated tasks and services.

Response Structure
The full description of the deregistered task.
The full Amazon Resource Name (ARN) of the task definition.
A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide .
Container definitions are used in task definitions to describe the different containers that are launched as part of a task.
The name of a container. If you are linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run .
The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with either `` repository-url /image :tag `` or `` repository-url /image @*digest* `` . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run .
The private repository authentication credentials to use.
The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note
When you are using the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you are launching then you can use either the full ARN or the name of the secret. When you are using the Amazon Web Services Management Console, you must specify the full ARN of the secret.
The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run .
This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.
Note
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that is the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that is described in the task definition. A null or zero CPU value is passed to Docker as 0 , which Windows interprets as 1% of one CPU.
The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run .
If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance on which the container is placed. Otherwise, the value of memory is used.
The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.
The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run .
If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance on which the container is placed. Otherwise, the value of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.
The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.
The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge . The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run .
Note
This parameter is not supported for Windows containers.
Warning
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the awsvpc network mode, you should only specify the containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Port mappings on Windows use the NetNAT gateway address rather than localhost . There is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself.
This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run . If the network mode of a task definition is set to none , then you can't specify port mappings. If the network mode of a task definition is set to host , then host ports must either be undefined or they must match the container port in the port mapping.
Note
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.
If you are using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Note
You cannot expose the same container port for multiple protocols. An error will be returned if this is attempted
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.
The port number on the container that is bound to the user-specified or automatically assigned host port.
If you are using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort .
If you are using containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort . Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.
The port number on the container instance to reserve for your container.
If you are using containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort .
If you are using containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0 ) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.
The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range . If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.
Note
The default ephemeral port range from 49153 through 65535 is always used for Docker versions before 1.6.0.
The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running (after a task stops, the host port is released). The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time, including the default reserved ports. Automatically assigned ports don't count toward the 100 reserved ports limit.
The protocol used for the port mapping. Valid values are tcp and udp . The default is tcp .
If the essential parameter of a container is marked as true , and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false , then its failure does not affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that is composed of multiple containers, you should group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide .
Warning
Early versions of the Amazon ECS container agent do not properly handle entryPoint parameters. If you have problems using entryPoint , update your container agent or enter your commands and arguments as command array items instead.
The entry point that is passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run . For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint .
The command that is passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run . For more information, see https://docs.docker.com/engine/reference/builder/#cmd . If there are multiple arguments, each argument should be a separated string in the array.
The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run .
Warning
We do not recommend using plaintext environment variables for sensitive information, such as credential data.
A key-value pair object.
The name of the key-value pair. For environment variables, this is the name of the environment variable.
The value of the key-value pair. For environment variables, this is the value of the environment variable.
A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run .
You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file should contain an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored. For more information on the environment variable file syntax, see Declare default environment variables in file .
If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they are processed from the top down. It is recommended to use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide .

The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.
If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
If you are using tasks that use the Fargate launch type, the maxSwap parameter is not supported.
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run .

However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
For tasks using the Fargate launch type, the task or service requires platform version 1.3.0 or later.
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
Your Amazon ECS container instances require at least version 1.26.0 of the container agent to enable container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package.

For tasks using the Fargate launch type, this parameter requires that the task or service uses platform version 1.3.0 or later.
The name of a container.
The dependency condition of the container. The following are the available conditions and their behavior:
Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE , SUCCESS , or HEALTHY status. If a startTimeout value is specified for containerB and it does not reach the desired status within that time then containerA will give up and not start. This results in the task transitioning to a STOPPED state.
Note
When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it is enforced indendently from this start timeout value.
For tasks using the Fargate launch type, this parameter requires that the task or service uses platform version 1.3.0 or later.
For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to enable a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires platform version 1.3.0 or later. The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks using the EC2 launch type, if the stopTimeout parameter is not specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used by default. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to enable a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init .

To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it will override the default values set by Docker. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run . Valid naming values are displayed in the Ulimit data type.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and hard limit is 4096 .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
This parameter is not supported for Windows containers.
The ulimit settings to pass to the container.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and hard limit is 4096 .
The type of the ulimit .
The soft limit for the ulimit type.
The hard limit for the ulimit type.
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run . By default, containers use the same logging driver that the Docker daemon uses. However the container may use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries ,``syslog`` , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that is not listed, you can fork the Amazon ECS container agent project that is available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we do not currently provide support for running modified copies of this software.
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
The secrets to pass to the log configuration. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
The name of the secret.
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
Note
If the SSM Parameter Store parameter exists in the same Region as the task you are launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run .
A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to execute the command arguments directly, or CMD-SHELL to run the command with the container's default shell. For example:
[ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]
An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in the Create a container section of the Docker Remote API .
The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.
The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.
The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.
The optional grace period within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You may specify between 0 and 300 seconds. The startPeriod is disabled by default.
Note
If a health check succeeds within the startPeriod , then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run .
Note
It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. For tasks that use the awsvpc network mode, the container that is started last determines which systemControls parameters take effect. For tasks that use the host network mode, it changes the container instance's namespaced kernel parameters as well as the containers.
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run .
It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network mode for the following reasons:
The namespaced kernel parameter for which to set a value .
The value for the namespaced kernel parameter specified in namespace .
The type and amount of a resource to assign to a container. The only supported resource is a GPU.
The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see Working with GPUs on Amazon ECS or Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide
The value for the specified resource type.
If the GPU type is used, the value is the number of physical GPUs the Amazon ECS container agent will reserve for the container. The number of GPUs reserved for all containers in a task should not exceed the number of available GPUs on the container instance the task is launched on.
If the InferenceAccelerator type is used, the value should match the deviceName for an InferenceAccelerator specified in a task definition.
The type of resource to assign to a container. The supported values are GPU or InferenceAccelerator .
The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide .
The log router to use. The valid values are fluentd or fluentbit .
The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"} . For more information, see Creating a Task Definition that Uses a FireLens Configuration in the Amazon Elastic Container Service Developer Guide .
Note
Tasks hosted on Fargate only support the file configuration file type.
The name of a family that this task definition is registered to. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide .
IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code in order to take advantage of the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide .
The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide .
The Docker networking mode to use for the containers in the task. The valid values are none , bridge , awsvpc , and host . If no network mode is specified, the default is bridge .
For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none , you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.
With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.
Warning
When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.
If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .
If the network mode is host , you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.
For more information, see Network settings in the Docker run reference .
The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is 1 . Each time that you register a new revision of a task definition in the same family, the revision value always increases by one, even if you have deregistered previous revisions in this family.
The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide .
Note
The host and sourcePath parameters are not supported for tasks run on Fargate.
A data volume used in a task definition. For tasks that use the Amazon Elastic File System (Amazon EFS), specify an efsVolumeConfiguration . For Windows tasks that use Amazon FSx for Windows File Server file system, specify a fsxWindowsFileServerVolumeConfiguration . For tasks that use a Docker volume, specify a DockerVolumeConfiguration . For tasks that use a bind mount host volume, specify a host and optional sourcePath . For more information, see Using Data Volumes in Tasks .
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints .
This parameter is specified when you are using bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data is not guaranteed to persist after the containers associated with it stop running.
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers cannot mount directories on a different drive, and mount point cannot be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\ , but not D:\my\path:C:\my\path or D:\:C:\my\path .
When the host parameter is used, specify a sourcePath to declare the path on the host container instance that is presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value does not exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
If you are using the Fargate launch type, the sourcePath parameter is not supported.
This parameter is specified when you are using Docker volumes.
Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.
Note
Docker volumes are not supported by tasks run on Fargate.
The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.
If this value is true , the Docker volume is created if it does not already exist.
Note
This field is only used if the scope is shared .
The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. For more information, see Docker plugin discovery . This parameter maps to Driver in the Create a volume section of the Docker Remote API and the xxdriver option to docker volume create .
A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the Create a volume section of the Docker Remote API and the xxopt option to docker volume create .
Custom metadata to add to your Docker volume. This parameter maps to Labels in the Create a volume section of the Docker Remote API and the xxlabel option to docker volume create .
This parameter is specified when you are using an Amazon Elastic File System file system for task storage.
The Amazon EFS file system ID to use.
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.
Whether or not to enable encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be enabled if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting Data in Transit in the Amazon Elastic File System User Guide .
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server.

You can apply custom attributes, specified as key-value pairs using the Amazon ECS console or the PutAttributes API. These attributes are used when considering task placement for tasks hosted on Amazon EC2 instances. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .
Note
This parameter is not supported for tasks run on Fargate.
An attribute is a name-value pair associated with an Amazon ECS object. Attributes enable you to extend the Amazon ECS data model by adding custom metadata to your resources. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .

The task launch types the task definition validated against during task definition registration. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
The task launch types the task definition was validated against. To determine which task launch types the task definition is validated for, see the TaskDefinition$compatibilities parameter.
The number of cpu units used by the task. If you are using the EC2 launch type, this field is optional and any value can be used. If you are using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of valid values for the memory parameter:
The amount (in MiB) of memory used by the task.
If your tasks will be run on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified then the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see ContainerDefinition .
If your tasks will be run on Fargate, this field is required and you must use one of the following values, which determines your range of valid values for the cpu parameter:

The Elastic Inference accelerator type to use.
The process namespace to use for the containers in the task. The valid values are host or task . If host is specified, then all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same process namespace. If no value is specified, the default is a private namespace. For more information, see PID settings in the Docker run reference .
If the host PID mode is used, be aware that there is a heightened risk of undesired process namespace expose. For more information, see Docker security .
Note
This parameter is not supported for Windows containers or tasks run on Fargate.
The IPC resource namespace to use for the containers in the task. The valid values are host , task , or none . If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference .
If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security .
If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide .
Note
This parameter is not supported for Windows containers or tasks run on Fargate.
The configuration details for the App Mesh proxy.
Your Amazon ECS container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to enable a proxy configuration.

