Batch.Client¶A low-level client representing AWS Batch
Using Batch, you can run batch computing workloads on the Amazon Web Services Cloud. Batch computing is a common means for developers, scientists, and engineers to access large amounts of compute resources. Batch uses the advantages of the batch computing to remove the undifferentiated heavy lifting of configuring and managing required infrastructure. At the same time, it also adopts a familiar batch computing software approach. You can use Batch to efficiently provision resources d, and work toward eliminating capacity constraints, reducing your overall compute costs, and delivering results more quickly.
As a fully managed service, Batch can run batch computing workloads of any scale. Batch automatically provisions compute resources and optimizes workload distribution based on the quantity and scale of your specific workloads. With Batch, there's no need to install or manage batch computing software. This means that you can focus on analyzing results and solving your specific problems instead.

create_compute_environment(**kwargs)¶Creates an Batch compute environment. You can create MANAGED or UNMANAGED compute environments. MANAGED compute environments can use Amazon EC2 or Fargate resources. UNMANAGED compute environments can only use EC2 resources.
In a managed compute environment, Batch manages the capacity and instance types of the compute resources within the environment. This is based on the compute resource specification that you define or the launch template that you specify when you create the compute environment. Either, you can choose to use EC2 On-Demand Instances and EC2 Spot Instances. Or, you can use Fargate and Fargate Spot capacity in your managed compute environment. You can optionally set a maximum price so that Spot Instances only launch when the Spot Instance price is less than a specified percentage of the On-Demand price.
Note
Multi-node parallel jobs aren't supported on Spot Instances.
In an unmanaged compute environment, you can manage your own EC2 compute resources and have flexibility with how you configure your compute resources. For example, you can use custom AMIs. However, you must verify that each of your AMIs meet the Amazon ECS container instance AMI specification. For more information, see container instance AMIs in the Amazon Elastic Container Service Developer Guide . After you created your unmanaged compute environment, you can use the DescribeComputeEnvironments operation to find the Amazon ECS cluster that's associated with it. Then, launch your container instances into that Amazon ECS cluster. For more information, see Launching an Amazon ECS container instance in the Amazon Elastic Container Service Developer Guide .
Note
Batch doesn't automatically upgrade the AMIs in a compute environment after it's created. For example, it also doesn't update the AMIs in your compute environment when a newer version of the Amazon ECS optimized AMI is available. You're responsible for the management of the guest operating system. This includes any updates and security patches. You're also responsible for any additional application software or utilities that you install on the compute resources. There are two ways to use a new AMI for your Batch jobs. The original method is to complete these steps:
In April 2022, Batch added enhanced support for updating compute environments. For more information, see Updating compute environments . To use the enhanced updating of compute environments to update AMIs, follow these rules:
serviceRole ) parameter or set it to the AWSBatchServiceRole service-linked role.allocationStrategy ) parameter to BEST_FIT_PROGRESSIVE or SPOT_CAPACITY_OPTIMIZED .updateToLatestImageVersion ) parameter to true .imageId , imageIdOverride (in ` ec2Configuration https://docs.aws.amazon.com/batch/latest/APIReference/API_Ec2Configuration.html`__ ), or in the launch template (launchTemplate ). In that case, Batch selects the latest Amazon ECS optimized AMI that's supported by Batch at the time the infrastructure update is initiated. Alternatively, you can specify the AMI ID in the imageId or imageIdOverride parameters, or the launch template identified by the LaunchTemplate properties. Changing any of these properties starts an infrastructure update. If the AMI ID is specified in the launch template, it can't be replaced by specifying an AMI ID in either the imageId or imageIdOverride parameters. It can only be replaced by specifying a different launch template, or if the launch template version is set to $Default or $Latest , by setting either a new default version for the launch template (if $Default ) or by adding a new version to the launch template (if $Latest ).If these rules are followed, any update that starts an infrastructure update causes the AMI ID to be re-selected. If the version setting in the launch template (launchTemplate ) is set to $Latest or $Default , the latest or default version of the launch template is evaluated up at the time of the infrastructure update, even if the launchTemplate wasn't updated.

[REQUIRED]
The name for your compute environment. It can be up to 128 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).
[REQUIRED]
The type of the compute environment: MANAGED or UNMANAGED . For more information, see Compute Environments in the Batch User Guide .
The state of the compute environment. If the state is ENABLED , then the compute environment accepts jobs from a queue and can scale out automatically based on queues.
If the state is ENABLED , then the Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically, based on the job queue demand.
If the state is DISABLED , then the Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out. However, they scale in to minvCpus value after instances become idle.
The maximum number of vCPUs for an unmanaged compute environment. This parameter is only used for fair share scheduling to reserve vCPU capacity for new share identifiers. If this parameter isn't provided for a fair share job queue, no vCPU capacity is reserved.
Note
This parameter is only supported when the type parameter is set to UNMANAGED .
Details about the compute resources managed by the compute environment. This parameter is required for managed compute environments. For more information, see Compute Environments in the Batch User Guide .
The type of compute environment: EC2 , SPOT , FARGATE , or FARGATE_SPOT . For more information, see Compute environments in the Batch User Guide .
If you choose SPOT , you must also specify an Amazon EC2 Spot Fleet role with the spotIamFleetRole parameter. For more information, see Amazon EC2 spot fleet role in the Batch User Guide .
The allocation strategy to use for the compute resource if not enough instances of the best fitting instance type can be allocated. This might be because of availability of the instance type in the Region or Amazon EC2 service limits . For more information, see Allocation strategies in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
BEST_FIT (default)
Batch selects an instance type that best fits the needs of the jobs with a preference for the lowest-cost instance type. If additional instances of the selected instance type aren't available, Batch waits for the additional instances to be available. If there aren't enough instances available or the user is reaching Amazon EC2 service limits , additional jobs aren't run until the currently running jobs are completed. This allocation strategy keeps costs lower but can limit scaling. If you're using Spot Fleets with BEST_FIT , the Spot Fleet IAM Role must be specified. Compute resources that use a BEST_FIT allocation strategy don't support infrastructure updates and can't update some parameters. For more information, see Updating compute environments in the Batch User Guide .
BEST_FIT_PROGRESSIVE
Batch selects additional instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types with lower cost vCPUs. If additional instances of the previously selected instance types aren't available, Batch selects new instance types.
SPOT_CAPACITY_OPTIMIZED
Batch selects one or more instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.
With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.
The minimum number of Amazon EC2 vCPUs that an environment should maintain (even if the compute environment is DISABLED ).
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The maximum number of Amazon EC2 vCPUs that a compute environment can reach.
Note
With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance. For example, no more than a single instance from among those specified in your compute environment is allocated.
The desired number of Amazon EC2 vCPUS in the compute environment. Batch modifies this value between the minimum and maximum values based on job queue demand.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The instances types that can be launched. You can specify instance families to launch any instance type within those families (for example, c5 or p3 ), or you can specify specific sizes within a family (such as c5.8xlarge ). You can also choose optimal to select instance types (from the C4, M4, and R4 instance families) that match the demand of your job queues.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Note
When you create a compute environment, the instance types that you select for the compute environment must share the same architecture. For example, you can't mix x86 and ARM instances in the same compute environment.
Note
Currently, optimal uses instance types from the C4, M4, and R4 instance families. In Regions that don't have instance types from those instance families, instance types from the C5, M5, and R5 instance families are used.
The Amazon Machine Image (AMI) ID used for instances launched in the compute environment. This parameter is overridden by the imageIdOverride member of the Ec2Configuration structure.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Note
The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide .
The VPC subnets where the compute resources are launched. These subnets must be within the same VPC. Fargate compute resources can contain up to 16 subnets. For more information, see VPCs and subnets in the Amazon VPC User Guide .
The Amazon EC2 security groups that are associated with instances launched in the compute environment. One or more security groups must be specified, either in securityGroupIds or using a launch template referenced in launchTemplate . This parameter is required for jobs that are running on Fargate resources and must contain at least one security group. Fargate doesn't support launch templates. If security groups are specified using both securityGroupIds and launchTemplate , the values in securityGroupIds are used.
The Amazon EC2 key pair that's used for instances launched in the compute environment. You can use this key pair to log in to your instances with SSH.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The Amazon ECS instance profile applied to Amazon EC2 instances in a compute environment. You can specify the short name or full Amazon Resource Name (ARN) of an instance profile. For example, `` ecsInstanceRole `` or ``arn:aws:iam::<aws_account_id> :instance-profile/ecsInstanceRole `` . For more information, see Amazon ECS instance role in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Key-value pair tags to be applied to EC2 resources that are launched in the compute environment. For Batch, these take the form of "String1": "String2" , where String1 is the tag key and String2 is the tag value-for example, { "Name": "Batch Instance - C4OnDemand" } . This is helpful for recognizing your Batch instances in the Amazon EC2 console. Updating these tags requires an infrastructure update to the compute environment. For more information, see Updating compute environments in the Batch User Guide . These tags aren't seen when using the Batch ListTagsForResource API operation.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The Amazon EC2 placement group to associate with your compute resources. If you intend to submit multi-node parallel jobs to your compute environment, you should consider creating a cluster placement group and associate it with your compute resources. This keeps your multi-node parallel job on a logical grouping of instances within a single Availability Zone with high network flow potential. For more information, see Placement groups in the Amazon EC2 User Guide for Linux Instances .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, then the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage. If you leave this field empty, the default value is 100% of the On-Demand price.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The Amazon Resource Name (ARN) of the Amazon EC2 Spot Fleet IAM role applied to a SPOT compute environment. This role is required if the allocation strategy set to BEST_FIT or if the allocation strategy isn't specified. For more information, see Amazon EC2 spot fleet role in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Warning
To tag your Spot Instances on creation, the Spot Fleet IAM role specified here must use the newer AmazonEC2SpotFleetTaggingRole managed policy. The previously recommended AmazonEC2SpotFleetRole managed policy doesn't have the required permissions to tag Spot Instances. For more information, see Spot instances not tagged on creation in the Batch User Guide .
The launch template to use for your compute resources. Any other compute resource parameters that you specify in a CreateComputeEnvironment API operation override the same parameters in the launch template. You must specify either the launch template ID or launch template name in the request, but not both. For more information, see Launch template support in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The ID of the launch template.
The name of the launch template.
The version number of the launch template, $Latest , or $Default .
If the value is $Latest , the latest version of the launch template is used. If the value is $Default , the default version of the launch template is used.
Warning
If the AMI ID that's used in a compute environment is from the launch template, the AMI isn't changed when the compute environment is updated. It's only changed if the updateToLatestImageVersion parameter for the compute environment is set to true . During an infrastructure update, if either $Latest or $Default is specified, Batch re-evaluates the launch template version, and it might use a different version of the launch template. This is the case even if the launch template isn't specified in the update. When updating a compute environment, changing the launch template requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Default: $Default .
Provides information that's used to select Amazon Machine Images (AMIs) for EC2 instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL2 .
One or two values can be provided.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Provides information used to select Amazon Machine Images (AMIs) for instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL2 (Amazon Linux 2 ).
Note
This object isn't applicable to jobs that are running on Fargate resources.
The image type to match with the instance type to select an AMI. The supported values are different for ECS and EKS resources.
ECS
If the imageIdOverride parameter isn't specified, then a recent Amazon ECS-optimized Amazon Linux 2 AMI (ECS_AL2 ) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon ECS optimized AMI for that image type that's supported by Batch is used.
ECS_AL2Amazon Linux 2 : Default for all non-GPU instance families.
ECS_AL2_NVIDIAAmazon Linux 2 (GPU) : Default for all GPU instance families (for example
P4andG4) and can be used for all non Amazon Web Services Graviton-based instance types.ECS_AL1Amazon Linux . Amazon Linux has reached the end-of-life of standard support. For more information, see Amazon Linux AMI .
EKS
If the imageIdOverride parameter isn't specified, then a recent Amazon EKS-optimized Amazon Linux AMI (EKS_AL2 ) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon EKS optimized AMI for that image type that Batch supports is used.
EKS_AL2Amazon Linux 2 : Default for all non-GPU instance families.
EKS_AL2_NVIDIAAmazon Linux 2 (accelerated) : Default for all GPU instance families (for example,
P4andG4) and can be used for all non Amazon Web Services Graviton-based instance types.
The AMI ID used for instances launched in the compute environment that match the image type. This setting overrides the imageId set in the computeResource object.
Note
The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide .
The Kubernetes version for the compute environment. If you don't specify a value, the latest version that Batch supports is used.
The full Amazon Resource Name (ARN) of the IAM role that allows Batch to make calls to other Amazon Web Services services on your behalf. For more information, see Batch service IAM role in the Batch User Guide .
Warning
If your account already created the Batch service-linked role, that role is used by default for your compute environment unless you specify a different role here. If the Batch service-linked role doesn't exist in your account, and no role is specified here, the service attempts to create the Batch service-linked role in your account.
If your specified role has a path other than / , then you must specify either the full role ARN (recommended) or prefix the role name with the path. For example, if a role with the name bar has a path of /foo/ , specify /foo/bar as the role name. For more information, see Friendly names and paths in the IAM User Guide .
Note
Depending on how you created your Batch service role, its ARN might contain the service-role path prefix. When you only specify the name of the service role, Batch assumes that your ARN doesn't use the service-role path prefix. Because of this, we recommend that you specify the full ARN of your service role when you create compute environments.
The tags that you apply to the compute environment to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging Amazon Web Services Resources in Amazon Web Services General Reference .
These tags can be updated or removed using the TagResource and UntagResource API operations. These tags don't propagate to the underlying compute resources.
The details for the Amazon EKS cluster that supports the compute environment.
The Amazon Resource Name (ARN) of the Amazon EKS cluster. An example is ``arn:aws :eks:us-east-1 :123456789012 :cluster/ClusterForBatch `` .
The namespace of the Amazon EKS cluster. Batch manages pods in this namespace. The value can't left empty or null. It must be fewer than 64 characters long, can't be set to default , can't start with "kube- ," and must match this regular expression: ^[a-z0-9]([-a-z0-9]*[a-z0-9])?$ . For more information, see Namespaces in the Kubernetes documentation.

