A low-level client representing AWS CloudFormation:
import boto3
client = boto3.client('cloudformation')
These are the available methods:
Check if an operation can be paginated.
Cancels an update on the specified stack. If the call completes successfully, the stack rolls back the update and reverts to the previous stack configuration.
Note
You can cancel only stacks that are in the UPDATE_IN_PROGRESS state.

Request Syntax
response = client.cancel_update_stack(
StackName='string',
ClientRequestToken='string'
)
[REQUIRED]
The name or the unique stack ID that is associated with the stack.
None
Examples
This example cancels an update of the specified stack.
response = client.cancel_update_stack(
StackName='MyStack',
)
print(response)
Expected Output:

}
For a specified stack that is in the UPDATE_ROLLBACK_FAILED state, continues rolling it back to the UPDATE_ROLLBACK_COMPLETE state. Depending on the cause of the failure, you can manually fix the error and continue the rollback. By continuing the rollback, you can return your stack to a working state (the UPDATE_ROLLBACK_COMPLETE state), and then try to update the stack again.
A stack goes into the UPDATE_ROLLBACK_FAILED state when AWS CloudFormation cannot roll back all changes after a failed stack update. For example, you might have a stack that is rolling back to an old database instance that was deleted outside of AWS CloudFormation. Because AWS CloudFormation doesn't know the database was deleted, it assumes that the database instance still exists and attempts to roll back to it, causing the update rollback to fail.

Request Syntax
response = client.continue_update_rollback(
StackName='string',
RoleARN='string',
ResourcesToSkip=[
'string',
],
ClientRequestToken='string'
)
[REQUIRED]
The name or the unique ID of the stack that you want to continue rolling back.
Note
Don't specify the name of a nested stack (a stack that was created by using the AWS::CloudFormation::Stack resource). Instead, use this operation on the parent stack (the stack that contains the AWS::CloudFormation::Stack resource).
The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to roll back the stack. AWS CloudFormation uses the role's credentials to make calls on your behalf. AWS CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least privilege.
If you don't specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.
A list of the logical IDs of the resources that AWS CloudFormation skips during the continue update rollback operation. You can specify only resources that are in the UPDATE_FAILED state because a rollback failed. You can't specify resources that are in the UPDATE_FAILED state for other reasons, for example, because an update was cancelled. To check why a resource update failed, use the DescribeStackResources action, and view the resource status reason.
Warning
Specify this property to skip rolling back resources that AWS CloudFormation can't successfully roll back. We recommend that you troubleshoot resources before skipping them. AWS CloudFormation sets the status of the specified resources to UPDATE_COMPLETE and continues to roll back the stack. After the rollback is complete, the state of the skipped resources will be inconsistent with the state of the resources in the stack template. Before performing another stack update, you must update the stack or resources to be consistent with each other. If you don't, subsequent stack updates might fail, and the stack will become unrecoverable.
Specify the minimum number of resources required to successfully roll back your stack. For example, a failed resource update might cause dependent resources to fail. In this case, it might not be necessary to skip the dependent resources.
To skip resources that are part of nested stacks, use the following format: NestedStackName.ResourceLogicalID . If you want to specify the logical ID of a stack resource (Type: AWS::CloudFormation::Stack ) in the ResourcesToSkip list, then its corresponding embedded stack must be in one of the following states: DELETE_IN_PROGRESS , DELETE_COMPLETE , or DELETE_FAILED .
Note
Don't confuse a child stack's name with its corresponding logical ID defined in the parent stack. For an example of a continue update rollback operation with nested stacks, see Using ResourcesToSkip to recover a nested stacks hierarchy .

Response Structure
(dict) --
The output for a ContinueUpdateRollback action.
Creates a list of changes that will be applied to a stack so that you can review the changes before executing them. You can create a change set for a stack that doesn't exist or an existing stack. If you create a change set for a stack that doesn't exist, the change set shows all of the resources that AWS CloudFormation will create. If you create a change set for an existing stack, AWS CloudFormation compares the stack's information with the information that you submit in the change set and lists the differences. Use change sets to understand which resources AWS CloudFormation will create or change, and how it will change resources in an existing stack, before you create or update a stack.
To create a change set for a stack that doesn't exist, for the ChangeSetType parameter, specify CREATE . To create a change set for an existing stack, specify UPDATE for the ChangeSetType parameter. After the CreateChangeSet call successfully completes, AWS CloudFormation starts creating the change set. To check the status of the change set or to review it, use the DescribeChangeSet action.
When you are satisfied with the changes the change set will make, execute the change set by using the ExecuteChangeSet action. AWS CloudFormation doesn't make changes until you execute the change set.

[REQUIRED]
The name or the unique ID of the stack for which you are creating a change set. AWS CloudFormation generates the change set by comparing this stack's information with the information that you submit, such as a modified template or different parameter input values.
A structure that contains the body of the revised template, with a minimum length of 1 byte and a maximum length of 51,200 bytes. AWS CloudFormation generates the change set by comparing this template with the template of the stack that you specified.
Conditional: You must specify only TemplateBody or TemplateURL .
The location of the file that contains the revised template. The URL must point to a template (max size: 460,800 bytes) that is located in an S3 bucket. AWS CloudFormation generates the change set by comparing this template with the stack that you specified.
Conditional: You must specify only TemplateBody or TemplateURL .
A list of Parameter structures that specify input parameters for the change set. For more information, see the Parameter data type.
The Parameter data type.
The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.
The input value associated with the parameter.
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
A list of values that you must specify before AWS CloudFormation can update certain stacks. Some stack templates might include resources that can affect permissions in your AWS account, for example, by creating new AWS Identity and Access Management (IAM) users. For those stacks, you must explicitly acknowledge their capabilities by specifying this parameter.
The only valid values are CAPABILITY_IAM and CAPABILITY_NAMED_IAM . The following resources require you to specify this parameter: AWS::IAM::AccessKey , AWS::IAM::Group , AWS::IAM::InstanceProfile , AWS::IAM::Policy , AWS::IAM::Role , AWS::IAM::User , and AWS::IAM::UserToGroupAddition . If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.
If you have IAM resources, you can specify either capability. If you have IAM resources with custom names, you must specify CAPABILITY_NAMED_IAM . If you don't specify this parameter, this action returns an InsufficientCapabilities error.
For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates .
The template resource types that you have permissions to work with if you execute this change set, such as AWS::EC2::Instance , AWS::EC2::* , or Custom::MyCustomInstance .
If the list of resource types doesn't include a resource type that you're updating, the stack update fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for condition keys in IAM policies for AWS CloudFormation. For more information, see Controlling Access with AWS Identity and Access Management in the AWS CloudFormation User Guide.
The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes when executing the change set. AWS CloudFormation uses the role's credentials to make calls on your behalf. AWS CloudFormation uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least privilege.
If you don't specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.
The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.
The triggers to monitor during stack creation or update actions.
By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:
If a specified trigger is missing, the entire stack operation fails and is rolled back.
A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.
The Amazon Resource Name (ARN) of the rollback trigger.
If a specified trigger is missing, the entire stack operation fails and is rolled back.
The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.
The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.
The default is 0 minutes.
If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack , for example) as necessary.
If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.
The Amazon Resource Names (ARNs) of Amazon Simple Notification Service (Amazon SNS) topics that AWS CloudFormation associates with the stack. To remove all associated notification topics, specify an empty list.
Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to resources in the stack. You can specify a maximum of 50 tags.
The Tag type enables you to specify a key-value pair that can be used to store information about an AWS CloudFormation stack.
Required . A string used to identify this tag. You can specify a maximum of 128 characters for a tag key. Tags owned by Amazon Web Services (AWS) have the reserved prefix: aws: .
Required . A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.
[REQUIRED]
The name of the change set. The name must be unique among all change sets that are associated with the specified stack.
A change set name can contain only alphanumeric, case sensitive characters and hyphens. It must start with an alphabetic character and cannot exceed 128 characters.
The type of change set operation. To create a change set for a new stack, specify CREATE . To create a change set for an existing stack, specify UPDATE .
If you create a change set for a new stack, AWS Cloudformation creates a stack with a unique stack ID, but no template or resources. The stack will be in the ` REVIEW_IN_PROGRESS http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-describing-stacks.html#d0e11995`__ state until you execute the change set.
By default, AWS CloudFormation specifies UPDATE . You can't use the UPDATE type to create a change set for a new stack or the CREATE type to create a change set for an existing stack.