The value to set for the cluster setting. The supported values are enabled and disabled . If enabled is specified, CloudWatch Container Insights will be enabled for the cluster, otherwise it will be disabled unless the containerInsights account setting is enabled. If a cluster value is specified, it will override the containerInsights value set with PutAccountSetting or PutAccountSettingDefault .
capacityProviders (list) --

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

When the stringSetValue type is set, the value of the resource must be a string type.
registeredResources (list) --
For CPU and memory resource types, this parameter describes the amount of each resource that was available on the container instance when the container agent registered it with Amazon ECS. This value represents the total amount of CPU and memory that can be allocated on this container instance to tasks. For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent when it registered the container instance with Amazon ECS.

status (string) --
The status of the container instance. The valid values are REGISTERING , REGISTRATION_FAILED , ACTIVE , INACTIVE , DEREGISTERING , or DRAINING .
If your account has opted in to the awsvpcTrunking account setting, then any newly registered container instance will transition to a REGISTERING status while the trunk elastic network interface is provisioned for the instance. If the registration fails, the instance will transition to a REGISTRATION_FAILED status. You can describe the container instance and see the reason for failure in the statusReason parameter. Once the container instance is terminated, the instance transitions to a DEREGISTERING status while the trunk elastic network interface is deprovisioned. The instance then transitions to an INACTIVE status.
The ACTIVE status indicates that the container instance can accept tasks. The DRAINING indicates that new tasks are not placed on the container instance and any service tasks running on the container instance are removed if possible. For more information, see Container Instance Draining in the Amazon Elastic Container Service Developer Guide .
statusReason (string) --
The reason that the container instance reached its current status.

Response Structure
(dict) --
services (list) --
The list of services described.
(dict) --
Details on a service within a cluster
serviceArn (string) --
The ARN that identifies the service. The ARN contains the arn:aws:ecs namespace, followed by the Region of the service, the account ID of the service owner, the service namespace, and then the service name. For example, arn:aws:ecs:region:012345678910:service/my-service .
serviceName (string) --
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that hosts the service.
loadBalancers (list) --
A list of Elastic Load Balancing load balancer objects, containing the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer.
(dict) --
The load balancer configuration to use with a service or task set.
For specific notes and restrictions regarding the use of load balancers with services and task sets, see the CreateService and CreateTaskSet actions.
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they are launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details of the service discovery registries to assign to this service. For more information, see Service Discovery .
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .
port (integer) --
The port value used if your service discovery service specified an SRV record. This field may be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
status (string) --
The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .
desiredCount (integer) --
The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .
runningCount (integer) --
The number of tasks in the cluster that are in the RUNNING state.
pendingCount (integer) --
The number of tasks in the cluster that are in the PENDING state.
launchType (string) --
The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.
capacityProviderStrategy (list) --
The capacity provider strategy the service is using. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --
The platform version on which to run your service. A platform version is only specified for tasks hosted on Fargate. If one is not specified, the LATEST platform version is used by default. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
taskDefinition (string) --
The task definition to use for tasks in the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .
deploymentConfiguration (dict) --
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker (dict) --
Note
The deployment circuit breaker can only be used for services using the rolling update (ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If deployment circuit breaker is enabled, a service deployment will transition to a failed state and stop launching new tasks. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
enable (boolean) --
Whether to enable the deployment circuit breaker logic for the service.
rollback (boolean) --
Whether to enable Amazon ECS to roll back the service if a service deployment fails. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent (integer) --
If a service is using the rolling update (ECS ) deployment type, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimumHealthyPercent (integer) --
If a service is using the rolling update (ECS ) deployment type, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in the RUNNING state during a deployment, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.
taskSets (list) --
Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.

id (string) --
The ID of the task set.
taskSetArn (string) --
The Amazon Resource Name (ARN) of the task set.
serviceArn (string) --
The Amazon Resource Name (ARN) of the service the task set exists in.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that the service that hosts the task set exists in.
startedBy (string) --
The tag specified when a task set is started. If the task set is created by an CodeDeploy deployment, the startedBy parameter is CODE_DEPLOY . For a task set created for an external deployment, the startedBy field isn't used.
externalId (string) --
The external ID associated with the task set.
If a task set is created by an CodeDeploy deployment, the externalId parameter contains the CodeDeploy deployment ID.
If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.
status (string) --
The status of the task set. The following describes each state:
PRIMARY
The task set is serving production traffic.
ACTIVE
The task set is not serving production traffic.
DRAINING
The tasks in the task set are being stopped and their corresponding targets are being deregistered from their target group.
taskDefinition (string) --
The task definition the task set is using.
computedDesiredCount (integer) --
The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.
pendingCount (integer) --
The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it is restarted after being in the STOPPED state.
runningCount (integer) --
The number of tasks in the task set that are in the RUNNING status during a deployment. A task in the RUNNING state is running and ready for use.
createdAt (datetime) --
The Unix timestamp for when the task set was created.
updatedAt (datetime) --

launchType (string) --
The launch type the tasks in the task set are using. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
capacityProviderStrategy (list) --
The capacity provider strategy associated with the task set.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --

Note
All specified subnets must be from the same VPC.
securityGroups (list) --
The IDs of the security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
loadBalancers (list) --
Details on a load balancer that is used with a task set.

The load balancer configuration to use with a service or task set.
For specific notes and restrictions regarding the use of load balancers with services and task sets, see the CreateService and CreateTaskSet actions.
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they are launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details of the service discovery registries to assign to this task set. For more information, see Service discovery .
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .
port (integer) --
The port value used if your service discovery service specified an SRV record. This field may be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
scale (dict) --
A floating-point percentage of the desired number of tasks to place and keep running in the task set.
value (float) --
The value, specified as a percent total of a service's desiredCount , to scale the task set. Accepted values are numbers between 0 and 100.
unit (string) --
The unit of measure for the scale value.
stabilityStatus (string) --

If any of those conditions are not met, the stability status returns STABILIZING .
stabilityStatusAt (datetime) --
The Unix timestamp for when the task set stability status was retrieved.
tags (list) --
The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
(dict) --
The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
deployments (list) --
The current state of deployments for the service.
(dict) --
The details of an Amazon ECS service deployment. This is used only when a service uses the ECS deployment controller type.
id (string) --
The ID of the deployment.
status (string) --
The status of the deployment. The following describes each state:
PRIMARY
The most recent deployment of a service.
ACTIVE
A service deployment that still has running tasks, but are in the process of being replaced with a new PRIMARY deployment.
INACTIVE
A deployment that has been completely replaced.
taskDefinition (string) --
The most recent task definition that was specified for the tasks in the service to use.
desiredCount (integer) --
The most recent desired count of tasks that was specified for the service to deploy or maintain.
pendingCount (integer) --
The number of tasks in the deployment that are in the PENDING status.
runningCount (integer) --
The number of tasks in the deployment that are in the RUNNING status.
failedTasks (integer) --
The number of consecutively failed tasks in the deployment. A task is considered a failure if the service scheduler can't launch the task, the task doesn't transition to a RUNNING state, or if it fails any of its defined health checks and is stopped.
Note
Once a service deployment has one or more successfully running tasks, the failed task count resets to zero and stops being evaluated.
createdAt (datetime) --
The Unix timestamp for when the service deployment was created.
updatedAt (datetime) --
The Unix timestamp for when the service deployment was last updated.
capacityProviderStrategy (list) --
The capacity provider strategy that the deployment is using.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
launchType (string) --
The launch type the tasks in the service are using. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide .
platformVersion (string) --
The platform version on which your tasks in the service are running. A platform version is only specified for tasks using the Fargate launch type. If one is not specified, the LATEST platform version is used by default. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
networkConfiguration (dict) --
The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.
awsvpcConfiguration (dict) --
The VPC subnets and security groups associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
subnets (list) --
The IDs of the subnets associated with the task or service. There is a limit of 16 subnets that can be specified per AwsVpcConfiguration .
Note
All specified subnets must be from the same VPC.
securityGroups (list) --

Note
All specified security groups must be from the same VPC.
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
rolloutState (string) --
Note
The rolloutState of a service is only returned for services that use the rolling update (ECS ) deployment type that are not behind a Classic Load Balancer.
The rollout state of the deployment. When a service deployment is started, it begins in an IN_PROGRESS state. When the service reaches a steady state, the deployment will transition to a COMPLETED state. If the service fails to reach a steady state and circuit breaker is enabled, the deployment will transition to a FAILED state. A deployment in FAILED state will launch no new tasks. For more information, see DeploymentCircuitBreaker .
rolloutStateReason (string) --
A description of the rollout state of a deployment.
roleArn (string) --
The ARN of the IAM role associated with the service that allows the Amazon ECS container agent to register container instances with an Elastic Load Balancing load balancer.

(dict) --
Details on an event associated with a service.
id (string) --
The ID string of the event.
createdAt (datetime) --
The Unix timestamp for when the event was triggered.
message (string) --
The event message.
createdAt (datetime) --
The Unix timestamp for when the service was created.
placementConstraints (list) --
The placement constraints for the tasks in the service.
(dict) --
An object representing a constraint on task placement. For more information, see Task Placement Constraints in the Amazon Elastic Container Service Developer Guide .
Note
If you are using the Fargate launch type, task placement constraints are not supported.
type (string) --
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
expression (string) --
A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is distinctInstance . For more information, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide .
placementStrategy (list) --
The placement strategy that determines how tasks for the service are placed.
(dict) --
The task placement strategy for a task or service. For more information, see Task Placement Strategies in the Amazon Elastic Container Service Developer Guide .
type (string) --
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that is specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory (but still enough to run the task).
field (string) --
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
networkConfiguration (dict) --

Note
All specified subnets must be from the same VPC.
securityGroups (list) --
The IDs of the security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
healthCheckGracePeriodSeconds (integer) --
The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started.
schedulingStrategy (string) --
The scheduling strategy to use for the service. For more information, see Services .
There are two service scheduler strategies available:
Note
Fargate tasks do not support the DAEMON scheduling strategy.
deploymentController (dict) --
The deployment controller type the service is using. When using the DescribeServices API, this field is omitted if the service is using the ECS deployment controller type.
type (string) --
The deployment controller type to use.
There are three deployment controller types available:
ECS
The rolling update (ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration .
CODE_DEPLOY
The blue/green (CODE_DEPLOY ) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.
EXTERNAL
The external (EXTERNAL ) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.