create_job_queue(**kwargs)¶Creates an Batch job queue. When you create a job queue, you associate one or more compute environments to the queue and assign an order of preference for the compute environments.
You also set a priority to the job queue that determines the order that the Batch scheduler places jobs onto its associated compute environments. For example, if a compute environment is associated with more than one job queue, the job queue with a higher priority is given preference for scheduling jobs to that compute environment.

The name of the job queue. It can be up to 128 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).
ENABLED , it is able to accept jobs. If the job queue state is DISABLED , new jobs can't be added to the queue, but jobs already in the queue can finish.aws:*Partition* :batch:*Region* :*Account* :scheduling-policy/*Name* `` . An example is ``aws:aws:batch:us-west-2:123456789012:scheduling-policy/MySchedulingPolicy .[REQUIRED]
The priority of the job queue. Job queues with a higher priority (or a higher integer value for the priority parameter) are evaluated first when associated with the same compute environment. Priority is determined in descending order. For example, a job queue with a priority value of 10 is given scheduling preference over a job queue with a priority value of 1 . All of the compute environments must be either EC2 (EC2 or SPOT ) or Fargate (FARGATE or FARGATE_SPOT ); EC2 and Fargate compute environments can't be mixed.
[REQUIRED]
The set of compute environments mapped to a job queue and their order relative to each other. The job scheduler uses this parameter to determine which compute environment runs a specific job. Compute environments must be in the VALID state before you can associate them with a job queue. You can associate up to three compute environments with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT ) or Fargate (FARGATE or FARGATE_SPOT ); EC2 and Fargate compute environments can't be mixed.
Note
All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.
The order that compute environments are tried in for job placement within a queue. Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first. Compute environments must be in the VALID state before you can associate them with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT ) or Fargate (FARGATE or FARGATE_SPOT ); EC2 and Fargate compute environments can't be mixed.
Note
All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.
The order of the compute environment. Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first.

)
[REQUIRED]
The name of the scheduling policy. It can be up to 128 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).
The fair share policy of the scheduling policy.
The amount of time (in seconds) to use to calculate a fair share percentage for each fair share identifier in use. A value of zero (0) indicates that only current usage is measured. The decay allows for more recently run jobs to have more weight than jobs that ran earlier. The maximum supported value is 604800 (1 week).
A value used to reserve some of the available maximum vCPU for fair share identifiers that aren't already used.
The reserved ratio is ``(computeReservation /100)^*ActiveFairShares* `` where `` ActiveFairShares `` is the number of active fair share identifiers.
For example, a computeReservation value of 50 indicates that Batchreserves 50% of the maximum available vCPU if there's only one fair share identifier. It reserves 25% if there are two fair share identifiers. It reserves 12.5% if there are three fair share identifiers. A computeReservation value of 25 indicates that Batch should reserve 25% of the maximum available vCPU if there's only one fair share identifier, 6.25% if there are two fair share identifiers, and 1.56% if there are three fair share identifiers.
The minimum value is 0 and the maximum value is 99.
An array of SharedIdentifier objects that contain the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0 .
Specifies the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0 .
A fair share identifier or fair share identifier prefix. If the string ends with an asterisk (*), this entry specifies the weight factor to use for fair share identifiers that start with that prefix. The list of fair share identifiers in a fair share policy can't overlap. For example, you can't have one that specifies a shareIdentifier of UserA* and another that specifies a shareIdentifier of UserA-1 .
There can be no more than 500 fair share identifiers active in a job queue.
The string is limited to 255 alphanumeric characters, and can be followed by an asterisk (*).
The weight factor for the fair share identifier. The default value is 1.0. A lower value has a higher priority for compute resources. For example, jobs that use a share identifier with a weight factor of 0.125 (1/8) get 8 times the compute resources of jobs that use a share identifier with a weight factor of 1.
The smallest supported value is 0.0001, and the largest supported value is 999.9999.
The tags that you apply to the scheduling policy to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging Amazon Web Services Resources in Amazon Web Services General Reference .
These tags can be updated or removed using the TagResource and UntagResource API operations.

Batch.Client.exceptions.ClientExceptionBatch.Client.exceptions.ServerExceptiondelete_compute_environment(**kwargs)¶Deletes an Batch compute environment.
Before you can delete a compute environment, you must set its state to DISABLED with the UpdateComputeEnvironment API operation and disassociate it from any job queues with the UpdateJobQueue API operation. Compute environments that use Fargate resources must terminate all active jobs on that compute environment before deleting the compute environment. If this isn't done, the compute environment enters an invalid state.