The Parameter data type.
The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.
The input value associated with the parameter.
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
Set to true to disable rollback of the stack if stack creation failed. You can specify either DisableRollback or OnFailure , but not both.
Default: false
The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.
The triggers to monitor during stack creation or update actions.
By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:
If a specified trigger is missing, the entire stack operation fails and is rolled back.
A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.
The Amazon Resource Name (ARN) of the rollback trigger.
If a specified trigger is missing, the entire stack operation fails and is rolled back.
The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.
The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.
The default is 0 minutes.
If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack , for example) as necessary.
If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.
The Simple Notification Service (SNS) topic ARNs to publish stack related events. You can find your SNS topic ARNs using the SNS console or your Command Line Interface (CLI).
A list of values that you must specify before AWS CloudFormation can create certain stacks. Some stack templates might include resources that can affect permissions in your AWS account, for example, by creating new AWS Identity and Access Management (IAM) users. For those stacks, you must explicitly acknowledge their capabilities by specifying this parameter.
The only valid values are CAPABILITY_IAM and CAPABILITY_NAMED_IAM . The following resources require you to specify this parameter: AWS::IAM::AccessKey , AWS::IAM::Group , AWS::IAM::InstanceProfile , AWS::IAM::Policy , AWS::IAM::Role , AWS::IAM::User , and AWS::IAM::UserToGroupAddition . If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.
If you have IAM resources, you can specify either capability. If you have IAM resources with custom names, you must specify CAPABILITY_NAMED_IAM . If you don't specify this parameter, this action returns an InsufficientCapabilities error.
For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates .
The template resource types that you have permissions to work with for this create stack action, such as AWS::EC2::Instance , AWS::EC2::* , or Custom::MyCustomInstance . Use the following syntax to describe template resource types: AWS::* (for all AWS resource), Custom::* (for all custom resources), Custom::*logical_ID* `` (for a specific custom resource), ``AWS::*service_name* ::* (for all resources of a particular AWS service), and ``AWS::service_name ::resource_logical_ID `` (for a specific AWS resource).
If the list of resource types doesn't include a resource that you're creating, the stack creation fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for AWS CloudFormation-specific condition keys in IAM policies. For more information, see Controlling Access with AWS Identity and Access Management .
The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to create the stack. AWS CloudFormation uses the role's credentials to make calls on your behalf. AWS CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least privilege.
If you don't specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.
Determines what action will be taken if stack creation fails. This must be one of: DO_NOTHING, ROLLBACK, or DELETE. You can specify either OnFailure or DisableRollback , but not both.
Default: ROLLBACK
Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to the resources created in the stack. A maximum number of 50 tags can be specified.
The Tag type enables you to specify a key-value pair that can be used to store information about an AWS CloudFormation stack.
Required . A string used to identify this tag. You can specify a maximum of 128 characters for a tag key. Tags owned by Amazon Web Services (AWS) have the reserved prefix: aws: .
Required . A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.
A unique identifier for this CreateStack request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to create a stack with the same name. You might retry CreateStack requests to ensure that AWS CloudFormation successfully received them.
All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a CreateStack operation with the token token1 , then all the StackEvents generated by that operation will have ClientRequestToken set as token1 .
In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID , which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002 .
Whether to enable termination protection on the specified stack. If a user attempts to delete a stack with termination protection enabled, the operation fails and the stack remains unchanged. For more information, see Protecting a Stack From Being Deleted in the AWS CloudFormation User Guide . Termination protection is disabled on stacks by default.
For nested stacks , termination protection is set on the root stack and cannot be changed directly on the nested stack.

[REQUIRED]
The names of one or more regions where you want to create stack instances using the specified AWS account(s).
A list of stack set parameters whose values you want to override in the selected stack instances.
Any overridden parameter values will be applied to all stack instances in the specified accounts and regions. When specifying parameters and their values, be aware of how AWS CloudFormation sets parameter values during stack instance operations:
During stack set updates, any parameter values overridden for a stack instance are not updated, but retain their overridden value.
You can only override the parameter values that are specified in the stack set; to add or delete a parameter itself, use UpdateStackSet to update the stack set template.
The Parameter data type.
The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.
The input value associated with the parameter.
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
Preferences for how AWS CloudFormation performs this stack set operation.
The order of the regions in where you want to perform the stack operation.
The number of accounts, per region, for which this operation can fail before AWS CloudFormation stops the operation in that region. If the operation is stopped in a region, AWS CloudFormation doesn't attempt the operation in any subsequent regions.
Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage (but not both).
The percentage of accounts, per region, for which this stack operation can fail before AWS CloudFormation stops the operation in that region. If the operation is stopped in a region, AWS CloudFormation doesn't attempt the operation in any subsequent regions.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number.
Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage , but not both.
The maximum number of accounts in which to perform this operation at one time. This is dependent on the value of FailureToleranceCount —MaxConcurrentCount is at most one more than the FailureToleranceCount .
Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.
The maximum percentage of accounts in which to perform this operation at one time.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number. This is true except in cases where rounding down would result is zero. In this case, CloudFormation sets the number as one instead.
Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.
The unique identifier for this stack set operation.
The operation ID also functions as an idempotency token, to ensure that AWS CloudFormation performs the stack set operation only once, even if you retry the request multiple times. You might retry stack set operation requests to ensure that AWS CloudFormation successfully received them.
If you don't specify an operation ID, the SDK generates one automatically.
Repeating this stack set operation with a new operation ID retries all stack instances whose status is OUTDATED .