Response Structure
(dict) --
taskDefinition (dict) --
The full task definition description.
taskDefinitionArn (string) --
The full Amazon Resource Name (ARN) of the task definition.
containerDefinitions (list) --
A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide .
(dict) --
Container definitions are used in task definitions to describe the different containers that are launched as part of a task.
name (string) --
The name of a container. If you are linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run .
image (string) --
The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with either `` repository-url /image :tag `` or `` repository-url /image @*digest* `` . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run .
repositoryCredentials (dict) --
The private repository authentication credentials to use.
credentialsParameter (string) --
The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note
When you are using the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you are launching then you can use either the full ARN or the name of the secret. When you are using the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu (integer) --
The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run .
This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.
Note
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that is the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that is described in the task definition. A null or zero CPU value is passed to Docker as 0 , which Windows interprets as 1% of one CPU.
memory (integer) --
The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run .
If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance on which the container is placed. Otherwise, the value of memory is used.
The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.
memoryReservation (integer) --
The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run .
If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance on which the container is placed. Otherwise, the value of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.
The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.
links (list) --
The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge . The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run .
Note
This parameter is not supported for Windows containers.
Warning
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
portMappings (list) --
The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the awsvpc network mode, you should only specify the containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Port mappings on Windows use the NetNAT gateway address rather than localhost . There is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself.
This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run . If the network mode of a task definition is set to none , then you can't specify port mappings. If the network mode of a task definition is set to host , then host ports must either be undefined or they must match the container port in the port mapping.
Note
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
(dict) --
Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.
If you are using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Note
You cannot expose the same container port for multiple protocols. An error will be returned if this is attempted
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.
containerPort (integer) --
The port number on the container that is bound to the user-specified or automatically assigned host port.
If you are using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort .
If you are using containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort . Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.
hostPort (integer) --
The port number on the container instance to reserve for your container.
If you are using containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort .
If you are using containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0 ) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.
The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range . If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.
Note
The default ephemeral port range from 49153 through 65535 is always used for Docker versions before 1.6.0.
The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running (after a task stops, the host port is released). The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time, including the default reserved ports. Automatically assigned ports don't count toward the 100 reserved ports limit.
protocol (string) --
The protocol used for the port mapping. Valid values are tcp and udp . The default is tcp .
essential (boolean) --
If the essential parameter of a container is marked as true , and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false , then its failure does not affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that is composed of multiple containers, you should group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide .

Lines beginning with # are treated as comments and are ignored. For more information on the environment variable file syntax, see Declare default environment variables in file .
If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they are processed from the top down. It is recommended to use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide .

maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.
If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
If you are using tasks that use the Fargate launch type, the maxSwap parameter is not supported.
swappiness (integer) --
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run .

The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
Note
If the SSM Parameter Store parameter exists in the same Region as the task you are launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
dependsOn (list) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to enable container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
For tasks using the Fargate launch type, the task or service requires platform version 1.3.0 or later.
(dict) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
Your Amazon ECS container instances require at least version 1.26.0 of the container agent to enable container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init .

The name of a container.
condition (string) --
The dependency condition of the container. The following are the available conditions and their behavior:
startTimeout (integer) --
Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE , SUCCESS , or HEALTHY status. If a startTimeout value is specified for containerB and it does not reach the desired status within that time then containerA will give up and not start. This results in the task transitioning to a STOPPED state.
Note
When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it is enforced indendently from this start timeout value.
For tasks using the Fargate launch type, this parameter requires that the task or service uses platform version 1.3.0 or later.
For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to enable a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
stopTimeout (integer) --
Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires platform version 1.3.0 or later. The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks using the EC2 launch type, if the stopTimeout parameter is not specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used by default. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to enable a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .

This parameter maps to SecurityOpt in the Create a container section of the Docker Remote API and the --security-opt option to docker run .
Note
The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
For more information about valid values, see Docker Run Security Configuration .
Valid values: "no-new-privileges" | "apparmor:PROFILE" | "label:value" | "credentialspec:CredentialSpecFilePath"

The hard limit for the ulimit type.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run . By default, containers use the same logging driver that the Docker daemon uses. However the container may use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
logDriver (string) --
The log driver to use for the container.

If you have a custom driver that is not listed, you can fork the Amazon ECS container agent project that is available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we do not currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
secretOptions (list) --
The secrets to pass to the log configuration. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the secret.
valueFrom (string) --
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
Note
If the SSM Parameter Store parameter exists in the same Region as the task you are launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
healthCheck (dict) --
The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run .
command (list) --
A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to execute the command arguments directly, or CMD-SHELL to run the command with the container's default shell. For example:
[ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]
An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in the Create a container section of the Docker Remote API .
interval (integer) --
The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.
timeout (integer) --
The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.
retries (integer) --
The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.
startPeriod (integer) --
The optional grace period within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You may specify between 0 and 300 seconds. The startPeriod is disabled by default.
Note
If a health check succeeds within the startPeriod , then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
systemControls (list) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run .
Note
It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. For tasks that use the awsvpc network mode, the container that is started last determines which systemControls parameters take effect. For tasks that use the host network mode, it changes the container instance's namespaced kernel parameters as well as the containers.
(dict) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run .
It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network mode for the following reasons:
namespace (string) --
The namespaced kernel parameter for which to set a value .
value (string) --
The value for the namespaced kernel parameter specified in namespace .
resourceRequirements (list) --
The type and amount of a resource to assign to a container. The only supported resource is a GPU.
(dict) --
The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see Working with GPUs on Amazon ECS or Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide
value (string) --
The value for the specified resource type.
If the GPU type is used, the value is the number of physical GPUs the Amazon ECS container agent will reserve for the container. The number of GPUs reserved for all containers in a task should not exceed the number of available GPUs on the container instance the task is launched on.
If the InferenceAccelerator type is used, the value should match the deviceName for an InferenceAccelerator specified in a task definition.
type (string) --
The type of resource to assign to a container. The supported values are GPU or InferenceAccelerator .
firelensConfiguration (dict) --
The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide .
type (string) --
The log router to use. The valid values are fluentd or fluentbit .
options (dict) --
The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"} . For more information, see Creating a Task Definition that Uses a FireLens Configuration in the Amazon Elastic Container Service Developer Guide .
Note
Tasks hosted on Fargate only support the file configuration file type.
family (string) --
The name of a family that this task definition is registered to. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
taskRoleArn (string) --
The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide .
IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code in order to take advantage of the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide .
executionRoleArn (string) --
The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide .
networkMode (string) --
The Docker networking mode to use for the containers in the task. The valid values are none , bridge , awsvpc , and host . If no network mode is specified, the default is bridge .
For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none , you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.
With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.
Warning
When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.
If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .
If the network mode is host , you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.
For more information, see Network settings in the Docker run reference .
revision (integer) --
The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is 1 . Each time that you register a new revision of a task definition in the same family, the revision value always increases by one, even if you have deregistered previous revisions in this family.
volumes (list) --
The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide .
Note
The host and sourcePath parameters are not supported for tasks run on Fargate.
(dict) --
A data volume used in a task definition. For tasks that use the Amazon Elastic File System (Amazon EFS), specify an efsVolumeConfiguration . For Windows tasks that use Amazon FSx for Windows File Server file system, specify a fsxWindowsFileServerVolumeConfiguration . For tasks that use a Docker volume, specify a DockerVolumeConfiguration . For tasks that use a bind mount host volume, specify a host and optional sourcePath . For more information, see Using Data Volumes in Tasks .
name (string) --
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints .
host (dict) --
This parameter is specified when you are using bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data is not guaranteed to persist after the containers associated with it stop running.
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers cannot mount directories on a different drive, and mount point cannot be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\ , but not D:\my\path:C:\my\path or D:\:C:\my\path .
sourcePath (string) --
When the host parameter is used, specify a sourcePath to declare the path on the host container instance that is presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value does not exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
If you are using the Fargate launch type, the sourcePath parameter is not supported.
dockerVolumeConfiguration (dict) --
This parameter is specified when you are using Docker volumes.
Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.
Note
Docker volumes are not supported by tasks run on Fargate.
scope (string) --
The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.
autoprovision (boolean) --
If this value is true , the Docker volume is created if it does not already exist.
Note
This field is only used if the scope is shared .
driver (string) --
The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. For more information, see Docker plugin discovery . This parameter maps to Driver in the Create a volume section of the Docker Remote API and the xxdriver option to docker volume create .
driverOpts (dict) --
A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the Create a volume section of the Docker Remote API and the xxopt option to docker volume create .
labels (dict) --
Custom metadata to add to your Docker volume. This parameter maps to Labels in the Create a volume section of the Docker Remote API and the xxlabel option to docker volume create .

This parameter is specified when you are using an Amazon Elastic File System file system for task storage.
fileSystemId (string) --
The Amazon EFS file system ID to use.
rootDirectory (string) --
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.
transitEncryption (string) --
Whether or not to enable encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be enabled if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting Data in Transit in the Amazon Elastic File System User Guide .
transitEncryptionPort (integer) --
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS Mount Helper in the Amazon Elastic File System User Guide .
authorizationConfig (dict) --
The authorization configuration details for the Amazon EFS file system.
accessPointId (string) --
The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be enabled in the EFSVolumeConfiguration . For more information, see Working with Amazon EFS Access Points in the Amazon Elastic File System User Guide .
iam (string) --
Whether or not to use the Amazon ECS task IAM role defined in a task definition when mounting the Amazon EFS file system. If enabled, transit encryption must be enabled in the EFSVolumeConfiguration . If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS Access Points in the Amazon Elastic Container Service Developer Guide .