Response Structure
(dict) --
computeEnvironments (list) --
The list of compute environments.
(dict) --
An object that represents an Batch compute environment.
computeEnvironmentName (string) --
The name of the compute environment. It can be up to 128 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).
computeEnvironmentArn (string) --
The Amazon Resource Name (ARN) of the compute environment.
unmanagedvCpus (integer) --
The maximum number of VCPUs expected to be used for an unmanaged compute environment.
ecsClusterArn (string) --
The Amazon Resource Name (ARN) of the underlying Amazon ECS cluster that the compute environment uses.
tags (dict) --
The tags applied to the compute environment.
type (string) --
The type of the compute environment: MANAGED or UNMANAGED . For more information, see Compute environments in the Batch User Guide .
state (string) --
The state of the compute environment. The valid values are ENABLED or DISABLED .
If the state is ENABLED , then the Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically based on the job queue demand.
If the state is DISABLED , then the Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out. However, they scale in to minvCpus value after instances become idle.
status (string) --
The current status of the compute environment (for example, CREATING or VALID ).
statusReason (string) --
A short, human-readable string to provide additional details for the current status of the compute environment.
computeResources (dict) --
The compute resources defined for the compute environment. For more information, see Compute environments in the Batch User Guide .
type (string) --
The type of compute environment: EC2 , SPOT , FARGATE , or FARGATE_SPOT . For more information, see Compute environments in the Batch User Guide .
If you choose SPOT , you must also specify an Amazon EC2 Spot Fleet role with the spotIamFleetRole parameter. For more information, see Amazon EC2 spot fleet role in the Batch User Guide .
allocationStrategy (string) --
The allocation strategy to use for the compute resource if not enough instances of the best fitting instance type can be allocated. This might be because of availability of the instance type in the Region or Amazon EC2 service limits . For more information, see Allocation strategies in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
BEST_FIT (default)
Batch selects an instance type that best fits the needs of the jobs with a preference for the lowest-cost instance type. If additional instances of the selected instance type aren't available, Batch waits for the additional instances to be available. If there aren't enough instances available or the user is reaching Amazon EC2 service limits , additional jobs aren't run until the currently running jobs are completed. This allocation strategy keeps costs lower but can limit scaling. If you're using Spot Fleets with BEST_FIT , the Spot Fleet IAM Role must be specified. Compute resources that use a BEST_FIT allocation strategy don't support infrastructure updates and can't update some parameters. For more information, see Updating compute environments in the Batch User Guide .
BEST_FIT_PROGRESSIVE
Batch selects additional instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types with lower cost vCPUs. If additional instances of the previously selected instance types aren't available, Batch selects new instance types.
SPOT_CAPACITY_OPTIMIZED
Batch selects one or more instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.
With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.
minvCpus (integer) --
The minimum number of Amazon EC2 vCPUs that an environment should maintain (even if the compute environment is DISABLED ).
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
maxvCpus (integer) --
The maximum number of Amazon EC2 vCPUs that a compute environment can reach.
Note
With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance. For example, no more than a single instance from among those specified in your compute environment is allocated.
desiredvCpus (integer) --
The desired number of Amazon EC2 vCPUS in the compute environment. Batch modifies this value between the minimum and maximum values based on job queue demand.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
instanceTypes (list) --
The instances types that can be launched. You can specify instance families to launch any instance type within those families (for example, c5 or p3 ), or you can specify specific sizes within a family (such as c5.8xlarge ). You can also choose optimal to select instance types (from the C4, M4, and R4 instance families) that match the demand of your job queues.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Note
When you create a compute environment, the instance types that you select for the compute environment must share the same architecture. For example, you can't mix x86 and ARM instances in the same compute environment.
Note
Currently, optimal uses instance types from the C4, M4, and R4 instance families. In Regions that don't have instance types from those instance families, instance types from the C5, M5, and R5 instance families are used.
imageId (string) --
The Amazon Machine Image (AMI) ID used for instances launched in the compute environment. This parameter is overridden by the imageIdOverride member of the Ec2Configuration structure.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Note
The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide .
subnets (list) --
The VPC subnets where the compute resources are launched. These subnets must be within the same VPC. Fargate compute resources can contain up to 16 subnets. For more information, see VPCs and subnets in the Amazon VPC User Guide .
securityGroupIds (list) --
The Amazon EC2 security groups that are associated with instances launched in the compute environment. One or more security groups must be specified, either in securityGroupIds or using a launch template referenced in launchTemplate . This parameter is required for jobs that are running on Fargate resources and must contain at least one security group. Fargate doesn't support launch templates. If security groups are specified using both securityGroupIds and launchTemplate , the values in securityGroupIds are used.
ec2KeyPair (string) --
The Amazon EC2 key pair that's used for instances launched in the compute environment. You can use this key pair to log in to your instances with SSH.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
instanceRole (string) --
The Amazon ECS instance profile applied to Amazon EC2 instances in a compute environment. You can specify the short name or full Amazon Resource Name (ARN) of an instance profile. For example, `` ecsInstanceRole `` or ``arn:aws:iam::<aws_account_id> :instance-profile/ecsInstanceRole `` . For more information, see Amazon ECS instance role in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
tags (dict) --
Key-value pair tags to be applied to EC2 resources that are launched in the compute environment. For Batch, these take the form of "String1": "String2" , where String1 is the tag key and String2 is the tag value-for example, { "Name": "Batch Instance - C4OnDemand" } . This is helpful for recognizing your Batch instances in the Amazon EC2 console. Updating these tags requires an infrastructure update to the compute environment. For more information, see Updating compute environments in the Batch User Guide . These tags aren't seen when using the Batch ListTagsForResource API operation.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
placementGroup (string) --
The Amazon EC2 placement group to associate with your compute resources. If you intend to submit multi-node parallel jobs to your compute environment, you should consider creating a cluster placement group and associate it with your compute resources. This keeps your multi-node parallel job on a logical grouping of instances within a single Availability Zone with high network flow potential. For more information, see Placement groups in the Amazon EC2 User Guide for Linux Instances .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
bidPercentage (integer) --
The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, then the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage. If you leave this field empty, the default value is 100% of the On-Demand price.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
spotIamFleetRole (string) --
The Amazon Resource Name (ARN) of the Amazon EC2 Spot Fleet IAM role applied to a SPOT compute environment. This role is required if the allocation strategy set to BEST_FIT or if the allocation strategy isn't specified. For more information, see Amazon EC2 spot fleet role in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Warning
To tag your Spot Instances on creation, the Spot Fleet IAM role specified here must use the newer AmazonEC2SpotFleetTaggingRole managed policy. The previously recommended AmazonEC2SpotFleetRole managed policy doesn't have the required permissions to tag Spot Instances. For more information, see Spot instances not tagged on creation in the Batch User Guide .
launchTemplate (dict) --
The launch template to use for your compute resources. Any other compute resource parameters that you specify in a CreateComputeEnvironment API operation override the same parameters in the launch template. You must specify either the launch template ID or launch template name in the request, but not both. For more information, see Launch template support in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
launchTemplateId (string) --
The ID of the launch template.
launchTemplateName (string) --
The name of the launch template.
version (string) --
The version number of the launch template, $Latest , or $Default .
If the value is $Latest , the latest version of the launch template is used. If the value is $Default , the default version of the launch template is used.
Warning
If the AMI ID that's used in a compute environment is from the launch template, the AMI isn't changed when the compute environment is updated. It's only changed if the updateToLatestImageVersion parameter for the compute environment is set to true . During an infrastructure update, if either $Latest or $Default is specified, Batch re-evaluates the launch template version, and it might use a different version of the launch template. This is the case even if the launch template isn't specified in the update. When updating a compute environment, changing the launch template requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Default: $Default .
ec2Configuration (list) --
Provides information that's used to select Amazon Machine Images (AMIs) for EC2 instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL2 .
One or two values can be provided.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
(dict) --
Provides information used to select Amazon Machine Images (AMIs) for instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL2 (Amazon Linux 2 ).
Note
This object isn't applicable to jobs that are running on Fargate resources.
imageType (string) --
The image type to match with the instance type to select an AMI. The supported values are different for ECS and EKS resources.
ECS
If the imageIdOverride parameter isn't specified, then a recent Amazon ECS-optimized Amazon Linux 2 AMI (ECS_AL2 ) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon ECS optimized AMI for that image type that's supported by Batch is used.
ECS_AL2
Amazon Linux 2 : Default for all non-GPU instance families.
ECS_AL2_NVIDIA
Amazon Linux 2 (GPU) : Default for all GPU instance families (for example
P4andG4) and can be used for all non Amazon Web Services Graviton-based instance types.ECS_AL1
Amazon Linux . Amazon Linux has reached the end-of-life of standard support. For more information, see Amazon Linux AMI .
EKS
If the imageIdOverride parameter isn't specified, then a recent Amazon EKS-optimized Amazon Linux AMI (EKS_AL2 ) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon EKS optimized AMI for that image type that Batch supports is used.
EKS_AL2
Amazon Linux 2 : Default for all non-GPU instance families.
EKS_AL2_NVIDIA
Amazon Linux 2 (accelerated) : Default for all GPU instance families (for example,
P4andG4) and can be used for all non Amazon Web Services Graviton-based instance types.
imageIdOverride (string) --
The AMI ID used for instances launched in the compute environment that match the image type. This setting overrides the imageId set in the computeResource object.
Note
The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide .

The contents of the host parameter determine whether your data volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.
Note
This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
sourcePath (string) --
The path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location doesn't 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.

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 don't specify a transit encryption port, it uses the port selection strategy that the Amazon EFS mount helper uses. The value must be between 0 and 65,535. 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 enforces the path set on the EFS access point.

maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see ` --memory-swap details <https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details>`__ in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
swappiness (integer) --
You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap , then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run .
Consider the following when you use a per-container swap configuration.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
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 might 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
Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
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 | grep "Server API version"
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 .

If a value isn't specified for maxSwap , then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run .
Consider the following when you use a per-container swap configuration.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
logConfiguration (dict) --

The Amazon Resource Name (ARN) of the job queue.
state (string) --
Describes the ability of the queue to accept new jobs. If the job queue state is ENABLED , it can accept jobs. If the job queue state is DISABLED , new jobs can't be added to the queue, but jobs already in the queue can finish.
schedulingPolicyArn (string) --
The Amazon Resource Name (ARN) of the scheduling policy. The format is aws:*Partition* :batch:*Region* :*Account* :scheduling-policy/*Name* `` . For example, ``aws:aws:batch:us-west-2:123456789012:scheduling-policy/MySchedulingPolicy .