The name of the IAM execution role to use to create the stack set. If you do not specify an execution role, AWS CloudFormation uses the AWSCloudFormationStackSetExecutionRole role for the stack set operation.
Specify an IAM role only if you are using customized execution roles to control which stack resources users and groups can include in their stack sets.
A unique identifier for this CreateStackSet request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to create another stack set with the same name. You might retry CreateStackSet requests to ensure that AWS CloudFormation successfully received them.
If you don't specify an operation ID, the SDK generates one automatically.

[REQUIRED]
The name or the unique stack ID that is associated with the stack.
For stacks in the DELETE_FAILED state, a list of resource logical IDs that are associated with the resources you want to retain. During deletion, AWS CloudFormation deletes the stack but does not delete the retained resources.
Retaining resources is useful when you cannot delete a resource, such as a non-empty S3 bucket, but you want to delete the stack.
The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to delete the stack. AWS CloudFormation uses the role's credentials to make calls on your behalf.
If you don't specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.
A unique identifier for this DeleteStack request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to delete a stack with the same name. You might retry DeleteStack requests to ensure that AWS CloudFormation successfully received them.
All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a CreateStack operation with the token token1 , then all the StackEvents generated by that operation will have ClientRequestToken set as token1 .
In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID , which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002 .

Preferences for how AWS CloudFormation performs this stack set operation.
The order of the regions in where you want to perform the stack operation.
The number of accounts, per region, for which this operation can fail before AWS CloudFormation stops the operation in that region. If the operation is stopped in a region, AWS CloudFormation doesn't attempt the operation in any subsequent regions.
Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage (but not both).
The percentage of accounts, per region, for which this stack operation can fail before AWS CloudFormation stops the operation in that region. If the operation is stopped in a region, AWS CloudFormation doesn't attempt the operation in any subsequent regions.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number.
Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage , but not both.
The maximum number of accounts in which to perform this operation at one time. This is dependent on the value of FailureToleranceCount —MaxConcurrentCount is at most one more than the FailureToleranceCount .
Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.
The maximum percentage of accounts in which to perform this operation at one time.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number. This is true except in cases where rounding down would result is zero. In this case, CloudFormation sets the number as one instead.
Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.
[REQUIRED]
Removes the stack instances from the specified stack set, but doesn't delete the stacks. You can't reassociate a retained stack or add an existing, saved stack to a new stack set.
For more information, see Stack set operation options .
The unique identifier for this stack set operation.
If you don't specify an operation ID, the SDK generates one automatically.
The operation ID also functions as an idempotency token, to ensure that AWS CloudFormation performs the stack set operation only once, even if you retry the request multiple times. You can retry stack set operation requests to ensure that AWS CloudFormation successfully received them.
Repeating this stack set operation with a new operation ID retries all stack instances whose status is OUTDATED .