A fully qualified domain name hosted by an Directory Service Managed Microsoft AD (Active Directory) or self-hosted AD on Amazon EC2.
status (string) --
The status of the task definition.
requiresAttributes (list) --
The container instance attributes required by your task. When an Amazon EC2 instance is registered to your cluster, the Amazon ECS container agent assigns some standard attributes to the instance. You can apply custom attributes, specified as key-value pairs using the Amazon ECS console or the PutAttributes API. These attributes are used when considering task placement for tasks hosted on Amazon EC2 instances. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .
Note
This parameter is not supported for tasks run on Fargate.

A cluster query language expression to apply to the constraint. For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .
compatibilities (list) --
The task launch types the task definition validated against during task definition registration. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
requiresCompatibilities (list) --
The task launch types the task definition was validated against. To determine which task launch types the task definition is validated for, see the TaskDefinition$compatibilities parameter.
cpu (string) --
The number of cpu units used by the task. If you are using the EC2 launch type, this field is optional and any value can be used. If you are using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of valid values for the memory parameter:
memory (string) --
The amount (in MiB) of memory used by the task.
If your tasks will be run on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified then the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see ContainerDefinition .
If your tasks will be run on Fargate, this field is required and you must use one of the following values, which determines your range of valid values for the cpu parameter:
inferenceAccelerators (list) --
The Elastic Inference accelerator associated with the task.
(dict) --
Details on a Elastic Inference accelerator. For more information, see Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide .
deviceName (string) --
The Elastic Inference accelerator device name. The deviceName must also be referenced in a container definition as a ResourceRequirement .
deviceType (string) --
The Elastic Inference accelerator type to use.
pidMode (string) --
The process namespace to use for the containers in the task. The valid values are host or task . If host is specified, then all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same process namespace. If no value is specified, the default is a private namespace. For more information, see PID settings in the Docker run reference .
If the host PID mode is used, be aware that there is a heightened risk of undesired process namespace expose. For more information, see Docker security .
Note
This parameter is not supported for Windows containers or tasks run on Fargate.
ipcMode (string) --
The IPC resource namespace to use for the containers in the task. The valid values are host , task , or none . If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference .
If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security .
If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide .

Response Structure
(dict) --
taskSets (list) --
The list of task sets described.
(dict) --
Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.
id (string) --
The ID of the task set.
taskSetArn (string) --
The Amazon Resource Name (ARN) of the task set.
serviceArn (string) --
The Amazon Resource Name (ARN) of the service the task set exists in.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that the service that hosts the task set exists in.
startedBy (string) --
The tag specified when a task set is started. If the task set is created by an CodeDeploy deployment, the startedBy parameter is CODE_DEPLOY . For a task set created for an external deployment, the startedBy field isn't used.
externalId (string) --
The external ID associated with the task set.
If a task set is created by an CodeDeploy deployment, the externalId parameter contains the CodeDeploy deployment ID.
If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.
status (string) --
The status of the task set. The following describes each state:
PRIMARY
The task set is serving production traffic.
ACTIVE
The task set is not serving production traffic.
DRAINING
The tasks in the task set are being stopped and their corresponding targets are being deregistered from their target group.
taskDefinition (string) --
The task definition the task set is using.
computedDesiredCount (integer) --
The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.
pendingCount (integer) --
The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it is restarted after being in the STOPPED state.
runningCount (integer) --
The number of tasks in the task set that are in the RUNNING status during a deployment. A task in the RUNNING state is running and ready for use.
createdAt (datetime) --
The Unix timestamp for when the task set was created.
updatedAt (datetime) --
The Unix timestamp for when the task set was last updated.
launchType (string) --
The launch type the tasks in the task set are using. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
capacityProviderStrategy (list) --
The capacity provider strategy associated with the task set.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --
The Fargate platform version on which the tasks in the task set are running. A platform version is only specified for tasks run on Fargate. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide .
networkConfiguration (dict) --

The VPC subnets and security groups associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
subnets (list) --

Note
All specified subnets must be from the same VPC.
securityGroups (list) --
The IDs of the security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .

Details on a load balancer that is used with a task set.
(dict) --
The load balancer configuration to use with a service or task set.
For specific notes and restrictions regarding the use of load balancers with services and task sets, see the CreateService and CreateTaskSet actions.
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --

The task desired status to use when filtering the ListTasks results. Specifying a desiredStatus of STOPPED limits the results to tasks that Amazon ECS has set the desired status to STOPPED . This can be useful for debugging tasks that are not starting properly or have died or finished. The default status filter is RUNNING , which shows tasks that Amazon ECS has set the desired status to RUNNING .
Note
Although you can filter results based on a desired status of PENDING , this does not return any results. Amazon ECS never sets the desired status of a task to that value (only a task's lastStatus may have a value of PENDING ).

[REQUIRED]
The name of one or more capacity providers to associate with the cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.
[REQUIRED]
The capacity provider strategy to use by default for the cluster.
When creating a service or running a task on a cluster, if no capacity provider or launch type is specified then the default capacity provider strategy for the cluster is used.
A capacity provider strategy consists of one or more capacity providers along with the base and weight to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with an ACTIVE or UPDATING status can be used.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
The short name of the capacity provider.
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

Registers a new task definition from the supplied family and containerDefinitions . Optionally, you can add data volumes to your containers with the volumes parameter. For more information about task definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide .
You can specify an IAM role for your task with the taskRoleArn parameter. When you specify an IAM role for a task, its containers can then use the latest versions of the CLI or SDKs to make API requests to the Amazon Web Services services that are specified in the IAM policy associated with the role. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide .
You can specify a Docker networking mode for the containers in your task definition with the networkMode parameter. The available network modes correspond to those described in Network settings in the Docker run reference. If you specify the awsvpc network mode, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration when you create a service or run a task with the task definition.

[REQUIRED]
You must specify a family for a task definition, which allows you to track multiple versions of the same task definition. The family is used as a name for your task definition. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
The Docker networking mode to use for the containers in the task. The valid values are none , bridge , awsvpc , and host . If no network mode is specified, the default is bridge .
For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none , you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.
With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.
Warning
When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.
If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .
If the network mode is host , you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.
For more information, see Network settings in the Docker run reference .
[REQUIRED]
A list of container definitions in JSON format that describe the different containers that make up your task.
Container definitions are used in task definitions to describe the different containers that are launched as part of a task.
The name of a container. If you are linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run .
The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with either `` repository-url /image :tag `` or `` repository-url /image @*digest* `` . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run .
The private repository authentication credentials to use.
The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note
When you are using the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you are launching then you can use either the full ARN or the name of the secret. When you are using the Amazon Web Services Management Console, you must specify the full ARN of the secret.
The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run .
This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.
Note
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that is the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that is described in the task definition. A null or zero CPU value is passed to Docker as 0 , which Windows interprets as 1% of one CPU.
The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run .
If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance on which the container is placed. Otherwise, the value of memory is used.
The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.
The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run .
If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance on which the container is placed. Otherwise, the value of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.
The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.
The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge . The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run .
Note
This parameter is not supported for Windows containers.
Warning
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the awsvpc network mode, you should only specify the containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Port mappings on Windows use the NetNAT gateway address rather than localhost . There is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself.
This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run . If the network mode of a task definition is set to none , then you can't specify port mappings. If the network mode of a task definition is set to host , then host ports must either be undefined or they must match the container port in the port mapping.
Note
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.
If you are using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Note
You cannot expose the same container port for multiple protocols. An error will be returned if this is attempted
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.
The port number on the container that is bound to the user-specified or automatically assigned host port.
If you are using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort .
If you are using containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort . Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.
The port number on the container instance to reserve for your container.
If you are using containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort .
If you are using containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0 ) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.
The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range . If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.
Note
The default ephemeral port range from 49153 through 65535 is always used for Docker versions before 1.6.0.
The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running (after a task stops, the host port is released). The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time, including the default reserved ports. Automatically assigned ports don't count toward the 100 reserved ports limit.
The protocol used for the port mapping. Valid values are tcp and udp . The default is tcp .
If the essential parameter of a container is marked as true , and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false , then its failure does not affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that is composed of multiple containers, you should group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide .
Warning
Early versions of the Amazon ECS container agent do not properly handle entryPoint parameters. If you have problems using entryPoint , update your container agent or enter your commands and arguments as command array items instead.
The entry point that is passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run . For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint .
The command that is passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run . For more information, see https://docs.docker.com/engine/reference/builder/#cmd . If there are multiple arguments, each argument should be a separated string in the array.
The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run .
Warning
We do not recommend using plaintext environment variables for sensitive information, such as credential data.
A key-value pair object.
The name of the key-value pair. For environment variables, this is the name of the environment variable.
The value of the key-value pair. For environment variables, this is the value of the environment variable.
A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run .
You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file should contain an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored. For more information on the environment variable file syntax, see Declare default environment variables in file .
If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they are processed from the top down. It is recommended to use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide .

This field is only valid for containers in Fargate tasks that use platform version 1.4.0 or later.
The Amazon Resource Name (ARN) of the Amazon S3 object containing the environment variable file.
The file type to use. The only supported value is s3 .
The mount points for data volumes in your container.
This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run .
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers cannot mount directories on a different drive, and mount point cannot be across drives.
Details on a volume mount point that is used in a container definition.
The name of the volume to mount. Must be a volume name referenced in the name parameter of task definition volume .
The path on the container to mount the host volume at.
If this value is true , the container has read-only access to the volume. If this value is false , then the container can write to the volume. The default value is false .
Data volumes to mount from another container. This parameter maps to VolumesFrom in the Create a container section of the Docker Remote API and the --volumes-from option to docker run .
Details on a data volume from another container in the same task definition.
The name of another container within the same task definition from which to mount volumes.
If this value is true , the container has read-only access to the volume. If this value is false , then the container can write to the volume. The default value is false .
Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information see KernelCapabilities .
Note
This parameter is not supported for Windows containers.
The Linux capabilities for the container that are added to or dropped from the default configuration provided by Docker.
Note
For tasks that use the Fargate launch type, capabilities is supported for all platform versions but the add parameter is only supported if using platform version 1.4.0 or later.
The Linux capabilities for the container that have been added to the default configuration provided by Docker. This parameter maps to CapAdd in the Create a container section of the Docker Remote API and the --cap-add option to docker run .
Note
Tasks launched on Fargate only support adding the SYS_PTRACE kernel capability.