The status of the job queue (for example, CREATING or VALID ).
statusReason (string) --
A short, human-readable string to provide additional details for the current status of the job queue.
priority (integer) --
The priority of the job queue. Job queues with a higher priority (or a higher integer value for the priority parameter) are evaluated first when associated with the same compute environment. Priority is determined in descending order. For example, a job queue with a priority value of 10 is given scheduling preference over a job queue with a priority value of 1 . All of the compute environments must be either EC2 (EC2 or SPOT ) or Fargate (FARGATE or FARGATE_SPOT ). EC2 and Fargate compute environments can't be mixed.
computeEnvironmentOrder (list) --
The compute environments that are attached to the job queue and the order that job placement is preferred. Compute environments are selected for job placement in ascending order.
(dict) --
The order that compute environments are tried in for job placement within a queue. Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first. Compute environments must be in the VALID state before you can associate them with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT ) or Fargate (FARGATE or FARGATE_SPOT ); EC2 and Fargate compute environments can't be mixed.
Note
All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.

The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see ` --memory-swap details <https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details>`__ in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap , then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run .
Consider the following when you use a per-container swap configuration.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
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 might 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, alternatively, it must be configured 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
Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers might 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 | grep "Server API version"
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 .

If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.
Note
This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
The path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location doesn't 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.
Note
This parameter isn't applicable to jobs that run on Fargate resources. Don't provide this for these jobs.
The name of the volume. It can be up to 255 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_). This name is referenced in the sourceVolume parameter of container definition mountPoints .
This parameter is specified when you're using an Amazon Elastic File System file system for job storage. Jobs that are running on Fargate resources must specify a platformVersion of at least 1.4.0 .
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 is used instead. Specifying / has the same effect as omitting this parameter. The maximum length is 4,096 characters.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / , which enforces the path set on the Amazon EFS access point.
Determines whether 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 don't specify a transit encryption port, it uses the port selection strategy that the Amazon EFS mount helper uses. The value must be between 0 and 65,535. 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 enforces 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 Batch job IAM role defined in a job 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 Batch User Guide . EFS IAM authorization requires that TransitEncryption be ENABLED and that a JobRoleArn is specified.

The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see ` --memory-swap details <https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details>`__ in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap , then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run .
Consider the following when you use a per-container swap configuration.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
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 might 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
Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
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 | grep "Server API version"
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 .

Response Structure
The list of scheduling policies.
An object that represents a scheduling policy.
The name of the scheduling policy.
The Amazon Resource Name (ARN) of the scheduling policy. An example is ``arn:aws :batch:us-east-1 :123456789012 :scheduling-policy/HighPriority `` .
The fair share policy for the scheduling policy.
The amount of time (in seconds) to use to calculate a fair share percentage for each fair share identifier in use. A value of zero (0) indicates that only current usage is measured. The decay allows for more recently run jobs to have more weight than jobs that ran earlier. The maximum supported value is 604800 (1 week).
A value used to reserve some of the available maximum vCPU for fair share identifiers that aren't already used.
The reserved ratio is ``(computeReservation /100)^*ActiveFairShares* `` where `` ActiveFairShares `` is the number of active fair share identifiers.
For example, a computeReservation value of 50 indicates that Batchreserves 50% of the maximum available vCPU if there's only one fair share identifier. It reserves 25% if there are two fair share identifiers. It reserves 12.5% if there are three fair share identifiers. A computeReservation value of 25 indicates that Batch should reserve 25% of the maximum available vCPU if there's only one fair share identifier, 6.25% if there are two fair share identifiers, and 1.56% if there are three fair share identifiers.
The minimum value is 0 and the maximum value is 99.
An array of SharedIdentifier objects that contain the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0 .
Specifies the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0 .
A fair share identifier or fair share identifier prefix. If the string ends with an asterisk (*), this entry specifies the weight factor to use for fair share identifiers that start with that prefix. The list of fair share identifiers in a fair share policy can't overlap. For example, you can't have one that specifies a shareIdentifier of UserA* and another that specifies a shareIdentifier of UserA-1 .
There can be no more than 500 fair share identifiers active in a job queue.
The string is limited to 255 alphanumeric characters, and can be followed by an asterisk (*).
The weight factor for the fair share identifier. The default value is 1.0. A lower value has a higher priority for compute resources. For example, jobs that use a share identifier with a weight factor of 0.125 (1/8) get 8 times the compute resources of jobs that use a share identifier with a weight factor of 1.
The smallest supported value is 0.0001, and the largest supported value is 999.9999.
The tags that you apply to the scheduling policy to categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging Amazon Web Services resources in Amazon Web Services General Reference .

filters parameter is specified, the jobStatus parameter is ignored and jobs with any status are returned. If you don't specify a status, only RUNNING jobs are returned.ListJobs in paginated output. When this parameter is used, ListJobs only returns maxResults results in a single page and a nextToken response element. The remaining results of the initial request can be seen by sending another ListJobs request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then ListJobs returns up to 100 results and a nextToken value if applicable.The nextToken value returned from a previous paginated ListJobs request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.
Note
Treat this token as an opaque identifier that's only used to retrieve the next items in a list and not for other programmatic purposes.
The filter to apply to the query. Only one filter can be used at a time. When the filter is used, jobStatus is ignored. The filter doesn't apply to child jobs in an array or multi-node parallel (MNP) jobs. The results are sorted by the createdAt field, with the most recent jobs being first.
JOB_NAME
The value of the filter is a case-insensitive match for the job name. If the value ends with an asterisk (*), the filter matches any job name that begins with the string before the '*'. This corresponds to the jobName value. For example, test1 matches both Test1 and test1 , and test1* matches both test1 and Test10 . When the JOB_NAME filter is used, the results are grouped by the job name and version.
JOB_DEFINITION
The value for the filter is the name or Amazon Resource Name (ARN) of the job definition. This corresponds to the jobDefinition value. The value is case sensitive. When the value for the filter is the job definition name, the results include all the jobs that used any revision of that job definition name. If the value ends with an asterisk (*), the filter matches any job definition name that begins with the string before the '*'. For example, jd1 matches only jd1 , and jd1* matches both jd1 and jd1A . The version of the job definition that's used doesn't affect the sort order. When the JOB_DEFINITION filter is used and the ARN is used (which is in the form arn:${Partition}:batch:${Region}:${Account}:job-definition/${JobDefinitionName}:${Revision} ), the results include jobs that used the specified revision of the job definition. Asterisk (*) isn't supported when the ARN is used.
BEFORE_CREATED_AT
The value for the filter is the time that's before the job was created. This corresponds to the createdAt value. The value is a string representation of the number of milliseconds since 00:00:00 UTC (midnight) on January 1, 1970.
AFTER_CREATED_AT
The value for the filter is the time that's after the job was created. This corresponds to the createdAt value. The value is a string representation of the number of milliseconds since 00:00:00 UTC (midnight) on January 1, 1970.
A filter name and value pair that's used to return a more specific list of results from a ListJobs API operation.
The name of the filter. Filter names are case sensitive.
The filter values.

[REQUIRED]
The name of the job definition to register. It can be up to 128 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).
[REQUIRED]
The type of job definition. For more information about multi-node parallel jobs, see Creating a multi-node parallel job definition in the Batch User Guide .
Note
If the job is run on Fargate resources, then multinode isn't supported.
Default parameter substitution placeholders to set in the job definition. Parameters are specified as a key-value pair mapping. Parameters in a SubmitJob request override any corresponding parameter defaults from the job definition.
The scheduling priority for jobs that are submitted with this job definition. This only affects jobs in job queues with a fair share policy. Jobs with a higher scheduling priority are scheduled before jobs with a lower scheduling priority.
The minimum supported value is 0 and the maximum supported value is 9999.
An object with various properties specific to Amazon ECS based single-node container-based jobs. If the job definition's type parameter is container , then you must specify either containerProperties or nodeProperties . This must not be specified for Amazon EKS based job definitions.
Note
If the job runs on Fargate resources, then you must not specify nodeProperties ; use only containerProperties .
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 `` repository-url /image :tag `` . It can be 255 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), underscores (_), colons (:), periods (.), forward slashes (/), and number signs (#). This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run .
Note
Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
registry/repository[:tag] or registry/repository[@digest] naming conventions. For example, ``public.ecr.aws/registry_alias /my-web-app :latest `` .123456789012.dkr.ecr.<region-name>.amazonaws.com/<repository-name> ).ubuntu or mongo ).amazon/amazon-ecs-agent ).quay.io/assemblyline/ubuntu ).This parameter is deprecated, use resourceRequirements to specify the vCPU requirements for the job definition. It's not supported for jobs running on Fargate resources. For jobs running on EC2 resources, it specifies the number of vCPUs reserved for the job.
Each vCPU is equivalent to 1,024 CPU shares. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run . The number of vCPUs must be specified but can be specified in several places. You must specify it at least once for each node.
This parameter is deprecated, use resourceRequirements to specify the memory requirements for the job definition. It's not supported for jobs running on Fargate resources. For jobs that run on EC2 resources, it specifies the memory hard limit (in MiB) for a container. If your container attempts to exceed the specified number, it's terminated. You must specify at least 4 MiB of memory for a job using this parameter. The memory hard limit can be specified in several places. It must be specified for each node at least once.
The command that's 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 .
The Amazon Resource Name (ARN) of the IAM role that the container can assume for Amazon Web Services permissions. For more information, see IAM roles for tasks in the Amazon Elastic Container Service Developer Guide .
The Amazon Resource Name (ARN) of the execution role that Batch can assume. For jobs that run on Fargate resources, you must provide an execution role. For more information, see Batch execution IAM role in the Batch User Guide .
A list of data volumes used in a job.
A data volume that's used in a job's container properties.
The contents of the host parameter determine whether your data volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.
Note
This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
The path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location doesn't 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.
Note
This parameter isn't applicable to jobs that run on Fargate resources. Don't provide this for these jobs.
The name of the volume. It can be up to 255 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_). This name is referenced in the sourceVolume parameter of container definition mountPoints .