Response Structure
(dict) --
The output for the DescribeChangeSet action.
ChangeSetName (string) --
The name of the change set.
ChangeSetId (string) --
The ARN of the change set.
StackId (string) --
The ARN of the stack that is associated with the change set.
StackName (string) --
The name of the stack that is associated with the change set.
Description (string) --
Information about the change set.
Parameters (list) --
A list of Parameter structures that describes the input parameters and their values used to create the change set. For more information, see the Parameter data type.
(dict) --
The Parameter data type.
ParameterKey (string) --
The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.
ParameterValue (string) --
The input value associated with the parameter.
UsePreviousValue (boolean) --
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
ResolvedValue (string) --
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
CreationTime (datetime) --
The start time when the change set was created, in UTC.
ExecutionStatus (string) --
If the change set execution status is AVAILABLE , you can execute the change set. If you can’t execute the change set, the status indicates why. For example, a change set might be in an UNAVAILABLE state because AWS CloudFormation is still creating it or in an OBSOLETE state because the stack was already updated.
Status (string) --
The current status of the change set, such as CREATE_IN_PROGRESS , CREATE_COMPLETE , or FAILED .
StatusReason (string) --
A description of the change set's status. For example, if your attempt to create a change set failed, AWS CloudFormation shows the error message.
NotificationARNs (list) --
The ARNs of the Amazon Simple Notification Service (Amazon SNS) topics that will be associated with the stack if you execute the change set.
RollbackConfiguration (dict) --
The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.
RollbackTriggers (list) --
The triggers to monitor during stack creation or update actions.
By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:
If a specified trigger is missing, the entire stack operation fails and is rolled back.
(dict) --
A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.
Arn (string) --
The Amazon Resource Name (ARN) of the rollback trigger.
If a specified trigger is missing, the entire stack operation fails and is rolled back.
Type (string) --
The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.
MonitoringTimeInMinutes (integer) --
The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.
The default is 0 minutes.
If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack , for example) as necessary.
If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.
Capabilities (list) --
If you execute the change set, the list of capabilities that were explicitly acknowledged when the change set was created.
Tags (list) --
If you execute the change set, the tags that will be associated with the stack.
(dict) --
The Tag type enables you to specify a key-value pair that can be used to store information about an AWS CloudFormation stack.
Key (string) --
Required . A string used to identify this tag. You can specify a maximum of 128 characters for a tag key. Tags owned by Amazon Web Services (AWS) have the reserved prefix: aws: .
Value (string) --
Required . A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.
Changes (list) --
A list of Change structures that describes the resources AWS CloudFormation changes if you execute the change set.
(dict) --
The Change structure describes the changes AWS CloudFormation will perform if you execute the change set.
Type (string) --
The type of entity that AWS CloudFormation changes. Currently, the only entity type is Resource .
ResourceChange (dict) --
A ResourceChange structure that describes the resource and action that AWS CloudFormation will perform.
Action (string) --
The action that AWS CloudFormation takes on the resource, such as Add (adds a new resource), Modify (changes a resource), or Remove (deletes a resource).
LogicalResourceId (string) --
The resource's logical ID, which is defined in the stack's template.
PhysicalResourceId (string) --
The resource's physical ID (resource name). Resources that you are adding don't have physical IDs because they haven't been created.
ResourceType (string) --
The type of AWS CloudFormation resource, such as AWS::S3::Bucket .
Replacement (string) --
For the Modify action, indicates whether AWS CloudFormation will replace the resource by creating a new one and deleting the old one. This value depends on the value of the RequiresRecreation property in the ResourceTargetDefinition structure. For example, if the RequiresRecreation field is Always and the Evaluation field is Static , Replacement is True . If the RequiresRecreation field is Always and the Evaluation field is Dynamic , Replacement is Conditionally .
If you have multiple changes with different RequiresRecreation values, the Replacement value depends on the change with the most impact. A RequiresRecreation value of Always has the most impact, followed by Conditionally , and then Never .
Scope (list) --
For the Modify action, indicates which resource attribute is triggering this update, such as a change in the resource attribute's Metadata , Properties , or Tags .
Details (list) --
For the Modify action, a list of ResourceChangeDetail structures that describes the changes that AWS CloudFormation will make to the resource.
(dict) --
For a resource with Modify as the action, the ResourceChange structure describes the changes AWS CloudFormation will make to that resource.
Target (dict) --
A ResourceTargetDefinition structure that describes the field that AWS CloudFormation will change and whether the resource will be recreated.
Attribute (string) --
Indicates which resource attribute is triggering this update, such as a change in the resource attribute's Metadata , Properties , or Tags .
Name (string) --
If the Attribute value is Properties , the name of the property. For all other attributes, the value is null.
RequiresRecreation (string) --
If the Attribute value is Properties , indicates whether a change to this property causes the resource to be recreated. The value can be Never , Always , or Conditionally . To determine the conditions for a Conditionally recreation, see the update behavior for that property in the AWS CloudFormation User Guide.
Evaluation (string) --
Indicates whether AWS CloudFormation can determine the target value, and whether the target value will change before you execute a change set.
For Static evaluations, AWS CloudFormation can determine that the target value will change, and its value. For example, if you directly modify the InstanceType property of an EC2 instance, AWS CloudFormation knows that this property value will change, and its value, so this is a Static evaluation.
For Dynamic evaluations, cannot determine the target value because it depends on the result of an intrinsic function, such as a Ref or Fn::GetAtt intrinsic function, when the stack is updated. For example, if your template includes a reference to a resource that is conditionally recreated, the value of the reference (the physical ID of the resource) might change, depending on if the resource is recreated. If the resource is recreated, it will have a new physical ID, so all references to that resource will also be updated.
ChangeSource (string) --
The group to which the CausingEntity value belongs. There are five entity groups:
CausingEntity (string) --
The identity of the entity that triggered this change. This entity is a member of the group that is specified by the ChangeSource field. For example, if you modified the value of the KeyPairName parameter, the CausingEntity is the name of the parameter (KeyPairName ).
If the ChangeSource value is DirectModification , no value is given for CausingEntity .
NextToken (string) --
If the output exceeds 1 MB, a string that identifies the next page of changes. If there is no additional page, this value is null.
Returns information about a stack drift detection operation. A stack drift detection operation detects whether a stack's actual configuration differs, or has drifted , from it's expected configuration, as defined in the stack template and any values specified as template parameters. A stack is considered to have drifted if one or more of its resources have drifted. For more information on stack and resource drift, see Detecting Unregulated Configuration Changes to Stacks and Resources .
Use DetectStackDrift to initiate a stack drift detection operation. DetectStackDrift returns a StackDriftDetectionId you can use to monitor the progress of the operation using DescribeStackDriftDetectionStatus . Once the drift detection operation has completed, use DescribeStackResourceDrifts to return drift information about the stack and its resources.

In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID , which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002 .

Response Structure
(dict) --
StackResourceDrifts (list) --
Drift information for the resources that have been checked for drift in the specified stack. This includes actual and expected configuration values for resources where AWS CloudFormation detects drift.
For a given stack, there will be one StackResourceDrift for each stack resource that has been checked for drift. Resources that have not yet been checked for drift are not included. Resources that do not currently support drift detection are not checked, and so not included. For a list of resources that support drift detection, see Resources that Support Drift Detection .
(dict) --
Contains the drift information for a resource that has been checked for drift. This includes actual and expected property values for resources in which AWS CloudFormation has detected drift. Only resource properties explicitly defined in the stack template are checked for drift. For more information, see Detecting Unregulated Configuration Changes to Stacks and Resources .
Resources that do not currently support drift detection cannot be checked. For a list of resources that support drift detection, see Resources that Support Drift Detection .

Note
Only the first 100 resources will be returned. If your stack has more resources than this, you should use ListStackResources instead.
For deleted stacks, DescribeStackResources returns resource information for up to 90 days after the stack has been deleted.
You must specify either StackName or PhysicalResourceId , but not both. In addition, you can specify LogicalResourceId to filter the returned result. For more information about resources, the LogicalResourceId and PhysicalResourceId , go to the AWS CloudFormation User Guide .

The specified stack set operation.
OperationId (string) --
The unique ID of a stack set operation.
StackSetId (string) --
The ID of the stack set.
Action (string) --
The type of stack set operation: CREATE , UPDATE , or DELETE . Create and delete operations affect only the specified stack set instances that are associated with the specified stack set. Update operations affect both the stack set itself, as well as all associated stack set instances.
Status (string) --
The status of the operation.
OperationPreferences (dict) --
The preferences for how AWS CloudFormation performs this stack set operation.
RegionOrder (list) --
The order of the regions in where you want to perform the stack operation.
FailureToleranceCount (integer) --
The number of accounts, per region, for which this operation can fail before AWS CloudFormation stops the operation in that region. If the operation is stopped in a region, AWS CloudFormation doesn't attempt the operation in any subsequent regions.
Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage (but not both).
FailureTolerancePercentage (integer) --
The percentage of accounts, per region, for which this stack operation can fail before AWS CloudFormation stops the operation in that region. If the operation is stopped in a region, AWS CloudFormation doesn't attempt the operation in any subsequent regions.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number.
Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage , but not both.
MaxConcurrentCount (integer) --
The maximum number of accounts in which to perform this operation at one time. This is dependent on the value of FailureToleranceCount —MaxConcurrentCount is at most one more than the FailureToleranceCount .
Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.
MaxConcurrentPercentage (integer) --
The maximum percentage of accounts in which to perform this operation at one time.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number. This is true except in cases where rounding down would result is zero. In this case, CloudFormation sets the number as one instead.
Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.
RetainStacks (boolean) --
For stack set operations of action type DELETE , specifies whether to remove the stack instances from the specified stack set, but doesn't delete the stacks. You can't reassociate a retained stack, or add an existing, saved stack to a new stack set.
AdministrationRoleARN (string) --
The Amazon Resource Number (ARN) of the IAM role used to perform this stack set operation.
Use customized administrator roles to control which users or groups can manage specific stack sets within the same administrator account. For more information, see Define Permissions for Multiple Administrators in the AWS CloudFormation User Guide .
ExecutionRoleName (string) --
The name of the IAM execution role used to create or update the stack set.
Use customized execution roles to control which stack resources users and groups can include in their stack sets.
CreationTimestamp (datetime) --
The time at which the operation was initiated. Note that the creation times for the stack set operation might differ from the creation time of the individual stacks themselves. This is because AWS CloudFormation needs to perform preparatory work for the operation, such as dispatching the work to the requested regions, before actually creating the first stacks.
EndTimestamp (datetime) --
The time at which the stack set operation ended, across all accounts and regions specified. Note that this doesn't necessarily mean that the stack set operation was successful, or even attempted, in each account or region.
Returns the description for the specified stack; if no stack name was specified, then it returns the description for all the stacks created.
Note
If the stack does not exist, an AmazonCloudFormationException is returned.