The Linux capabilities for the container that have been removed from the default configuration provided by Docker. This parameter maps to CapDrop in the Create a container section of the Docker Remote API and the --cap-drop option to docker run .
Valid values: "ALL" | "AUDIT_CONTROL" | "AUDIT_WRITE" | "BLOCK_SUSPEND" | "CHOWN" | "DAC_OVERRIDE" | "DAC_READ_SEARCH" | "FOWNER" | "FSETID" | "IPC_LOCK" | "IPC_OWNER" | "KILL" | "LEASE" | "LINUX_IMMUTABLE" | "MAC_ADMIN" | "MAC_OVERRIDE" | "MKNOD" | "NET_ADMIN" | "NET_BIND_SERVICE" | "NET_BROADCAST" | "NET_RAW" | "SETFCAP" | "SETGID" | "SETPCAP" | "SETUID" | "SYS_ADMIN" | "SYS_BOOT" | "SYS_CHROOT" | "SYS_MODULE" | "SYS_NICE" | "SYS_PACCT" | "SYS_PTRACE" | "SYS_RAWIO" | "SYS_RESOURCE" | "SYS_TIME" | "SYS_TTY_CONFIG" | "SYSLOG" | "WAKE_ALARM"
Any host devices to expose to the container. This parameter maps to Devices in the Create a container section of the Docker Remote API and the --device option to docker run .
Note
If you are using tasks that use the Fargate launch type, the devices parameter is not supported.
An object representing a container instance host device.
The path for the device on the host container instance.
The path inside the container at which to expose the host device.
The explicit permissions to provide to the container for the device. By default, the container has permissions for read , write , and mknod for the device.
Run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run . This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run .
Note
If you are using tasks that use the Fargate launch type, the sharedMemorySize parameter is not supported.
The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run .
Note
If you are using tasks that use the Fargate launch type, the tmpfs parameter is not supported.
The container path, mount options, and size of the tmpfs mount.
The absolute file path where the tmpfs volume is to be mounted.
The maximum size (in MiB) of the tmpfs volume.
The list of tmpfs volume mount options.
Valid values: "defaults" | "ro" | "rw" | "suid" | "nosuid" | "dev" | "nodev" | "exec" | "noexec" | "sync" | "async" | "dirsync" | "remount" | "mand" | "nomand" | "atime" | "noatime" | "diratime" | "nodiratime" | "bind" | "rbind" | "unbindable" | "runbindable" | "private" | "rprivate" | "shared" | "rshared" | "slave" | "rslave" | "relatime" | "norelatime" | "strictatime" | "nostrictatime" | "mode" | "uid" | "gid" | "nr_inodes" | "nr_blocks" | "mpol"
The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.
If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
If you are using tasks that use the Fargate launch type, the maxSwap parameter is not supported.
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run .
Note
If you are using tasks that use the Fargate launch type, the swappiness parameter is not supported.
The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
The name of the secret.
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
Note
If the SSM Parameter Store parameter exists in the same Region as the task you are launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to enable container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
For tasks using the Fargate launch type, the task or service requires platform version 1.3.0 or later.
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
Your Amazon ECS container instances require at least version 1.26.0 of the container agent to enable container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
Note
For tasks using the Fargate launch type, this parameter requires that the task or service uses platform version 1.3.0 or later.
The name of a container.
The dependency condition of the container. The following are the available conditions and their behavior:
Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE , SUCCESS , or HEALTHY status. If a startTimeout value is specified for containerB and it does not reach the desired status within that time then containerA will give up and not start. This results in the task transitioning to a STOPPED state.
Note
When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it is enforced indendently from this start timeout value.
For tasks using the Fargate launch type, this parameter requires that the task or service uses platform version 1.3.0 or later.
For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to enable a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires platform version 1.3.0 or later. The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks using the EC2 launch type, if the stopTimeout parameter is not specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used by default. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to enable a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
The hostname to use for your container. This parameter maps to Hostname in the Create a container section of the Docker Remote API and the --hostname option to docker run .
Note
The hostname parameter is not supported if you are using the awsvpc network mode.
The user to use inside the container. This parameter maps to User in the Create a container section of the Docker Remote API and the --user option to docker run .
Warning
When running tasks using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.
You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer.
Note

The soft limit for the ulimit type.
The hard limit for the ulimit type.
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run . By default, containers use the same logging driver that the Docker daemon uses. However the container may use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries ,``syslog`` , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that is not listed, you can fork the Amazon ECS container agent project that is available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we do not currently provide support for running modified copies of this software.
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
The secrets to pass to the log configuration. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
The name of the secret.
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
Note
If the SSM Parameter Store parameter exists in the same Region as the task you are launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run .
A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to execute the command arguments directly, or CMD-SHELL to run the command with the container's default shell. For example:
[ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]
An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in the Create a container section of the Docker Remote API .
The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.
The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.
The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.
The optional grace period within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You may specify between 0 and 300 seconds. The startPeriod is disabled by default.
Note
If a health check succeeds within the startPeriod , then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run .
Note
It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. For tasks that use the awsvpc network mode, the container that is started last determines which systemControls parameters take effect. For tasks that use the host network mode, it changes the container instance's namespaced kernel parameters as well as the containers.
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run .
It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network mode for the following reasons:
The namespaced kernel parameter for which to set a value .
The value for the namespaced kernel parameter specified in namespace .
The type and amount of a resource to assign to a container. The only supported resource is a GPU.
The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see Working with GPUs on Amazon ECS or Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide
The value for the specified resource type.
If the GPU type is used, the value is the number of physical GPUs the Amazon ECS container agent will reserve for the container. The number of GPUs reserved for all containers in a task should not exceed the number of available GPUs on the container instance the task is launched on.
If the InferenceAccelerator type is used, the value should match the deviceName for an InferenceAccelerator specified in a task definition.
The type of resource to assign to a container. The supported values are GPU or InferenceAccelerator .
The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide .
The log router to use. The valid values are fluentd or fluentbit .
The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"} . For more information, see Creating a Task Definition that Uses a FireLens Configuration in the Amazon Elastic Container Service Developer Guide .
Note
Tasks hosted on Fargate only support the file configuration file type.
A list of volume definitions in JSON format that containers in your task may use.
A data volume used in a task definition. For tasks that use the Amazon Elastic File System (Amazon EFS), specify an efsVolumeConfiguration . For Windows tasks that use Amazon FSx for Windows File Server file system, specify a fsxWindowsFileServerVolumeConfiguration . For tasks that use a Docker volume, specify a DockerVolumeConfiguration . For tasks that use a bind mount host volume, specify a host and optional sourcePath . For more information, see Using Data Volumes in Tasks .
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints .
This parameter is specified when you are using bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data is not guaranteed to persist after the containers associated with it stop running.
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers cannot mount directories on a different drive, and mount point cannot be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\ , but not D:\my\path:C:\my\path or D:\:C:\my\path .
When the host parameter is used, specify a sourcePath to declare the path on the host container instance that is presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value does not exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
If you are using the Fargate launch type, the sourcePath parameter is not supported.
This parameter is specified when you are using Docker volumes.
Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.
Note
Docker volumes are not supported by tasks run on Fargate.
The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.
If this value is true , the Docker volume is created if it does not already exist.
Note
This field is only used if the scope is shared .
The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. For more information, see Docker plugin discovery . This parameter maps to Driver in the Create a volume section of the Docker Remote API and the xxdriver option to docker volume create .
A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the Create a volume section of the Docker Remote API and the xxopt option to docker volume create .
Custom metadata to add to your Docker volume. This parameter maps to Labels in the Create a volume section of the Docker Remote API and the xxlabel option to docker volume create .
This parameter is specified when you are using an Amazon Elastic File System file system for task storage.
The Amazon EFS file system ID to use.
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.
Whether or not to enable encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be enabled if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting Data in Transit in the Amazon Elastic File System User Guide .
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS Mount Helper in the Amazon Elastic File System User Guide .
The authorization configuration details for the Amazon EFS file system.
The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be enabled in the EFSVolumeConfiguration . For more information, see Working with Amazon EFS Access Points in the Amazon Elastic File System User Guide .
Whether or not to use the Amazon ECS task IAM role defined in a task definition when mounting the Amazon EFS file system. If enabled, transit encryption must be enabled in the EFSVolumeConfiguration . If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS Access Points in the Amazon Elastic Container Service Developer Guide .
This parameter is specified when you are using Amazon FSx for Windows File Server file system for task storage.
The Amazon FSx for Windows File Server file system ID to use.
The directory within the Amazon FSx for Windows File Server file system to mount as the root directory inside the host.
The authorization configuration details for the Amazon FSx for Windows File Server file system.

A cluster query language expression to apply to the constraint. For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .
The task launch type that Amazon ECS should validate the task definition against. A client exception is returned if the task definition doesn't validate against the compatibilities specified. If no value is specified, the parameter is omitted from the response.
The number of CPU units used by the task. It can be expressed as an integer using CPU units, for example 1024 , or as a string using vCPUs, for example 1 vCPU or 1 vcpu , in a task definition. String values are converted to an integer indicating the CPU units when the task definition is registered.
Note
Task-level CPU and memory parameters are ignored for Windows containers. We recommend specifying container-level resources for Windows containers.
If you are using the EC2 launch type, this field is optional. Supported values are between 128 CPU units (0.125 vCPUs) and 10240 CPU units (10 vCPUs).
If you are using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of supported values for the memory parameter:
The amount of memory (in MiB) used by the task. It can be expressed as an integer using MiB, for example 1024 , or as a string using GB, for example 1GB or 1 GB , in a task definition. String values are converted to an integer indicating the MiB when the task definition is registered.
Note
Task-level CPU and memory parameters are ignored for Windows containers. We recommend specifying container-level resources for Windows containers.
If using the EC2 launch type, this field is optional.
If using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of supported values for the cpu parameter:
The metadata that you apply to the task definition to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
The process namespace to use for the containers in the task. The valid values are host or task . If host is specified, then all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same process namespace. If no value is specified, the default is a private namespace. For more information, see PID settings in the Docker run reference .
If the host PID mode is used, be aware that there is a heightened risk of undesired process namespace expose. For more information, see Docker security .
Note
This parameter is not supported for Windows containers or tasks run on Fargate.
The IPC resource namespace to use for the containers in the task. The valid values are host , task , or none . If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference .
If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security .
If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide .
Note
This parameter is not supported for Windows containers or tasks run on Fargate.
The configuration details for the App Mesh proxy.
For tasks hosted on Amazon EC2 instances, the container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to enable a proxy configuration. If your container instances are launched from the Amazon ECS-optimized AMI version 20190301 or later, then they contain the required versions of the container agent and ecs-init .