The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see ` --memory-swap details <https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details>`__ in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap , then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run .
Consider the following when you use a per-container swap configuration.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
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 might 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
Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
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 | grep "Server API version"
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 .

However, the data isn't guaranteed to persist after the containers that are associated with it stop running.
Note
This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
The path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location doesn't 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.
Note
This parameter isn't applicable to jobs that run on Fargate resources. Don't provide this for these jobs.

VCPU= 4type="VCPU"
The number of vCPUs 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 . Each vCPU is equivalent to 1,024 CPU shares. For EC2 resources, you must specify at least one vCPU. This is required but can be specified in several places; it must be specified for each node at least once.
For jobs that are running on Fargate resources, then value must match one of the supported values and the MEMORY values must be one of the values supported for that VCPU value. The supported values are 0.25, 0.5, 1, 2, and 4

The type of resource to assign to a container. The supported resources include GPU , MEMORY , and VCPU .
Linux-specific modifications that are applied to the container, such as details for device mappings.
Any of the 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
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
An object that represents a container instance host device.
Note
This object isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
The path for the device on the host container instance.
The path inside the container that's used to expose the host device. By default, the hostPath value is used.
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.
If true, 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 | grep "Server API version"
The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide this parameter for this resource type.
The container path, mount options, and size of the tmpfs mount.
Note
This object isn't applicable to jobs that are running on Fargate resources.
The absolute file path in the container where the tmpfs volume is mounted.
The 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 is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see ` --memory-swap details <https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details>`__ in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap , then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run .
Consider the following when you use a per-container swap configuration.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
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 might 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
Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
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 | grep "Server API version"
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. The valid values that are listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.
The supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , and splunk .
Note
Jobs that are running on Fargate resources are restricted to the awslogs and splunk log drivers.
awslogs
Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs log driver in the Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.
fluentd
Specifies the Fluentd logging driver. For more information including usage and options, see Fluentd logging driver in the Docker documentation .
gelf
Specifies the Graylog Extended Format (GELF) logging driver. For more information including usage and options, see Graylog Extended Format logging driver in the Docker documentation .
journald
Specifies the journald logging driver. For more information including usage and options, see Journald logging driver in the Docker documentation .

syslog
Specifies the syslog logging driver. For more information including usage and options, see Syslog logging driver in the Docker documentation .
Note
If you have a custom driver that's not listed earlier that you want to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.
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 | grep "Server API version"
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.

Array of up to 5 objects that specify the conditions where jobs are retried or failed. If this parameter is specified, then the attempts parameter must also be specified. If none of the listed conditions match, then the job is retried.
Specifies an array of up to 5 conditions to be met, and an action to take (RETRY or EXIT ) if all conditions are met. If none of the EvaluateOnExit conditions in a RetryStrategy match, then the job is retried.
Contains a glob pattern to match against the StatusReason returned for a job. The pattern can contain up to 512 characters. It can contain letters, numbers, periods (.), colons (:), and white spaces (including spaces or tabs). It can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.
Contains a glob pattern to match against the Reason returned for a job. The pattern can contain up to 512 characters. It can contain letters, numbers, periods (.), colons (:), and white space (including spaces and tabs). It can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.
Contains a glob pattern to match against the decimal representation of the ExitCode returned for a job. The pattern can be up to 512 characters long. It can contain only numbers, and can end with an asterisk (*) so that only the start of the string needs to be an exact match.
The string can contain up to 512 characters.
Specifies the action to take if all of the specified conditions (onStatusReason , onReason , and onExitCode ) are met. The values aren't case sensitive.
Specifies whether to propagate the tags from the job or job definition to the corresponding Amazon ECS task. If no value is specified, the tags are not propagated. Tags can only be propagated to the tasks during task creation. For tags with the same name, job tags are given priority over job definitions tags. If the total number of combined tags from the job and job definition is over 50, the job is moved to the FAILED state.
Note
If the job runs on Amazon EKS resources, then you must not specify propagateTags .
The timeout configuration for jobs that are submitted with this job definition, after which Batch terminates your jobs if they have not finished. If a job is terminated due to a timeout, it isn't retried. The minimum value for the timeout is 60 seconds. Any timeout configuration that's specified during a SubmitJob operation overrides the timeout configuration defined here. For more information, see Job Timeouts in the Batch User Guide .
The job timeout time (in seconds) that's measured from the job attempt's startedAt timestamp. After this time passes, Batch terminates your jobs if they aren't finished. The minimum value for the timeout is 60 seconds.
The tags that you apply to the job definition to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging Amazon Web Services Resources in Batch User Guide .
The platform capabilities required by the job definition. If no value is specified, it defaults to EC2 . To run the job on Fargate resources, specify FARGATE .
Note
If the job runs on Amazon EKS resources, then you must not specify platformCapabilities .
An object with various properties that are specific to Amazon EKS based jobs. This must not be specified for Amazon ECS based job definitions.

Indicates if the pod uses the hosts' network IP address. The default value is true . Setting this to false enables the Kubernetes pod networking model. Most Batch workloads are egress-only and don't require the overhead of IP allocation for each pod for incoming connections. For more information, see Host namespaces and Pod networking in the Kubernetes documentation .
The DNS policy for the pod. The default value is ClusterFirst . If the hostNetwork parameter is not specified, the default is ClusterFirstWithHostNet . ClusterFirst indicates that any DNS query that does not match the configured cluster domain suffix is forwarded to the upstream nameserver inherited from the node. For more information, see Pod's DNS policy in the Kubernetes documentation .

The properties of the container that's used on the Amazon EKS pod.
EKS container properties are used in job definitions for Amazon EKS based job definitions to describe the properties for a container node in the pod that's launched as part of a job. This can't be specified for Amazon ECS based job definitions.
The name of the container. If the name isn't specified, the default name "Default " is used. Each container in a pod must have a unique name.
The Docker image used to start the container.
The image pull policy for the container. Supported values are Always , IfNotPresent , and Never . This parameter defaults to IfNotPresent . However, if the :latest tag is specified, it defaults to Always . For more information, see Updating images in the Kubernetes documentation .
The entrypoint for the container. This isn't run within a shell. If this isn't specified, the ENTRYPOINT of the container image is used. Environment variable references are expanded using the container's environment.
If the referenced environment variable doesn't exist, the reference in the command isn't changed. For example, if the reference is to "$(NAME1) " and the NAME1 environment variable doesn't exist, the command string will remain "$(NAME1) ." $$ is replaced with $ and the resulting string isn't expanded. For example, $$(VAR_NAME) will be passed as $(VAR_NAME) whether or not the VAR_NAME environment variable exists. The entrypoint can't be updated. For more information, see ENTRYPOINT in the Dockerfile reference and Define a command and arguments for a container and Entrypoint in the Kubernetes documentation .
An array of arguments to the entrypoint. If this isn't specified, the CMD of the container image is used. This corresponds to the args member in the Entrypoint portion of the Pod in Kubernetes. Environment variable references are expanded using the container's environment.
If the referenced environment variable doesn't exist, the reference in the command isn't changed. For example, if the reference is to "$(NAME1) " and the NAME1 environment variable doesn't exist, the command string will remain "$(NAME1) ." $$ is replaced with $ , and the resulting string isn't expanded. For example, $$(VAR_NAME) is passed as $(VAR_NAME) whether or not the VAR_NAME environment variable exists.

submit_job(**kwargs)¶Submits an Batch job from a job definition. Parameters that are specified during SubmitJob override parameters defined in the job definition. vCPU and memory requirements that are specified in the resourceRequirements objects in the job definition are the exception. They can't be overridden this way using the memory and vcpus parameters. Rather, you must specify updates to job definition parameters in a resourceRequirements object that's included in the containerOverrides parameter.
Note
Job queues with a scheduling policy are limited to 500 active fair share identifiers at a time.
Warning
Jobs that run on Fargate resources can't be guaranteed to run for more than 14 days. This is because, after 14 days, Fargate resources might become unavailable and job might be terminated.