UsePreviousValue (boolean) --
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
ResolvedValue (string) --
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
CreationTime (datetime) --
The time at which the stack was created.
DeletionTime (datetime) --
The time the stack was deleted.
LastUpdatedTime (datetime) --
The time the stack was last updated. This field will only be returned if the stack has been updated at least once.
RollbackConfiguration (dict) --
The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.
RollbackTriggers (list) --
The triggers to monitor during stack creation or update actions.
By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:
If a specified trigger is missing, the entire stack operation fails and is rolled back.
(dict) --
A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.
Arn (string) --
The Amazon Resource Name (ARN) of the rollback trigger.
If a specified trigger is missing, the entire stack operation fails and is rolled back.
Type (string) --
The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.
MonitoringTimeInMinutes (integer) --
The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.
The default is 0 minutes.
If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack , for example) as necessary.
If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.
StackStatus (string) --
Current status of the stack.
StackStatusReason (string) --
Success/failure message associated with the stack status.
DisableRollback (boolean) --
Boolean to enable or disable rollback on stack creation failures:

Value (string) --
Required . A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.
EnableTerminationProtection (boolean) --
Whether termination protection is enabled for the stack.
For nested stacks , termination protection is set on the root stack and cannot be changed directly on the nested stack. For more information, see Protecting a Stack From Being Deleted in the AWS CloudFormation User Guide .
ParentId (string) --
For nested stacks--stacks created as resources for another stack--the stack ID of the direct parent of this stack. For the first level of nested stacks, the root stack is also the parent stack.
For more information, see Working with Nested Stacks in the AWS CloudFormation User Guide .
RootId (string) --
For nested stacks--stacks created as resources for another stack--the stack ID of the the top-level stack to which the nested stack ultimately belongs.
For more information, see Working with Nested Stacks in the AWS CloudFormation User Guide .
DriftInformation (dict) --
Information on whether a stack's actual configuration differs, or has drifted , from it's expected configuration, as defined in the stack template and any values specified as template parameters. For more information, see Detecting Unregulated Configuration Changes to Stacks and Resources .
StackDriftStatus (string) --

LastCheckTimestamp (datetime) --
Most recent time when a drift detection operation was initiated on the stack, or any of its individual resources that support drift detection.
NextToken (string) --
If the output exceeds 1 MB in size, a string that identifies the next page of stacks. If no additional page exists, this value is null.
Detects whether a stack's actual configuration differs, or has drifted , from it's expected configuration, as defined in the stack template and any values specified as template parameters. For each resource in the stack that supports drift detection, AWS CloudFormation compares the actual configuration of the resource with its expected template configuration. Only resource properties explicitly defined in the stack template are checked for drift. A stack is considered to have drifted if one or more of its resources differ from their expected template configurations. For more information, see Detecting Unregulated Configuration Changes to Stacks and Resources .
Use DetectStackDrift to detect drift on all supported resources for a given stack, or DetectStackResourceDrift to detect drift on individual resources.
For a list of stack resources that currently support drift detection, see Resources that Support Drift Detection .
DetectStackDrift can take up to several minutes, depending on the number of resources contained within the stack. Use DescribeStackDriftDetectionStatus to monitor the progress of a detect stack drift operation. Once the drift detection operation has completed, use DescribeStackResourceDrifts to return drift information about the stack and its resources.
When detecting drift on a stack, AWS CloudFormation does not detect drift on any nested stacks belonging to that stack. Perform DetectStackDrift directly on the nested stack itself.

Updates a stack using the input information that was provided when the specified change set was created. After the call successfully completes, AWS CloudFormation starts updating the stack. Use the DescribeStacks action to view the status of the update.
When you execute a change set, AWS CloudFormation deletes all other change sets associated with the stack because they aren't valid for the updated stack.
If a stack policy is associated with the stack, AWS CloudFormation enforces the policy during the update. You can't specify a temporary stack policy that overrides the current policy.