The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with either `` repository-url /image :tag `` or `` repository-url /image @*digest* `` . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run .
repositoryCredentials (dict) --
The private repository authentication credentials to use.
credentialsParameter (string) --
The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note
When you are using the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you are launching then you can use either the full ARN or the name of the secret. When you are using the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu (integer) --
The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run .
This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.
Note
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that is the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task would be guaranteed a minimum of 512 CPU units when needed, and each container could float to higher CPU usage if the other container was not using it, but if both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter is not required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that is described in the task definition. A null or zero CPU value is passed to Docker as 0 , which Windows interprets as 1% of one CPU.
memory (integer) --
The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run .
If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance on which the container is placed. Otherwise, the value of memory is used.
The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.
memoryReservation (integer) --
The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run .
If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance on which the container is placed. Otherwise, the value of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.
The Docker daemon reserves a minimum of 4 MiB of memory for a container, so you should not specify fewer than 4 MiB of memory for your containers.
links (list) --
The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge . The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run .
Note
This parameter is not supported for Windows containers.
Warning
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
portMappings (list) --
The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the awsvpc network mode, you should only specify the containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Port mappings on Windows use the NetNAT gateway address rather than localhost . There is no loopback for port mappings on Windows, so you cannot access a container's mapped port from the host itself.
This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run . If the network mode of a task definition is set to none , then you can't specify port mappings. If the network mode of a task definition is set to host , then host ports must either be undefined or they must match the container port in the port mapping.
Note
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
(dict) --
Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.
If you are using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Note
You cannot expose the same container port for multiple protocols. An error will be returned if this is attempted
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.
containerPort (integer) --
The port number on the container that is bound to the user-specified or automatically assigned host port.
If you are using containers in a task with the awsvpc or host network mode, exposed ports should be specified using containerPort .
If you are using containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort . Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.
hostPort (integer) --
The port number on the container instance to reserve for your container.
If you are using containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort .
If you are using containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0 ) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.
The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range . If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.
Note
The default ephemeral port range from 49153 through 65535 is always used for Docker versions before 1.6.0.
The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running (after a task stops, the host port is released). The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time, including the default reserved ports. Automatically assigned ports don't count toward the 100 reserved ports limit.
protocol (string) --
The protocol used for the port mapping. Valid values are tcp and udp . The default is tcp .
essential (boolean) --
If the essential parameter of a container is marked as true , and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false , then its failure does not affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that is composed of multiple containers, you should group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide .
entryPoint (list) --
Warning
Early versions of the Amazon ECS container agent do not properly handle entryPoint parameters. If you have problems using entryPoint , update your container agent or enter your commands and arguments as command array items instead.
The entry point that is passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run . For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint .

Lines beginning with # are treated as comments and are ignored. For more information on the environment variable file syntax, see Declare default environment variables in file .
If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they are processed from the top down. It is recommended to use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide .

maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.
If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
If you are using tasks that use the Fargate launch type, the maxSwap parameter is not supported.
swappiness (integer) --
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run .

If the SSM Parameter Store parameter exists in the same Region as the task you are launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
dependsOn (list) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to enable container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
For tasks using the Fargate launch type, the task or service requires platform version 1.3.0 or later.
(dict) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
Your Amazon ECS container instances require at least version 1.26.0 of the container agent to enable container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
Note
For tasks using the Fargate launch type, this parameter requires that the task or service uses platform version 1.3.0 or later.
containerName (string) --
The name of a container.
condition (string) --
The dependency condition of the container. The following are the available conditions and their behavior:
startTimeout (integer) --
Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE , SUCCESS , or HEALTHY status. If a startTimeout value is specified for containerB and it does not reach the desired status within that time then containerA will give up and not start. This results in the task transitioning to a STOPPED state.
Note
When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it is enforced indendently from this start timeout value.
For tasks using the Fargate launch type, this parameter requires that the task or service uses platform version 1.3.0 or later.
For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to enable a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
stopTimeout (integer) --
Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires platform version 1.3.0 or later. The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks using the EC2 launch type, if the stopTimeout parameter is not specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used by default. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to enable a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you are using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
hostname (string) --
The hostname to use for your container. This parameter maps to Hostname in the Create a container section of the Docker Remote API and the --hostname option to docker run .
Note
The hostname parameter is not supported if you are using the awsvpc network mode.

This parameter maps to SecurityOpt in the Create a container section of the Docker Remote API and the --security-opt option to docker run .
Note
The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
For more information about valid values, see Docker Run Security Configuration .

ulimits (list) --
A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it will override the default values set by Docker. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run . Valid naming values are displayed in the Ulimit data type.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and hard limit is 4096 .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
This parameter is not supported for Windows containers.
(dict) --
The ulimit settings to pass to the container.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and hard limit is 4096 .
name (string) --
The type of the ulimit .
softLimit (integer) --
The soft limit for the ulimit type.
hardLimit (integer) --
The hard limit for the ulimit type.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run . By default, containers use the same logging driver that the Docker daemon uses. However the container may use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
logDriver (string) --
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries ,``syslog`` , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that is not listed, you can fork the Amazon ECS container agent project that is available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we do not currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
secretOptions (list) --
The secrets to pass to the log configuration. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the secret.
valueFrom (string) --
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
Note
If the SSM Parameter Store parameter exists in the same Region as the task you are launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
healthCheck (dict) --
The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run .
command (list) --
A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to execute the command arguments directly, or CMD-SHELL to run the command with the container's default shell. For example:
[ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]
An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in the Create a container section of the Docker Remote API .
interval (integer) --
The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.
timeout (integer) --
The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.
retries (integer) --
The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.
startPeriod (integer) --
The optional grace period within which to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You may specify between 0 and 300 seconds. The startPeriod is disabled by default.
Note
If a health check succeeds within the startPeriod , then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
systemControls (list) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run .
Note
It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. For tasks that use the awsvpc network mode, the container that is started last determines which systemControls parameters take effect. For tasks that use the host network mode, it changes the container instance's namespaced kernel parameters as well as the containers.
(dict) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run .
It is not recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network mode for the following reasons:
namespace (string) --
The namespaced kernel parameter for which to set a value .
value (string) --
The value for the namespaced kernel parameter specified in namespace .
resourceRequirements (list) --
The type and amount of a resource to assign to a container. The only supported resource is a GPU.
(dict) --
The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see Working with GPUs on Amazon ECS or Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide
value (string) --
The value for the specified resource type.
If the GPU type is used, the value is the number of physical GPUs the Amazon ECS container agent will reserve for the container. The number of GPUs reserved for all containers in a task should not exceed the number of available GPUs on the container instance the task is launched on.
If the InferenceAccelerator type is used, the value should match the deviceName for an InferenceAccelerator specified in a task definition.
type (string) --
The type of resource to assign to a container. The supported values are GPU or InferenceAccelerator .
firelensConfiguration (dict) --
The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide .
type (string) --
The log router to use. The valid values are fluentd or fluentbit .
options (dict) --
The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"} . For more information, see Creating a Task Definition that Uses a FireLens Configuration in the Amazon Elastic Container Service Developer Guide .
Note
Tasks hosted on Fargate only support the file configuration file type.
family (string) --
The name of a family that this task definition is registered to. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
taskRoleArn (string) --
The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide .
IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code in order to take advantage of the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide .
executionRoleArn (string) --
The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide .
networkMode (string) --
The Docker networking mode to use for the containers in the task. The valid values are none , bridge , awsvpc , and host . If no network mode is specified, the default is bridge .
For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none , you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.
With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.
Warning
When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.
If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .
If the network mode is host , you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.
For more information, see Network settings in the Docker run reference .
revision (integer) --
The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is 1 . Each time that you register a new revision of a task definition in the same family, the revision value always increases by one, even if you have deregistered previous revisions in this family.
volumes (list) --
The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide .
Note
The host and sourcePath parameters are not supported for tasks run on Fargate.
(dict) --
A data volume used in a task definition. For tasks that use the Amazon Elastic File System (Amazon EFS), specify an efsVolumeConfiguration . For Windows tasks that use Amazon FSx for Windows File Server file system, specify a fsxWindowsFileServerVolumeConfiguration . For tasks that use a Docker volume, specify a DockerVolumeConfiguration . For tasks that use a bind mount host volume, specify a host and optional sourcePath . For more information, see Using Data Volumes in Tasks .
name (string) --
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints .
host (dict) --
This parameter is specified when you are using bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data is not guaranteed to persist after the containers associated with it stop running.
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers cannot mount directories on a different drive, and mount point cannot be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\ , but not D:\my\path:C:\my\path or D:\:C:\my\path .
sourcePath (string) --
When the host parameter is used, specify a sourcePath to declare the path on the host container instance that is presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value does not exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
If you are using the Fargate launch type, the sourcePath parameter is not supported.
dockerVolumeConfiguration (dict) --
This parameter is specified when you are using Docker volumes.
Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.
Note
Docker volumes are not supported by tasks run on Fargate.
scope (string) --
The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.
autoprovision (boolean) --
If this value is true , the Docker volume is created if it does not already exist.
Note
This field is only used if the scope is shared .
driver (string) --
The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. For more information, see Docker plugin discovery . This parameter maps to Driver in the Create a volume section of the Docker Remote API and the xxdriver option to docker volume create .
driverOpts (dict) --
A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the Create a volume section of the Docker Remote API and the xxopt option to docker volume create .
labels (dict) --
Custom metadata to add to your Docker volume. This parameter maps to Labels in the Create a volume section of the Docker Remote API and the xxlabel option to docker volume create .