[REQUIRED]
The name or full Amazon Resource Name (ARN) of the compute environment to update.
The state of the compute environment. Compute environments in the ENABLED state can accept jobs from a queue and scale in or out automatically based on the workload demand of its associated queues.
If the state is ENABLED , then the Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically, based on the job queue demand.
If the state is DISABLED , then the Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out. However, they scale in to minvCpus value after instances become idle.
Details of the compute resources managed by the compute environment. Required for a managed compute environment. For more information, see Compute Environments in the Batch User Guide .
The minimum number of Amazon EC2 vCPUs that an environment should maintain (even if the compute environment is DISABLED ).
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The maximum number of Amazon EC2 vCPUs that an environment can reach.
Note
With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance. That is, no more than a single instance from among those specified in your compute environment.
The desired number of Amazon EC2 vCPUS in the compute environment. Batch modifies this value between the minimum and maximum values based on job queue demand.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The VPC subnets where the compute resources are launched. Fargate compute resources can contain up to 16 subnets. For Fargate compute resources, providing an empty list will be handled as if this parameter wasn't specified and no change is made. For EC2 compute resources, providing an empty list removes the VPC subnets from the compute resource. For more information, see VPCs and subnets in the Amazon VPC User Guide .
When updating a compute environment, changing the VPC subnets requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
The Amazon EC2 security groups that are associated with instances launched in the compute environment. This parameter is required for Fargate compute resources, where it can contain up to 5 security groups. For Fargate compute resources, providing an empty list is handled as if this parameter wasn't specified and no change is made. For EC2 compute resources, providing an empty list removes the security groups from the compute resource.
When updating a compute environment, changing the EC2 security groups requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
The allocation strategy to use for the compute resource if there's not enough instances of the best fitting instance type that can be allocated. This might be because of availability of the instance type in the Region or Amazon EC2 service limits . For more information, see Allocation strategies in the Batch User Guide .
When updating a compute environment, changing the allocation strategy requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide . BEST_FIT isn't supported when updating a compute environment.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
BEST_FIT_PROGRESSIVE
Batch selects additional instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types with lower cost vCPUs. If additional instances of the previously selected instance types aren't available, Batch selects new instance types.
SPOT_CAPACITY_OPTIMIZED
Batch selects one or more instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.
With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.
The instances types that can be launched. You can specify instance families to launch any instance type within those families (for example, c5 or p3 ), or you can specify specific sizes within a family (such as c5.8xlarge ). You can also choose optimal to select instance types (from the C4, M4, and R4 instance families) that match the demand of your job queues.
When updating a compute environment, changing this setting requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Note
When you create a compute environment, the instance types that you select for the compute environment must share the same architecture. For example, you can't mix x86 and ARM instances in the same compute environment.
Note
Currently, optimal uses instance types from the C4, M4, and R4 instance families. In Regions that don't have instance types from those instance families, instance types from the C5, M5, and R5 instance families are used.
The Amazon EC2 key pair that's used for instances launched in the compute environment. You can use this key pair to log in to your instances with SSH. To remove the Amazon EC2 key pair, set this value to an empty string.
When updating a compute environment, changing the EC2 key pair requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The Amazon ECS instance profile applied to Amazon EC2 instances in a compute environment. You can specify the short name or full Amazon Resource Name (ARN) of an instance profile. For example, `` ecsInstanceRole `` or ``arn:aws:iam::<aws_account_id> :instance-profile/ecsInstanceRole `` . For more information, see Amazon ECS instance role in the Batch User Guide .
When updating a compute environment, changing this setting requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Key-value pair tags to be applied to EC2 resources that are launched in the compute environment. For Batch, these take the form of "String1": "String2" , where String1 is the tag key and String2 is the tag value-for example, { "Name": "Batch Instance - C4OnDemand" } . This is helpful for recognizing your Batch instances in the Amazon EC2 console. These tags aren't seen when using the Batch ListTagsForResource API operation.
When updating a compute environment, changing this setting requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The Amazon EC2 placement group to associate with your compute resources. If you intend to submit multi-node parallel jobs to your compute environment, you should consider creating a cluster placement group and associate it with your compute resources. This keeps your multi-node parallel job on a logical grouping of instances within a single Availability Zone with high network flow potential. For more information, see Placement groups in the Amazon EC2 User Guide for Linux Instances .
When updating a compute environment, changing the placement group requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage.
When updating a compute environment, changing the bid percentage requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The updated launch template to use for your compute resources. You must specify either the launch template ID or launch template name in the request, but not both. For more information, see Launch template support in the Batch User Guide . To remove the custom launch template and use the default launch template, set launchTemplateId or launchTemplateName member of the launch template specification to an empty string. Removing the launch template from a compute environment will not remove the AMI specified in the launch template. In order to update the AMI specified in a launch template, the updateToLatestImageVersion parameter must be set to true .
When updating a compute environment, changing the launch template requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
The ID of the launch template.
The name of the launch template.
The version number of the launch template, $Latest , or $Default .
If the value is $Latest , the latest version of the launch template is used. If the value is $Default , the default version of the launch template is used.
Warning
If the AMI ID that's used in a compute environment is from the launch template, the AMI isn't changed when the compute environment is updated. It's only changed if the updateToLatestImageVersion parameter for the compute environment is set to true . During an infrastructure update, if either $Latest or $Default is specified, Batch re-evaluates the launch template version, and it might use a different version of the launch template. This is the case even if the launch template isn't specified in the update. When updating a compute environment, changing the launch template requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Default: $Default .
Provides information used to select Amazon Machine Images (AMIs) for EC2 instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL2 .
When updating a compute environment, changing this setting requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide . To remove the EC2 configuration and any custom AMI ID specified in imageIdOverride , set this value to an empty string.
One or two values can be provided.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Provides information used to select Amazon Machine Images (AMIs) for instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL2 (Amazon Linux 2 ).
Note
This object isn't applicable to jobs that are running on Fargate resources.
The image type to match with the instance type to select an AMI. The supported values are different for ECS and EKS resources.
ECS
If the imageIdOverride parameter isn't specified, then a recent Amazon ECS-optimized Amazon Linux 2 AMI (ECS_AL2 ) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon ECS optimized AMI for that image type that's supported by Batch is used.
ECS_AL2Amazon Linux 2 : Default for all non-GPU instance families.
ECS_AL2_NVIDIAAmazon Linux 2 (GPU) : Default for all GPU instance families (for example
P4andG4) and can be used for all non Amazon Web Services Graviton-based instance types.ECS_AL1Amazon Linux . Amazon Linux has reached the end-of-life of standard support. For more information, see Amazon Linux AMI .
EKS
If the imageIdOverride parameter isn't specified, then a recent Amazon EKS-optimized Amazon Linux AMI (EKS_AL2 ) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon EKS optimized AMI for that image type that Batch supports is used.
EKS_AL2Amazon Linux 2 : Default for all non-GPU instance families.
EKS_AL2_NVIDIAAmazon Linux 2 (accelerated) : Default for all GPU instance families (for example,
P4andG4) and can be used for all non Amazon Web Services Graviton-based instance types.
The AMI ID used for instances launched in the compute environment that match the image type. This setting overrides the imageId set in the computeResource object.
Note
The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide .
The Kubernetes version for the compute environment. If you don't specify a value, the latest version that Batch supports is used.
Specifies whether the AMI ID is updated to the latest one that's supported by Batch when the compute environment has an infrastructure update. The default value is false .
Note
An AMI ID can either be specified in the imageId or imageIdOverride parameters or be determined by the launch template that's specified in the launchTemplate parameter. If an AMI ID is specified any of these ways, this parameter is ignored. For more information about to update AMI IDs during an infrastructure update, see Updating the AMI ID in the Batch User Guide .
When updating a compute environment, changing this setting requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
The type of compute environment: EC2 , SPOT , FARGATE , or FARGATE_SPOT . For more information, see Compute environments in the Batch User Guide .
If you choose SPOT , you must also specify an Amazon EC2 Spot Fleet role with the spotIamFleetRole parameter. For more information, see Amazon EC2 spot fleet role in the Batch User Guide .
When updating a compute environment, changing the type of a compute environment requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
The Amazon Machine Image (AMI) ID used for instances launched in the compute environment. This parameter is overridden by the imageIdOverride member of the Ec2Configuration structure. To remove the custom AMI ID and use the default AMI ID, set this value to an empty string.
When updating a compute environment, changing the AMI ID requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Note
The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide .
The full Amazon Resource Name (ARN) of the IAM role that allows Batch to make calls to other Amazon Web Services services on your behalf. For more information, see Batch service IAM role in the Batch User Guide .
Warning
If the compute environment has a service-linked role, it can't be changed to use a regular IAM role. Likewise, if the compute environment has a regular IAM role, it can't be changed to use a service-linked role. To update the parameters for the compute environment that require an infrastructure update to change, the AWSServiceRoleForBatch service-linked role must be used. For more information, see Updating compute environments in the Batch User Guide .
If your specified role has a path other than / , then you must either specify the full role ARN (recommended) or prefix the role name with the path.
Note
Depending on how you created your Batch service role, its ARN might contain the service-role path prefix. When you only specify the name of the service role, Batch assumes that your ARN doesn't use the service-role path prefix. Because of this, we recommend that you specify the full ARN of your service role when you create compute environments.
Specifies the updated infrastructure update policy for the compute environment. For more information about infrastructure updates, see Updating compute environments in the Batch User Guide .
Specifies whether jobs are automatically terminated when the computer environment infrastructure is updated. The default value is false .
Specifies the job timeout (in minutes) when the compute environment infrastructure is updated. The default value is 30.

Priority is determined in descending order. For example, a job queue with a priority value of 10 is given scheduling preference over a job queue with a priority value of 1 . All of the compute environments must be either EC2 (EC2 or SPOT ) or Fargate (FARGATE or FARGATE_SPOT ). EC2 and Fargate compute environments can't be mixed.Details the set of compute environments mapped to a job queue and their order relative to each other. This is one of the parameters used by the job scheduler to determine which compute environment runs a given job. Compute environments must be in the VALID state before you can associate them with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT ) or Fargate (FARGATE or FARGATE_SPOT ). EC2 and Fargate compute environments can't be mixed.
Note
All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.
The order that compute environments are tried in for job placement within a queue. Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first. Compute environments must be in the VALID state before you can associate them with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT ) or Fargate (FARGATE or FARGATE_SPOT ); EC2 and Fargate compute environments can't be mixed.