[REQUIRED]
The name or unique stack ID of the stack to update.
Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. (For more information, go to Template Anatomy in the AWS CloudFormation User Guide.)
Conditional: You must specify only one of the following parameters: TemplateBody , TemplateURL , or set the UsePreviousTemplate to true .
Location of file containing the template body. The URL must point to a template that is located in an Amazon S3 bucket. For more information, go to Template Anatomy in the AWS CloudFormation User Guide.
Conditional: You must specify only one of the following parameters: TemplateBody , TemplateURL , or set the UsePreviousTemplate to true .
Reuse the existing template that is associated with the stack that you are updating.
Conditional: You must specify only one of the following parameters: TemplateBody , TemplateURL , or set the UsePreviousTemplate to true .
Structure containing the temporary overriding stack policy body. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both.
If you want to update protected resources, specify a temporary overriding stack policy during this update. If you do not specify a stack policy, the current policy that is associated with the stack will be used.
Location of a file containing the temporary overriding stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both.
If you want to update protected resources, specify a temporary overriding stack policy during this update. If you do not specify a stack policy, the current policy that is associated with the stack will be used.
A list of Parameter structures that specify input parameters for the stack. For more information, see the Parameter data type.
The Parameter data type.
The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.
The input value associated with the parameter.
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
A list of values that you must specify before AWS CloudFormation can update certain stacks. Some stack templates might include resources that can affect permissions in your AWS account, for example, by creating new AWS Identity and Access Management (IAM) users. For those stacks, you must explicitly acknowledge their capabilities by specifying this parameter.
The only valid values are CAPABILITY_IAM and CAPABILITY_NAMED_IAM . The following resources require you to specify this parameter: AWS::IAM::AccessKey , AWS::IAM::Group , AWS::IAM::InstanceProfile , AWS::IAM::Policy , AWS::IAM::Role , AWS::IAM::User , and AWS::IAM::UserToGroupAddition . If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.
If you have IAM resources, you can specify either capability. If you have IAM resources with custom names, you must specify CAPABILITY_NAMED_IAM . If you don't specify this parameter, this action returns an InsufficientCapabilities error.
For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates .
The template resource types that you have permissions to work with for this update stack action, such as AWS::EC2::Instance , AWS::EC2::* , or Custom::MyCustomInstance .
If the list of resource types doesn't include a resource that you're updating, the stack update fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for AWS CloudFormation-specific condition keys in IAM policies. For more information, see Controlling Access with AWS Identity and Access Management .
The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to update the stack. AWS CloudFormation uses the role's credentials to make calls on your behalf. AWS CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least privilege.
If you don't specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.
The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.
The triggers to monitor during stack creation or update actions.
By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:
If a specified trigger is missing, the entire stack operation fails and is rolled back.
A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.
The Amazon Resource Name (ARN) of the rollback trigger.
If a specified trigger is missing, the entire stack operation fails and is rolled back.
The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.
The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.
The default is 0 minutes.
If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack , for example) as necessary.
If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.
Structure containing a new stack policy body. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.
You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you do not specify a stack policy, the current policy that is associated with the stack is unchanged.
Location of a file containing the updated stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.
You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you do not specify a stack policy, the current policy that is associated with the stack is unchanged.
Amazon Simple Notification Service topic Amazon Resource Names (ARNs) that AWS CloudFormation associates with the stack. Specify an empty list to remove all notification topics.
Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to supported resources in the stack. You can specify a maximum number of 50 tags.
If you don't specify this parameter, AWS CloudFormation doesn't modify the stack's tags. If you specify an empty value, AWS CloudFormation removes all associated tags.
The Tag type enables you to specify a key-value pair that can be used to store information about an AWS CloudFormation stack.
Required . A string used to identify this tag. You can specify a maximum of 128 characters for a tag key. Tags owned by Amazon Web Services (AWS) have the reserved prefix: aws: .
Required . A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.
A unique identifier for this UpdateStack request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to update a stack with the same name. You might retry UpdateStack requests to ensure that AWS CloudFormation successfully received them.
All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a CreateStack operation with the token token1 , then all the StackEvents generated by that operation will have ClientRequestToken set as token1 .
In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID , which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002 .

Updates the parameter values for stack instances for the specified accounts, within the specified regions. A stack instance refers to a stack in a specific account and region.
You can only update stack instances in regions and accounts where they already exist; to create additional stack instances, use CreateStackInstances .
During stack set updates, any parameters overridden for a stack instance are not updated, but retain their overridden value.
You can only update the parameter values that are specified in the stack set; to add or delete a parameter itself, use UpdateStackSet to update the stack set template. If you add a parameter to a template, before you can override the parameter value specified in the stack set you must first use UpdateStackSet to update all stack instances with the updated template and parameter value specified in the stack set. Once a stack instance has been updated with the new parameter, you can then override the parameter value using UpdateStackInstances .

[REQUIRED]
The names of one or more regions in which you want to update parameter values for stack instances. The overridden parameter values will be applied to all stack instances in the specified accounts and regions.
A list of input parameters whose values you want to update for the specified stack instances.
Any overridden parameter values will be applied to all stack instances in the specified accounts and regions. When specifying parameters and their values, be aware of how AWS CloudFormation sets parameter values during stack instance update operations:
During stack set updates, any parameter values overridden for a stack instance are not updated, but retain their overridden value.
You can only override the parameter values that are specified in the stack set; to add or delete a parameter itself, use UpdateStackSet to update the stack set template. If you add a parameter to a template, before you can override the parameter value specified in the stack set you must first use UpdateStackSet to update all stack instances with the updated template and parameter value specified in the stack set. Once a stack instance has been updated with the new parameter, you can then override the parameter value using UpdateStackInstances .
The Parameter data type.
The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.
The input value associated with the parameter.
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
Preferences for how AWS CloudFormation performs this stack set operation.
The order of the regions in where you want to perform the stack operation.
The number of accounts, per region, for which this operation can fail before AWS CloudFormation stops the operation in that region. If the operation is stopped in a region, AWS CloudFormation doesn't attempt the operation in any subsequent regions.
Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage (but not both).
The percentage of accounts, per region, for which this stack operation can fail before AWS CloudFormation stops the operation in that region. If the operation is stopped in a region, AWS CloudFormation doesn't attempt the operation in any subsequent regions.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number.
Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage , but not both.
The maximum number of accounts in which to perform this operation at one time. This is dependent on the value of FailureToleranceCount —MaxConcurrentCount is at most one more than the FailureToleranceCount .
Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.
The maximum percentage of accounts in which to perform this operation at one time.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number. This is true except in cases where rounding down would result is zero. In this case, CloudFormation sets the number as one instead.
Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.
Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.
The unique identifier for this stack set operation.
The operation ID also functions as an idempotency token, to ensure that AWS CloudFormation performs the stack set operation only once, even if you retry the request multiple times. You might retry stack set operation requests to ensure that AWS CloudFormation successfully received them.
If you don't specify an operation ID, the SDK generates one automatically.

A list of values that you must specify before AWS CloudFormation can create certain stack sets. Some stack set templates might include resources that can affect permissions in your AWS account—for example, by creating new AWS Identity and Access Management (IAM) users.

The key-value pairs to associate with this stack set and the stacks created from it. AWS CloudFormation also propagates these tags to supported resources that are created in the stacks. You can specify a maximum number of 50 tags.
If you specify tags for this parameter, those tags replace any list of tags that are currently associated with this stack set. This means:
If you specify new tags as part of an UpdateStackSet action, AWS CloudFormation checks to see if you have the required IAM permission to tag resources. If you omit tags that are currently associated with the stack set from the list of tags you specify, AWS CloudFormation assumes that you want to remove those tags from the stack set, and checks to see if you have permission to untag resources. If you don't have the necessary permission(s), the entire UpdateStackSet action fails with an access denied error, and the stack set is not updated.
The Tag type enables you to specify a key-value pair that can be used to store information about an AWS CloudFormation stack.
Required . A string used to identify this tag. You can specify a maximum of 128 characters for a tag key. Tags owned by Amazon Web Services (AWS) have the reserved prefix: aws: .