This parameter is specified when you are using an Amazon Elastic File System file system for task storage.
fileSystemId (string) --
The Amazon EFS file system ID to use.
rootDirectory (string) --
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.
transitEncryption (string) --
Whether or not to enable encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be enabled if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting Data in Transit in the Amazon Elastic File System User Guide .
transitEncryptionPort (integer) --
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS Mount Helper in the Amazon Elastic File System User Guide .
authorizationConfig (dict) --
The authorization configuration details for the Amazon EFS file system.
accessPointId (string) --
The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be enabled in the EFSVolumeConfiguration . For more information, see Working with Amazon EFS Access Points in the Amazon Elastic File System User Guide .
iam (string) --
Whether or not to use the Amazon ECS task IAM role defined in a task definition when mounting the Amazon EFS file system. If enabled, transit encryption must be enabled in the EFSVolumeConfiguration . If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS Access Points in the Amazon Elastic Container Service Developer Guide .

domain (string) --
A fully qualified domain name hosted by an Directory Service Managed Microsoft AD (Active Directory) or self-hosted AD on Amazon EC2.
status (string) --
The status of the task definition.
requiresAttributes (list) --
The container instance attributes required by your task. When an Amazon EC2 instance is registered to your cluster, the Amazon ECS container agent assigns some standard attributes to the instance. You can apply custom attributes, specified as key-value pairs using the Amazon ECS console or the PutAttributes API. These attributes are used when considering task placement for tasks hosted on Amazon EC2 instances. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .
Note
This parameter is not supported for tasks run on Fargate.

compatibilities (list) --
The task launch types the task definition validated against during task definition registration. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
requiresCompatibilities (list) --
The task launch types the task definition was validated against. To determine which task launch types the task definition is validated for, see the TaskDefinition$compatibilities parameter.
cpu (string) --
The number of cpu units used by the task. If you are using the EC2 launch type, this field is optional and any value can be used. If you are using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of valid values for the memory parameter:
memory (string) --
The amount (in MiB) of memory used by the task.
If your tasks will be run on Amazon EC2 instances, you must specify either a task-level memory value or a container-level memory value. This field is optional and any value can be used. If a task-level memory value is specified then the container-level memory value is optional. For more information regarding container-level memory and memory reservation, see ContainerDefinition .
If your tasks will be run on Fargate, this field is required and you must use one of the following values, which determines your range of valid values for the cpu parameter:

deviceType (string) --
The Elastic Inference accelerator type to use.
pidMode (string) --
The process namespace to use for the containers in the task. The valid values are host or task . If host is specified, then all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same process namespace. If no value is specified, the default is a private namespace. For more information, see PID settings in the Docker run reference .
If the host PID mode is used, be aware that there is a heightened risk of undesired process namespace expose. For more information, see Docker security .
Note
This parameter is not supported for Windows containers or tasks run on Fargate.
ipcMode (string) --
The IPC resource namespace to use for the containers in the task. The valid values are host , task , or none . If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference .
If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security .
If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide .

You can allow Amazon ECS to place tasks for you, or you can customize how Amazon ECS places tasks using placement constraints and placement strategies. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide .
Alternatively, you can use StartTask to use your own scheduler or place tasks manually on specific container instances.
The Amazon ECS API follows an eventual consistency model, due to the distributed nature of the system supporting the API. This means that the result of an API command you run that affects your Amazon ECS resources might not be immediately visible to all subsequent commands you run. Keep this in mind when you carry out an API command that immediately follows a previous API command.
To manage eventual consistency, you can do the following:

The capacity provider strategy to use for the task.
If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.
When you use cluster auto scaling, you must specify capacityProviderStrategy and not launchType .
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
The short name of the capacity provider.
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
The infrastructure on which to run your standalone task. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
The FARGATE launch type runs your tasks on Fargate On-Demand infrastructure.
Note
Fargate Spot infrastructure is available for use but a capacity provider strategy must be used. For more information, see Fargate capacity providers in the Amazon ECS User Guide for Fargate .
The EC2 launch type runs your tasks on Amazon EC2 instances registered to your cluster.
The EXTERNAL launch type runs your tasks on your on-premise server or virtual machine (VM) capacity registered to your cluster.
A task can use either a launch type or a capacity provider strategy. If a launchType is specified, the capacityProviderStrategy parameter must be omitted.
When you use cluster auto scaling, you must specify capacityProviderStrategy and not launchType .

For more information on the environment variable file syntax, see Declare default environment variables in file .
If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they are processed from the top down. It is recommended to use unique variable names. For more information, see Specifying environment variables in the Amazon Elastic Container Service Developer Guide .
This field is only valid for containers in Fargate tasks that use platform version 1.4.0 or later.
The Amazon Resource Name (ARN) of the Amazon S3 object containing the environment variable file.
The file type to use. The only supported value is s3 .
The number of cpu units reserved for the container, instead of the default value from the task definition. You must also specify a container name.
The hard limit (in MiB) of memory to present to the container, instead of the default value from the task definition. If your container attempts to exceed the memory specified here, the container is killed. You must also specify a container name.

A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is distinctInstance . For more information, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide .
The placement strategy objects to use for the task. You can specify a maximum of five strategy rules per task.
The task placement strategy for a task or service. For more information, see Task Placement Strategies in the Amazon Elastic Container Service Developer Guide .
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that is specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory (but still enough to run the task).
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
Specifies whether to propagate the tags from the task definition to the task. If no value is specified, the tags are not propagated. Tags can only be propagated to the task during task creation. To add tags to a task after task creation, use the TagResource API action.
Note
An error will be received if you specify the SERVICE option when running a task.
An optional tag specified when a task is started. For example, if you automatically trigger a task to run a batch process job, you could apply a unique identifier for that job to your task with the startedBy parameter. You can then identify which tasks belong to that job by filtering the results of a ListTasks call with the startedBy value. Up to 36 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.
If a task is started by an Amazon ECS service, then the startedBy parameter contains the deployment ID of the service that starts it.
The metadata that you apply to the task to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:

The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
taskArn (string) --
The Amazon Resource Name (ARN) of the task.
taskDefinitionArn (string) --
The ARN of the task definition that creates the task.
version (integer) --
The version counter for the task. Every time a task experiences a change that triggers a CloudWatch event, the version counter is incremented. If you are replicating your Amazon ECS task state with CloudWatch Events, you can compare the version of a task reported by the Amazon ECS API actions with the version reported in CloudWatch Events for the task (inside the detail object) to verify that the version in your event stream is current.
ephemeralStorage (dict) --
The ephemeral storage settings for the task.
sizeInGiB (integer) --
The total amount, in GiB, of ephemeral storage to set for the task. The minimum supported value is 21 GiB and the maximum supported value is 200 GiB.
failures (list) --
Any failures associated with the call.
(dict) --
A failed resource. For a list of common causes, see API failure reasons in the Amazon Elastic Container Service Developer Guide .
arn (string) --
The Amazon Resource Name (ARN) of the failed resource.
reason (string) --
The reason for the failure.
detail (string) --
The details of the failure.
Exceptions
Stops a running task. Any tags associated with the task will be deleted.
When StopTask is called on a task, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM value and a default 30-second timeout, after which the SIGKILL value is sent and the containers are forcibly stopped. If the container handles the SIGTERM value gracefully and exits within 30 seconds from receiving it, no SIGKILL value is sent.
Note
The default 30-second timeout can be configured on the Amazon ECS container agent with the ECS_CONTAINER_STOP_TIMEOUT variable. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .

The period of time, in seconds, after a newly launched Amazon EC2 instance can contribute to CloudWatch metrics for Auto Scaling group. If this parameter is omitted, the default value of 300 seconds is used.
The managed termination protection setting to use for the Auto Scaling group capacity provider. This determines whether the Auto Scaling group has managed termination protection.
Warning
When using managed termination protection, managed scaling must also be used otherwise managed termination protection will not work.
When managed termination protection is enabled, Amazon ECS prevents the Amazon EC2 instances in an Auto Scaling group that contain tasks from being terminated during a scale-in action. The Auto Scaling group and each instance in the Auto Scaling group must have instance protection from scale-in actions enabled as well. For more information, see Instance Protection in the Auto Scaling User Guide .
When managed termination protection is disabled, your Amazon EC2 instances are not protected from termination when the Auto Scaling group scales in.

INACTIVE
The cluster has been deleted. Clusters with an INACTIVE status may remain discoverable in your account for a period of time. However, this behavior is subject to change in the future, so you should not rely on INACTIVE clusters persisting.
registeredContainerInstancesCount (integer) --
The number of container instances registered into the cluster. This includes container instances in both ACTIVE and DRAINING status.
runningTasksCount (integer) --
The number of tasks in the cluster that are in the RUNNING state.
pendingTasksCount (integer) --
The number of tasks in the cluster that are in the PENDING state.

If enabled is specified, CloudWatch Container Insights will be enabled for the cluster, otherwise it will be disabled unless the containerInsights account setting is enabled. If a cluster value is specified, it will override the containerInsights value set with PutAccountSetting or PutAccountSettingDefault .
capacityProviders (list) --
The capacity providers associated with the cluster.
defaultCapacityProviderStrategy (list) --
The default capacity provider strategy for the cluster. When services or tasks are run in the cluster with no launch type or capacity provider strategy specified, the default capacity provider strategy is used.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent does not interrupt running tasks or services on the container instance. The process for updating the agent differs depending on whether your container instance was launched with the Amazon ECS-optimized AMI or another operating system.
Note
The UpdateContainerAgent API isn't supported for container instances using the Amazon ECS-optimized Amazon Linux 2 (arm64) AMI. To update the container agent, you can update the ecs-init package which will update the agent. For more information, see Updating the Amazon ECS container agent in the Amazon Elastic Container Service Developer Guide .
The UpdateContainerAgent API requires an Amazon ECS-optimized AMI or Amazon Linux AMI with the ecs-init service installed and running.