'shareDecaySeconds': 123,
'computeReservation': 123,
'shareDistribution': [
{
'shareIdentifier': 'string',
'weightFactor': ...
},
]
}
)
[REQUIRED]
The Amazon Resource Name (ARN) of the scheduling policy to update.
The fair share policy.
The amount of time (in seconds) to use to calculate a fair share percentage for each fair share identifier in use. A value of zero (0) indicates that only current usage is measured. The decay allows for more recently run jobs to have more weight than jobs that ran earlier. The maximum supported value is 604800 (1 week).
A value used to reserve some of the available maximum vCPU for fair share identifiers that aren't already used.
The reserved ratio is ``(computeReservation /100)^*ActiveFairShares* `` where `` ActiveFairShares `` is the number of active fair share identifiers.
For example, a computeReservation value of 50 indicates that Batchreserves 50% of the maximum available vCPU if there's only one fair share identifier. It reserves 25% if there are two fair share identifiers. It reserves 12.5% if there are three fair share identifiers. A computeReservation value of 25 indicates that Batch should reserve 25% of the maximum available vCPU if there's only one fair share identifier, 6.25% if there are two fair share identifiers, and 1.56% if there are three fair share identifiers.
The minimum value is 0 and the maximum value is 99.
An array of SharedIdentifier objects that contain the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0 .
Specifies the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0 .
A fair share identifier or fair share identifier prefix. If the string ends with an asterisk (*), this entry specifies the weight factor to use for fair share identifiers that start with that prefix. The list of fair share identifiers in a fair share policy can't overlap. For example, you can't have one that specifies a shareIdentifier of UserA* and another that specifies a shareIdentifier of UserA-1 .
There can be no more than 500 fair share identifiers active in a job queue.
The string is limited to 255 alphanumeric characters, and can be followed by an asterisk (*).
The weight factor for the fair share identifier. The default value is 1.0. A lower value has a higher priority for compute resources. For example, jobs that use a share identifier with a weight factor of 0.125 (1/8) get 8 times the compute resources of jobs that use a share identifier with a weight factor of 1.
The smallest supported value is 0.0001, and the largest supported value is 999.9999.

(dict) --
computeEnvironments (list) --
The list of compute environments.
(dict) --
An object that represents an Batch compute environment.
computeEnvironmentName (string) --
The name of the compute environment. It can be up to 128 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).
computeEnvironmentArn (string) --
The Amazon Resource Name (ARN) of the compute environment.
unmanagedvCpus (integer) --
The maximum number of VCPUs expected to be used for an unmanaged compute environment.
ecsClusterArn (string) --
The Amazon Resource Name (ARN) of the underlying Amazon ECS cluster that the compute environment uses.
tags (dict) --
The tags applied to the compute environment.
type (string) --
The type of the compute environment: MANAGED or UNMANAGED . For more information, see Compute environments in the Batch User Guide .
state (string) --
The state of the compute environment. The valid values are ENABLED or DISABLED .
If the state is ENABLED , then the Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically based on the job queue demand.
If the state is DISABLED , then the Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out. However, they scale in to minvCpus value after instances become idle.
status (string) --
The current status of the compute environment (for example, CREATING or VALID ).
statusReason (string) --
A short, human-readable string to provide additional details for the current status of the compute environment.
computeResources (dict) --
The compute resources defined for the compute environment. For more information, see Compute environments in the Batch User Guide .
type (string) --
The type of compute environment: EC2 , SPOT , FARGATE , or FARGATE_SPOT . For more information, see Compute environments in the Batch User Guide .
If you choose SPOT , you must also specify an Amazon EC2 Spot Fleet role with the spotIamFleetRole parameter. For more information, see Amazon EC2 spot fleet role in the Batch User Guide .
allocationStrategy (string) --
The allocation strategy to use for the compute resource if not enough instances of the best fitting instance type can be allocated. This might be because of availability of the instance type in the Region or Amazon EC2 service limits . For more information, see Allocation strategies in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
BEST_FIT (default)
Batch selects an instance type that best fits the needs of the jobs with a preference for the lowest-cost instance type. If additional instances of the selected instance type aren't available, Batch waits for the additional instances to be available. If there aren't enough instances available or the user is reaching Amazon EC2 service limits , additional jobs aren't run until the currently running jobs are completed. This allocation strategy keeps costs lower but can limit scaling. If you're using Spot Fleets with BEST_FIT , the Spot Fleet IAM Role must be specified. Compute resources that use a BEST_FIT allocation strategy don't support infrastructure updates and can't update some parameters. For more information, see Updating compute environments in the Batch User Guide .
BEST_FIT_PROGRESSIVE
Batch selects additional instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types with lower cost vCPUs. If additional instances of the previously selected instance types aren't available, Batch selects new instance types.
SPOT_CAPACITY_OPTIMIZED
Batch selects one or more instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.
With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.
minvCpus (integer) --
The minimum number of Amazon EC2 vCPUs that an environment should maintain (even if the compute environment is DISABLED ).
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
maxvCpus (integer) --
The maximum number of Amazon EC2 vCPUs that a compute environment can reach.
Note
With both BEST_FIT_PROGRESSIVE and SPOT_CAPACITY_OPTIMIZED allocation strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance. For example, no more than a single instance from among those specified in your compute environment is allocated.
desiredvCpus (integer) --
The desired number of Amazon EC2 vCPUS in the compute environment. Batch modifies this value between the minimum and maximum values based on job queue demand.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
instanceTypes (list) --
The instances types that can be launched. You can specify instance families to launch any instance type within those families (for example, c5 or p3 ), or you can specify specific sizes within a family (such as c5.8xlarge ). You can also choose optimal to select instance types (from the C4, M4, and R4 instance families) that match the demand of your job queues.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Note
When you create a compute environment, the instance types that you select for the compute environment must share the same architecture. For example, you can't mix x86 and ARM instances in the same compute environment.
Note
Currently, optimal uses instance types from the C4, M4, and R4 instance families. In Regions that don't have instance types from those instance families, instance types from the C5, M5, and R5 instance families are used.
imageId (string) --
The Amazon Machine Image (AMI) ID used for instances launched in the compute environment. This parameter is overridden by the imageIdOverride member of the Ec2Configuration structure.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Note
The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide .
subnets (list) --
The VPC subnets where the compute resources are launched. These subnets must be within the same VPC. Fargate compute resources can contain up to 16 subnets. For more information, see VPCs and subnets in the Amazon VPC User Guide .
securityGroupIds (list) --
The Amazon EC2 security groups that are associated with instances launched in the compute environment. One or more security groups must be specified, either in securityGroupIds or using a launch template referenced in launchTemplate . This parameter is required for jobs that are running on Fargate resources and must contain at least one security group. Fargate doesn't support launch templates. If security groups are specified using both securityGroupIds and launchTemplate , the values in securityGroupIds are used.
ec2KeyPair (string) --
The Amazon EC2 key pair that's used for instances launched in the compute environment. You can use this key pair to log in to your instances with SSH.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
instanceRole (string) --
The Amazon ECS instance profile applied to Amazon EC2 instances in a compute environment. You can specify the short name or full Amazon Resource Name (ARN) of an instance profile. For example, `` ecsInstanceRole `` or ``arn:aws:iam::<aws_account_id> :instance-profile/ecsInstanceRole `` . For more information, see Amazon ECS instance role in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
tags (dict) --
Key-value pair tags to be applied to EC2 resources that are launched in the compute environment. For Batch, these take the form of "String1": "String2" , where String1 is the tag key and String2 is the tag value-for example, { "Name": "Batch Instance - C4OnDemand" } . This is helpful for recognizing your Batch instances in the Amazon EC2 console. Updating these tags requires an infrastructure update to the compute environment. For more information, see Updating compute environments in the Batch User Guide . These tags aren't seen when using the Batch ListTagsForResource API operation.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
placementGroup (string) --
The Amazon EC2 placement group to associate with your compute resources. If you intend to submit multi-node parallel jobs to your compute environment, you should consider creating a cluster placement group and associate it with your compute resources. This keeps your multi-node parallel job on a logical grouping of instances within a single Availability Zone with high network flow potential. For more information, see Placement groups in the Amazon EC2 User Guide for Linux Instances .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
bidPercentage (integer) --
The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, then the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage. If you leave this field empty, the default value is 100% of the On-Demand price.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
spotIamFleetRole (string) --
The Amazon Resource Name (ARN) of the Amazon EC2 Spot Fleet IAM role applied to a SPOT compute environment. This role is required if the allocation strategy set to BEST_FIT or if the allocation strategy isn't specified. For more information, see Amazon EC2 spot fleet role in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
Warning
To tag your Spot Instances on creation, the Spot Fleet IAM role specified here must use the newer AmazonEC2SpotFleetTaggingRole managed policy. The previously recommended AmazonEC2SpotFleetRole managed policy doesn't have the required permissions to tag Spot Instances. For more information, see Spot instances not tagged on creation in the Batch User Guide .
launchTemplate (dict) --
The launch template to use for your compute resources. Any other compute resource parameters that you specify in a CreateComputeEnvironment API operation override the same parameters in the launch template. You must specify either the launch template ID or launch template name in the request, but not both. For more information, see Launch template support in the Batch User Guide .
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.
launchTemplateId (string) --
The ID of the launch template.
launchTemplateName (string) --
The name of the launch template.
version (string) --
The version number of the launch template, $Latest , or $Default .
If the value is $Latest , the latest version of the launch template is used. If the value is $Default , the default version of the launch template is used.
Warning
If the AMI ID that's used in a compute environment is from the launch template, the AMI isn't changed when the compute environment is updated. It's only changed if the updateToLatestImageVersion parameter for the compute environment is set to true . During an infrastructure update, if either $Latest or $Default is specified, Batch re-evaluates the launch template version, and it might use a different version of the launch template. This is the case even if the launch template isn't specified in the update. When updating a compute environment, changing the launch template requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide .
Default: $Default .
ec2Configuration (list) --
Provides information that's used to select Amazon Machine Images (AMIs) for EC2 instances in the compute environment. If Ec2Configuration isn't specified, the default is ECS_AL2 .
One or two values can be provided.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

imageType (string) --
The image type to match with the instance type to select an AMI. The supported values are different for ECS and EKS resources.
ECS
If the imageIdOverride parameter isn't specified, then a recent Amazon ECS-optimized Amazon Linux 2 AMI (ECS_AL2 ) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon ECS optimized AMI for that image type that's supported by Batch is used.
ECS_AL2
Amazon Linux 2 : Default for all non-GPU instance families.