The Amazon Resource Number (ARN) of the IAM role to use to update this stack set.
Specify an IAM role only if you are using customized administrator roles to control which users or groups can manage specific stack sets within the same administrator account. For more information, see Define Permissions for Multiple Administrators in the AWS CloudFormation User Guide .
If you specify a customized administrator role, AWS CloudFormation uses that role to update the stack. If you do not specify a customized administrator role, AWS CloudFormation performs the update using the role previously associated with the stack set, so long as you have permissions to perform operations on the stack set.
The name of the IAM execution role to use to update the stack set. If you do not specify an execution role, AWS CloudFormation uses the AWSCloudFormationStackSetExecutionRole role for the stack set operation.
Specify an IAM role only if you are using customized execution roles to control which stack resources users and groups can include in their stack sets.

To update all the stack instances associated with this stack set, do not specify the Accounts or Regions properties.
If the stack set update includes changes to the template (that is, if the TemplateBody or TemplateURL properties are specified), or the Parameters property, AWS CloudFormation marks all stack instances with a status of OUTDATED prior to updating the stack instances in the specified accounts and regions. If the stack set update does not include changes to the template or parameters, AWS CloudFormation updates the stack instances in the specified accounts and regions, while leaving all other stack instances with their existing stack instance status.

For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002 .

The unique ID of the change set.
Description (string) --
A user-defined description associated with the stack.
Parameters (list) --
A list of Parameter structures.
(dict) --
The Parameter data type.
ParameterKey (string) --
The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.
ParameterValue (string) --
The input value associated with the parameter.
UsePreviousValue (boolean) --
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
ResolvedValue (string) --
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
CreationTime (datetime) --
The time at which the stack was created.
DeletionTime (datetime) --
The time the stack was deleted.
LastUpdatedTime (datetime) --
The time the stack was last updated. This field will only be returned if the stack has been updated at least once.
RollbackConfiguration (dict) --
The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.
RollbackTriggers (list) --
The triggers to monitor during stack creation or update actions.
By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:
If a specified trigger is missing, the entire stack operation fails and is rolled back.
(dict) --
A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.
Arn (string) --
The Amazon Resource Name (ARN) of the rollback trigger.
If a specified trigger is missing, the entire stack operation fails and is rolled back.
Type (string) --
The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.
MonitoringTimeInMinutes (integer) --
The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.
The default is 0 minutes.
If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack , for example) as necessary.
If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.

[REQUIRED]
The name that is associated with the stack. The name must be unique in the region in which you are creating the stack.
Note
A stack name can contain only alphanumeric characters (case sensitive) and hyphens. It must start with an alphabetic character and cannot be longer than 128 characters.
Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. For more information, go to Template Anatomy in the AWS CloudFormation User Guide.
Conditional: You must specify either the TemplateBody or the TemplateURL parameter, but not both.
Location of file containing the template body. The URL must point to a template (max size: 460,800 bytes) that is located in an Amazon S3 bucket. For more information, go to the Template Anatomy in the AWS CloudFormation User Guide.
Conditional: You must specify either the TemplateBody or the TemplateURL parameter, but not both.
A list of Parameter structures that specify input parameters for the stack. For more information, see the Parameter data type.
The Parameter data type.
The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.
The input value associated with the parameter.
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
Set to true to disable rollback of the stack if stack creation failed. You can specify either DisableRollback or OnFailure , but not both.
Default: false
The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.
The triggers to monitor during stack creation or update actions.
By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:
If a specified trigger is missing, the entire stack operation fails and is rolled back.
A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.
The Amazon Resource Name (ARN) of the rollback trigger.
If a specified trigger is missing, the entire stack operation fails and is rolled back.
The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.
The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.
The default is 0 minutes.
If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack , for example) as necessary.
If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.
The Simple Notification Service (SNS) topic ARNs to publish stack related events. You can find your SNS topic ARNs using the SNS console or your Command Line Interface (CLI).
A list of values that you must specify before AWS CloudFormation can create certain stacks. Some stack templates might include resources that can affect permissions in your AWS account, for example, by creating new AWS Identity and Access Management (IAM) users. For those stacks, you must explicitly acknowledge their capabilities by specifying this parameter.
The only valid values are CAPABILITY_IAM and CAPABILITY_NAMED_IAM . The following resources require you to specify this parameter: AWS::IAM::AccessKey , AWS::IAM::Group , AWS::IAM::InstanceProfile , AWS::IAM::Policy , AWS::IAM::Role , AWS::IAM::User , and AWS::IAM::UserToGroupAddition . If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.
If you have IAM resources, you can specify either capability. If you have IAM resources with custom names, you must specify CAPABILITY_NAMED_IAM . If you don't specify this parameter, this action returns an InsufficientCapabilities error.
For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates .
The template resource types that you have permissions to work with for this create stack action, such as AWS::EC2::Instance , AWS::EC2::* , or Custom::MyCustomInstance . Use the following syntax to describe template resource types: AWS::* (for all AWS resource), Custom::* (for all custom resources), Custom::*logical_ID* `` (for a specific custom resource), ``AWS::*service_name* ::* (for all resources of a particular AWS service), and ``AWS::service_name ::resource_logical_ID `` (for a specific AWS resource).
If the list of resource types doesn't include a resource that you're creating, the stack creation fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for AWS CloudFormation-specific condition keys in IAM policies. For more information, see Controlling Access with AWS Identity and Access Management .
The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to create the stack. AWS CloudFormation uses the role's credentials to make calls on your behalf. AWS CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least privilege.
If you don't specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.
Determines what action will be taken if stack creation fails. This must be one of: DO_NOTHING, ROLLBACK, or DELETE. You can specify either OnFailure or DisableRollback , but not both.
Default: ROLLBACK
Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to the resources created in the stack. A maximum number of 50 tags can be specified.
The Tag type enables you to specify a key-value pair that can be used to store information about an AWS CloudFormation stack.
Required . A string used to identify this tag. You can specify a maximum of 128 characters for a tag key. Tags owned by Amazon Web Services (AWS) have the reserved prefix: aws: .
Required . A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.
A unique identifier for this CreateStack request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to create a stack with the same name. You might retry CreateStack requests to ensure that AWS CloudFormation successfully received them.
All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a CreateStack operation with the token token1 , then all the StackEvents generated by that operation will have ClientRequestToken set as token1 .
In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID , which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002 .
Whether to enable termination protection on the specified stack. If a user attempts to delete a stack with termination protection enabled, the operation fails and the stack remains unchanged. For more information, see Protecting a Stack From Being Deleted in the AWS CloudFormation User Guide . Termination protection is disabled on stacks by default.
For nested stacks , termination protection is set on the root stack and cannot be changed directly on the nested stack.