Exceptions
Modifies the status of an Amazon ECS container instance.
Once a container instance has reached an ACTIVE state, you can change the status of a container instance to DRAINING to manually remove an instance from a cluster, for example to perform system updates, update the Docker daemon, or scale down the cluster size.
Warning
A container instance cannot be changed to DRAINING until it has reached an ACTIVE status. If the instance is in any other status, an error will be received.
When you set a container instance to DRAINING , Amazon ECS prevents new tasks from being scheduled for placement on the container instance and replacement service tasks are started on other container instances in the cluster if the resources are available. Service tasks on the container instance that are in the PENDING state are stopped immediately.
Service tasks on the container instance that are in the RUNNING state are stopped and replaced according to the service's deployment configuration parameters, minimumHealthyPercent and maximumPercent . You can change the deployment configuration of your service using UpdateService .
Any PENDING or RUNNING tasks that do not belong to a service are not affected. You must wait for them to finish or stop them manually.
A container instance has completed draining when it has no more RUNNING tasks. You can verify this using ListTasks .
When a container instance has been drained, you can set a container instance to ACTIVE status and once it has reached that status the Amazon ECS scheduler can begin scheduling tasks on the instance again.

Warning
Updating the task placement strategies and constraints on an Amazon ECS service remains in preview and is a Beta Service as defined by and subject to the Beta Service Participation Service Terms located at https://aws.amazon.com/service-terms ("Beta Terms"). These Beta Terms apply to your participation in this preview.
Modifies the parameters of a service.
For services using the rolling update (ECS ) deployment controller, the desired count, deployment configuration, network configuration, task placement constraints and strategies, or task definition used can be updated.
For services using the blue/green (CODE_DEPLOY ) deployment controller, only the desired count, deployment configuration, task placement constraints and strategies, and health check grace period can be updated using this API. If the network configuration, platform version, or task definition need to be updated, a new CodeDeploy deployment should be created. For more information, see CreateDeployment in the CodeDeploy API Reference .
For services using an external deployment controller, you can update only the desired count, task placement constraints and strategies, and health check grace period using this API. If the launch type, load balancer, network configuration, platform version, or task definition need to be updated, you should create a new task set. For more information, see CreateTaskSet .
You can add to or subtract from the number of instantiations of a task definition in a service by specifying the cluster that the service is running in and a new desiredCount parameter.
If you have updated the Docker image of your application, you can create a new task definition with that image and deploy it to your service. The service scheduler uses the minimum healthy percent and maximum percent parameters (in the service's deployment configuration) to determine the deployment strategy.
Note
If your updated Docker image uses the same tag as what is in the existing task definition for your service (for example, my_image:latest ), you do not need to create a new revision of your task definition. You can update the service using the forceNewDeployment option. The new tasks launched by the deployment pull the current image/tag combination from your repository when they start.
You can also update the deployment configuration of a service. When a deployment is triggered by updating the task definition of a service, the service scheduler uses the deployment configuration parameters, minimumHealthyPercent and maximumPercent , to determine the deployment strategy.
When UpdateService stops a task during a deployment, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM and a 30-second timeout, after which SIGKILL is sent and the containers are forcibly stopped. If the container handles the SIGTERM gracefully and exits within 30 seconds from receiving it, no SIGKILL is sent.
When the service scheduler launches new tasks, it determines task placement in your cluster with the following logic:
When the service scheduler stops running tasks, it attempts to maintain balance across the Availability Zones in your cluster using the following logic:

[REQUIRED]
The name of the service to update.
The capacity provider strategy to update the service to use.
If the service is using the default capacity provider strategy for the cluster, the service can be updated to use one or more capacity providers as opposed to the default capacity provider strategy. However, when a service is using a capacity provider strategy that is not the default capacity provider strategy, the service cannot be updated to use the cluster's default capacity provider strategy.
A capacity provider strategy consists of one or more capacity providers along with the base and weight to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with an ACTIVE or UPDATING status can be used.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.
The PutClusterCapacityProviders API operation is used to update the list of available capacity providers for a cluster after the cluster is created.
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
The short name of the capacity provider.
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
Note
The deployment circuit breaker can only be used for services using the rolling update (ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If deployment circuit breaker is enabled, a service deployment will transition to a failed state and stop launching new tasks. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
Whether to enable the deployment circuit breaker logic for the service.
Whether to enable Amazon ECS to roll back the service if a service deployment fails. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
If a service is using the rolling update (ECS ) deployment type, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
If a service is using the rolling update (ECS ) deployment type, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in the RUNNING state during a deployment, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.
An object representing the network configuration for the service.
The VPC subnets and security groups associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
The IDs of the subnets associated with the task or service. There is a limit of 16 subnets that can be specified per AwsVpcConfiguration .
Note
All specified subnets must be from the same VPC.
The IDs of the security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
An array of task placement constraint objects to update the service to use. If no value is specified, the existing placement constraints for the service will remain unchanged. If this value is specified, it will override any existing placement constraints defined for the service. To remove all existing placement constraints, specify an empty array.
You can specify a maximum of 10 constraints per task (this limit includes constraints in the task definition and those specified at runtime).
An object representing a constraint on task placement. For more information, see Task Placement Constraints in the Amazon Elastic Container Service Developer Guide .
Note
If you are using the Fargate launch type, task placement constraints are not supported.
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is distinctInstance . For more information, see Cluster Query Language in the Amazon Elastic Container Service Developer Guide .
The task placement strategy objects to update the service to use. If no value is specified, the existing placement strategy for the service will remain unchanged. If this value is specified, it will override the existing placement strategy defined for the service. To remove an existing placement strategy, specify an empty object.
You can specify a maximum of five strategy rules per service.
The task placement strategy for a task or service. For more information, see Task Placement Strategies in the Amazon Elastic Container Service Developer Guide .
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that is specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory (but still enough to run the task).
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
If true , this enables execute command functionality on all task containers.
If you do not want to override the value that was set when the service was created, you can set this to null when performing this action.

Response Structure
(dict) --
service (dict) --
The full description of your service following the update call.
serviceArn (string) --
The ARN that identifies the service. The ARN contains the arn:aws:ecs namespace, followed by the Region of the service, the account ID of the service owner, the service namespace, and then the service name. For example, arn:aws:ecs:region:012345678910:service/my-service .
serviceName (string) --
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that hosts the service.
loadBalancers (list) --
A list of Elastic Load Balancing load balancer objects, containing the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer.
(dict) --
The load balancer configuration to use with a service or task set.
For specific notes and restrictions regarding the use of load balancers with services and task sets, see the CreateService and CreateTaskSet actions.
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they are launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details of the service discovery registries to assign to this service. For more information, see Service Discovery .
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .
port (integer) --
The port value used if your service discovery service specified an SRV record. This field may be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
status (string) --
The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .
desiredCount (integer) --
The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .
runningCount (integer) --
The number of tasks in the cluster that are in the RUNNING state.
pendingCount (integer) --
The number of tasks in the cluster that are in the PENDING state.
launchType (string) --
The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.
capacityProviderStrategy (list) --
The capacity provider strategy the service is using. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --
The platform version on which to run your service. A platform version is only specified for tasks hosted on Fargate. If one is not specified, the LATEST platform version is used by default. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
taskDefinition (string) --
The task definition to use for tasks in the service. This value is specified when the service is created with CreateService , and it can be modified with UpdateService .
deploymentConfiguration (dict) --
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker (dict) --
Note
The deployment circuit breaker can only be used for services using the rolling update (ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If deployment circuit breaker is enabled, a service deployment will transition to a failed state and stop launching new tasks. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
enable (boolean) --
Whether to enable the deployment circuit breaker logic for the service.
rollback (boolean) --
Whether to enable Amazon ECS to roll back the service if a service deployment fails. If rollback is enabled, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent (integer) --
If a service is using the rolling update (ECS ) deployment type, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimumHealthyPercent (integer) --
If a service is using the rolling update (ECS ) deployment type, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in the RUNNING state during a deployment, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green (CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

externalId (string) --
The external ID associated with the task set.
If a task set is created by an CodeDeploy deployment, the externalId parameter contains the CodeDeploy deployment ID.
If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.
status (string) --
The status of the task set. The following describes each state:
PRIMARY

taskDefinition (string) --
The task definition the task set is using.
computedDesiredCount (integer) --
The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.

The capacity provider strategy associated with the task set.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --

When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 will not be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that is run using capacityProviderA , four tasks would use capacityProviderB .

A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer the target group ARN should be omitted.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering Multiple Target Groups with a Service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.

For services using the CODE_DEPLOY deployment controller, you are required to define two target groups for the load balancer. For more information, see Blue/Green Deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode (which is required for the Fargate launch type), you must choose ip as the target type, not instance , when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they are launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details of the service discovery registries to assign to this task set. For more information, see Service discovery .
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService .
port (integer) --
The port value used if your service discovery service specified an SRV record. This field may be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value, but not both.
scale (dict) --
A floating-point percentage of the desired number of tasks to place and keep running in the task set.
value (float) --
The value, specified as a percent total of a service's desiredCount , to scale the task set. Accepted values are numbers between 0 and 100.
unit (string) --
The unit of measure for the scale value.
stabilityStatus (string) --
The stability status, which indicates whether the task set has reached a steady state. If the following conditions are met, the task set will be in STEADY_STATE :
If any of those conditions are not met, the stability status returns STABILIZING .
stabilityStatusAt (datetime) --
The Unix timestamp for when the task set stability status was retrieved.
tags (list) --
The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
(dict) --
The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.
The following basic restrictions apply to tags:
key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

The task desired status to use when filtering the ListTasks results. Specifying a desiredStatus of STOPPED limits the results to tasks that Amazon ECS has set the desired status to STOPPED . This can be useful for debugging tasks that are not starting properly or have died or finished. The default status filter is RUNNING , which shows tasks that Amazon ECS has set the desired status to RUNNING .
Note
Although you can filter results based on a desired status of PENDING , this does not return any results. Amazon ECS never sets the desired status of a task to that value (only a task's lastStatus may have a value of PENDING ).