EKS
If the imageIdOverride parameter isn't specified, then a recent Amazon EKS-optimized Amazon Linux AMI (EKS_AL2 ) is used. If a new image type is specified in an update, but neither an imageId nor a imageIdOverride parameter is specified, then the latest Amazon EKS optimized AMI for that image type that Batch supports is used.
EKS_AL2
Amazon Linux 2 : Default for all non-GPU instance families.
EKS_AL2_NVIDIA

Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
registry/repository[:tag] or registry/repository[@digest] naming conventions. For example, ``public.ecr.aws/registry_alias /my-web-app :latest `` .123456789012.dkr.ecr.<region-name>.amazonaws.com/<repository-name> ).ubuntu or mongo ).amazon/amazon-ecs-agent ).quay.io/assemblyline/ubuntu ).vcpus (integer) --
This parameter is deprecated, use resourceRequirements to specify the vCPU requirements for the job definition. It's not supported for jobs running on Fargate resources. For jobs running on EC2 resources, it specifies the number of vCPUs reserved for the job.
Each vCPU is equivalent to 1,024 CPU shares. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run . The number of vCPUs must be specified but can be specified in several places. You must specify it at least once for each node.
memory (integer) --
This parameter is deprecated, use resourceRequirements to specify the memory requirements for the job definition. It's not supported for jobs running on Fargate resources. For jobs that run on EC2 resources, it specifies the memory hard limit (in MiB) for a container. If your container attempts to exceed the specified number, it's terminated. You must specify at least 4 MiB of memory for a job using this parameter. The memory hard limit can be specified in several places. It must be specified for each node at least once.
command (list) --

jobRoleArn (string) --
The Amazon Resource Name (ARN) of the IAM role that the container can assume for Amazon Web Services permissions. For more information, see IAM roles for tasks in the Amazon Elastic Container Service Developer Guide .
executionRoleArn (string) --
The Amazon Resource Name (ARN) of the execution role that Batch can assume. For jobs that run on Fargate resources, you must provide an execution role. For more information, see Batch execution IAM role in the Batch User Guide .
volumes (list) --
A list of data volumes used in a job.
(dict) --
A data volume that's used in a job's container properties.
host (dict) --
The contents of the host parameter determine whether your data volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.
Note
This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
sourcePath (string) --
The path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location doesn't 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.
Note
This parameter isn't applicable to jobs that run on Fargate resources. Don't provide this for these jobs.
name (string) --
The name of the volume. It can be up to 255 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_). This name is referenced in the sourceVolume parameter of container definition mountPoints .
efsVolumeConfiguration (dict) --
This parameter is specified when you're using an Amazon Elastic File System file system for job storage. Jobs that are running on Fargate resources must specify a platformVersion of at least 1.4.0 .
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 is used instead. Specifying / has the same effect as omitting this parameter. The maximum length is 4,096 characters.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / , which enforces the path set on the Amazon EFS access point.
transitEncryption (string) --
Determines whether 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 don't specify a transit encryption port, it uses the port selection strategy that the Amazon EFS mount helper uses. The value must be between 0 and 65,535. 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 enforces 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 Batch job IAM role defined in a job definition when mounting the Amazon EFS file system. If enabled, transit encryption must be enabled in the EFSVolumeConfiguration .

EFS IAM authorization requires that TransitEncryption be ENABLED and that a JobRoleArn is specified.
environment (list) --
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 don't recommend using plaintext environment variables for sensitive information, such as credential data.
Note
Environment variables cannot start with "AWS_BATCH ". This naming convention is reserved for variables that Batch sets.

For more information, see ` --memory-swap details <https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details>`__ in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
swappiness (integer) --
You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap , then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run .
Consider the following when you use a per-container swap configuration.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
logConfiguration (dict) --

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 might 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
Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
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 | grep "Server API version"
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 .

devices (list) --
Any of the 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
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
(dict) --
An object that represents a container instance host device.
Note
This object isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
hostPath (string) --
The path for the device on the host container instance.
containerPath (string) --
The path inside the container that's used to expose the host device. By default, the hostPath value is used.
permissions (list) --
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.
initProcessEnabled (boolean) --
If true, 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 | grep "Server API version"

maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see ` --memory-swap details <https://docs.docker.com/config/containers/resource_constraints/#--memory-swap-details>`__ in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance that it's running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
swappiness (integer) --
You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap , then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run .
Consider the following when you use a per-container swap configuration.
Note
By default, the Amazon ECS optimized AMIs don't have swap enabled. You must enable swap on the instance to use this feature. For more information, see Instance store swap volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
maxSwap and swappiness parameters are omitted from a job definition, each container has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.Note
This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.
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 might 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
Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
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 | grep "Server API version"
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 job queue name.
jobQueueArn (string) --
The Amazon Resource Name (ARN) of the job queue.
state (string) --
Describes the ability of the queue to accept new jobs. If the job queue state is ENABLED , it can accept jobs. If the job queue state is DISABLED , new jobs can't be added to the queue, but jobs already in the queue can finish.
schedulingPolicyArn (string) --
The Amazon Resource Name (ARN) of the scheduling policy. The format is aws:*Partition* :batch:*Region* :*Account* :scheduling-policy/*Name* `` . For example, ``aws:aws:batch:us-west-2:123456789012:scheduling-policy/MySchedulingPolicy .
status (string) --
The status of the job queue (for example, CREATING or VALID ).
statusReason (string) --
A short, human-readable string to provide additional details for the current status of the job queue.
priority (integer) --
The priority of the job queue. Job queues with a higher priority (or a higher integer value for the priority parameter) are evaluated first when associated with the same compute environment. Priority is determined in descending order. For example, a job queue with a priority value of 10 is given scheduling preference over a job queue with a priority value of 1 . All of the compute environments must be either EC2 (EC2 or SPOT ) or Fargate (FARGATE or FARGATE_SPOT ). EC2 and Fargate compute environments can't be mixed.
computeEnvironmentOrder (list) --
The compute environments that are attached to the job queue and the order that job placement is preferred. Compute environments are selected for job placement in ascending order.
(dict) --
The order that compute environments are tried in for job placement within a queue. Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first. Compute environments must be in the VALID state before you can associate them with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT ) or Fargate (FARGATE or FARGATE_SPOT ); EC2 and Fargate compute environments can't be mixed.
Note
All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.

filters parameter is specified, the jobStatus parameter is ignored and jobs with any status are returned. If you don't specify a status, only RUNNING jobs are returned.The filter to apply to the query. Only one filter can be used at a time. When the filter is used, jobStatus is ignored. The filter doesn't apply to child jobs in an array or multi-node parallel (MNP) jobs. The results are sorted by the createdAt field, with the most recent jobs being first.
JOB_NAME
The value of the filter is a case-insensitive match for the job name. If the value ends with an asterisk (*), the filter matches any job name that begins with the string before the '*'. This corresponds to the jobName value. For example, test1 matches both Test1 and test1 , and test1* matches both test1 and Test10 . When the JOB_NAME filter is used, the results are grouped by the job name and version.
JOB_DEFINITION
The value for the filter is the name or Amazon Resource Name (ARN) of the job definition. This corresponds to the jobDefinition value. The value is case sensitive. When the value for the filter is the job definition name, the results include all the jobs that used any revision of that job definition name. If the value ends with an asterisk (*), the filter matches any job definition name that begins with the string before the '*'. For example, jd1 matches only jd1 , and jd1* matches both jd1 and jd1A . The version of the job definition that's used doesn't affect the sort order. When the JOB_DEFINITION filter is used and the ARN is used (which is in the form arn:${Partition}:batch:${Region}:${Account}:job-definition/${JobDefinitionName}:${Revision} ), the results include jobs that used the specified revision of the job definition. Asterisk (*) isn't supported when the ARN is used.

(dict) --
jobSummaryList (list) --
A list of job summaries that match the request.
(dict) --
An object that represents summary details of a job.
jobArn (string) --
The Amazon Resource Name (ARN) of the job.
jobId (string) --
The job ID.
jobName (string) --
The job name.
createdAt (integer) --
The Unix timestamp (in milliseconds) for when the job was created. For non-array jobs and parent array jobs, this is when the job entered the SUBMITTED state (at the time SubmitJob was called). For array child jobs, this is when the child job was spawned by its parent and entered the PENDING state.
status (string) --
The current status for the job.
statusReason (string) --
A short, human-readable string to provide more details for the current status of the job.
startedAt (integer) --
The Unix timestamp for when the job was started. More specifically, it's when the job transitioned from the STARTING state to the RUNNING state.
stoppedAt (integer) --
The Unix timestamp for when the job was stopped. More specifically, it's when the job transitioned from the RUNNING state to a terminal state, such as SUCCEEDED or FAILED .
container (dict) --
An object that represents the details of the container that's associated with the job.
exitCode (integer) --
The exit code to return upon completion.
reason (string) --
A short (255 max characters) human-readable string to provide additional details for a running or stopped container.
arrayProperties (dict) --
The array properties of the job, if it's an array job.
size (integer) --
The size of the array job. This parameter is returned for parent array jobs.
index (integer) --
The job index within the array that's associated with this job. This parameter is returned for children of array jobs.
nodeProperties (dict) --
The node properties for a single node in a job summary list.
Note
This isn't applicable to jobs that are running on Fargate resources.
isMainNode (boolean) --
Specifies whether the current node is the main node for a multi-node parallel job.
numNodes (integer) --
The number of nodes that are associated with a multi-node parallel job.
nodeIndex (integer) --
The node index for the node. Node index numbering begins at zero. This index is also available on the node with the AWS_BATCH_JOB_NODE_INDEX environment variable.
jobDefinition (string) --
The Amazon Resource Name (ARN) of the job definition.
NextToken (string) --
A token to resume pagination.