(dict) --
The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.
RollbackTriggers (list) --
The triggers to monitor during stack creation or update actions.
By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:
If a specified trigger is missing, the entire stack operation fails and is rolled back.

The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.
The default is 0 minutes.
If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack , for example) as necessary.
If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.
(string) --

Actions
Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.
Cancels an update on the specified stack. If the call completes successfully, the stack rolls back the update and reverts to the previous stack configuration.
Note
You can cancel only stacks that are in the UPDATE_IN_PROGRESS state.
See also: AWS API Documentation
Request Syntax
response = stack.cancel_update(
ClientRequestToken='string'
)
Deletes a specified stack. Once the call completes successfully, stack deletion starts. Deleted stacks do not show up in the DescribeStacks API if the deletion has been completed successfully.
See also: AWS API Documentation
Request Syntax
response = stack.delete(
RetainResources=[
'string',
],
RoleARN='string',
ClientRequestToken='string'
)
For stacks in the DELETE_FAILED state, a list of resource logical IDs that are associated with the resources you want to retain. During deletion, AWS CloudFormation deletes the stack but does not delete the retained resources.
Retaining resources is useful when you cannot delete a resource, such as a non-empty S3 bucket, but you want to delete the stack.
The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to delete the stack. AWS CloudFormation uses the role's credentials to make calls on your behalf.
If you don't specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.
A unique identifier for this DeleteStack request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to delete a stack with the same name. You might retry DeleteStack requests to ensure that AWS CloudFormation successfully received them.
All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a CreateStack operation with the token token1 , then all the StackEvents generated by that operation will have ClientRequestToken set as token1 .
In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID , which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002 .
None
Returns a list of all the available sub-resources for this Resource.

Structure containing the temporary overriding stack policy body. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both.
If you want to update protected resources, specify a temporary overriding stack policy during this update. If you do not specify a stack policy, the current policy that is associated with the stack will be used.
Location of a file containing the temporary overriding stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. You can specify either the StackPolicyDuringUpdateBody or the StackPolicyDuringUpdateURL parameter, but not both.
If you want to update protected resources, specify a temporary overriding stack policy during this update. If you do not specify a stack policy, the current policy that is associated with the stack will be used.
A list of Parameter structures that specify input parameters for the stack. For more information, see the Parameter data type.
The Parameter data type.
The key associated with the parameter. If you don't specify a key and value for a particular parameter, AWS CloudFormation uses the default value that is specified in your template.
The input value associated with the parameter.
During a stack update, use the existing parameter value that the stack is using for a given parameter key. If you specify true , do not specify a parameter value.
Read-only. The value that corresponds to a Systems Manager parameter key. This field is returned only for ` SSM parameter types <http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html#aws-ssm-parameter-types>`__ in the template.
A list of values that you must specify before AWS CloudFormation can update certain stacks. Some stack templates might include resources that can affect permissions in your AWS account, for example, by creating new AWS Identity and Access Management (IAM) users. For those stacks, you must explicitly acknowledge their capabilities by specifying this parameter.
The only valid values are CAPABILITY_IAM and CAPABILITY_NAMED_IAM . The following resources require you to specify this parameter: AWS::IAM::AccessKey , AWS::IAM::Group , AWS::IAM::InstanceProfile , AWS::IAM::Policy , AWS::IAM::Role , AWS::IAM::User , and AWS::IAM::UserToGroupAddition . If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.
If you have IAM resources, you can specify either capability. If you have IAM resources with custom names, you must specify CAPABILITY_NAMED_IAM . If you don't specify this parameter, this action returns an InsufficientCapabilities error.
For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates .
The template resource types that you have permissions to work with for this update stack action, such as AWS::EC2::Instance , AWS::EC2::* , or Custom::MyCustomInstance .
If the list of resource types doesn't include a resource that you're updating, the stack update fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for AWS CloudFormation-specific condition keys in IAM policies. For more information, see Controlling Access with AWS Identity and Access Management .
The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to update the stack. AWS CloudFormation uses the role's credentials to make calls on your behalf. AWS CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least privilege.
If you don't specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.
The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.
The triggers to monitor during stack creation or update actions.
By default, AWS CloudFormation saves the rollback triggers specified for a stack and applies them to any subsequent update operations for the stack, unless you specify otherwise. If you do specify rollback triggers for this parameter, those triggers replace any list of triggers previously specified for the stack. This means:
If a specified trigger is missing, the entire stack operation fails and is rolled back.
A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.
The Amazon Resource Name (ARN) of the rollback trigger.
If a specified trigger is missing, the entire stack operation fails and is rolled back.
The resource type of the rollback trigger. Currently, AWS::CloudWatch::Alarm is the only supported resource type.
The amount of time, in minutes, during which CloudFormation should monitor all the rollback triggers after the stack creation or update operation deploys all necessary resources.
The default is 0 minutes.
If you specify a monitoring period but do not specify any rollback triggers, CloudFormation still waits the specified period of time before cleaning up old resources after update operations. You can use this monitoring period to perform any manual stack validation desired, and manually cancel the stack creation or update (using CancelUpdateStack , for example) as necessary.
If you specify 0 for this parameter, CloudFormation still monitors the specified rollback triggers during stack creation and update operations. Then, for update operations, it begins disposing of old resources immediately once the operation completes.
Structure containing a new stack policy body. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.
You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you do not specify a stack policy, the current policy that is associated with the stack is unchanged.
Location of a file containing the updated stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.
You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you do not specify a stack policy, the current policy that is associated with the stack is unchanged.
Amazon Simple Notification Service topic Amazon Resource Names (ARNs) that AWS CloudFormation associates with the stack. Specify an empty list to remove all notification topics.
Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to supported resources in the stack. You can specify a maximum number of 50 tags.
If you don't specify this parameter, AWS CloudFormation doesn't modify the stack's tags. If you specify an empty value, AWS CloudFormation removes all associated tags.
The Tag type enables you to specify a key-value pair that can be used to store information about an AWS CloudFormation stack.
Required . A string used to identify this tag. You can specify a maximum of 128 characters for a tag key. Tags owned by Amazon Web Services (AWS) have the reserved prefix: aws: .
Required . A string containing the value for this tag. You can specify a maximum of 256 characters for a tag value.
A unique identifier for this UpdateStack request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to update a stack with the same name. You might retry UpdateStack requests to ensure that AWS CloudFormation successfully received them.
All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations.
