update_stack_set¶

CloudFormation.Client.update_stack_set(**kwargs)¶

Updates the StackSet and associated stack instances in the specified accounts and Amazon Web Services Regions.

Even if the StackSet operation created by updating the StackSet fails (completely or partially, below or above a specified failure tolerance), the StackSet is updated with your changes. Subsequent CreateStackInstances calls on the specified StackSet use the updated StackSet.

Note

The maximum number of organizational unit (OUs) supported by a UpdateStackSet operation is 50.

If you need more than 50, consider the following options:

Batch processing: If you don’t want to expose your OU hierarchy, split up the operations into multiple calls with less than 50 OUs each.
Parent OU strategy: If you don’t mind exposing the OU hierarchy, target a parent OU that contains all desired child OUs.

Parameters:

StackSetName (string) –
[REQUIRED]

The name or unique ID of the StackSet that you want to update.
Description (string) – A brief description of updates that you are making.
TemplateBody (string) –
The structure that contains the template body, with a minimum length of 1 byte and a maximum length of 51,200 bytes.

Conditional: You must specify only one of the following parameters: TemplateBody or TemplateURL—or set UsePreviousTemplate to true.
TemplateURL (string) –
The URL of a file that contains the template body. The URL must point to a template (maximum size: 1 MB) that is located in an Amazon S3 bucket or a Systems Manager document. The location for an Amazon S3 bucket must start with https://. S3 static website URLs are not supported.

Conditional: You must specify only one of the following parameters: TemplateBody or TemplateURL—or set UsePreviousTemplate to true.
UsePreviousTemplate (boolean) –
Use the existing template that’s associated with the StackSet that you’re updating.

Conditional: You must specify only one of the following parameters: TemplateBody or TemplateURL—or set UsePreviousTemplate to true.
Parameters (list) –
A list of input parameters for the StackSet template.
- (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, CloudFormation uses the default value that’s 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 Systems Manager parameter types in the template. For more information, see Specify existing resources at runtime with CloudFormation-supplied parameter types in the CloudFormation User Guide.
Capabilities (list) –
In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for CloudFormation to update the StackSet and its associated stack instances.
- CAPABILITY_IAM and CAPABILITY_NAMED_IAM Some stack templates might include resources that can affect permissions in your Amazon Web Services account, for example, by creating new IAM users. For those stacks sets, you must explicitly acknowledge this by specifying one of these capabilities. The following IAM resources require you to specify either the CAPABILITY_IAM or CAPABILITY_NAMED_IAM capability.
  - 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 either of these capabilities, CloudFormation returns an InsufficientCapabilities error.
If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.
For more information, see Acknowledging IAM resources in CloudFormation templates.
- CAPABILITY_AUTO_EXPAND Some templates reference macros. If your StackSet template references one or more macros, you must update the StackSet directly from the processed template, without first reviewing the resulting changes in a change set. To update the StackSet directly, you must acknowledge this capability. For more information, see Perform custom processing on CloudFormation templates with template macros.
Warning
StackSets with service-managed permissions do not currently support the use of macros in templates. (This includes the AWS::Include and AWS::Serverless transforms, which are macros hosted by CloudFormation.) Even if you specify this capability for a StackSet with service-managed permissions, if you reference a macro in your template the StackSet operation will fail.
- (string) –
Tags (list) –
The key-value pairs to associate with this StackSet and the stacks created from it. 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 StackSet. This means:
- If you don’t specify this parameter, CloudFormation doesn’t modify the stack’s tags.
- If you specify any tags using this parameter, you must specify all the tags that you want associated with this StackSet, even tags you’ve specified before (for example, when creating the StackSet or during a previous update of the StackSet.). Any tags that you don’t include in the updated list of tags are removed from the StackSet, and therefore from the stacks and resources as well.
- If you specify an empty value, CloudFormation removes all currently associated tags.
If you specify new tags as part of an UpdateStackSet action, CloudFormation checks to see if you have the required IAM permission to tag resources. If you omit tags that are currently associated with the StackSet from the list of tags you specify, CloudFormation assumes that you want to remove those tags from the StackSet, 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 StackSet is not updated.
- (dict) –
  
  The Tag type enables you to specify a key-value pair that can be used to store information about an 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 have the reserved prefix: aws:.
  - Value (string) – [REQUIRED]
    
    A string that contains the value for this tag. You can specify a maximum of 256 characters for a tag value.
OperationPreferences (dict) –
Preferences for how CloudFormation performs this StackSet operation.
- RegionConcurrencyType (string) –
  
  The concurrency type of deploying StackSets operations in Regions, could be in parallel or one Region at a time.
- RegionOrder (list) –
  
  The order of the Regions where you want to perform the stack operation.
  - (string) –
- FailureToleranceCount (integer) –
  
  The number of accounts per Region this operation can fail in before CloudFormation stops the operation in that Region. If the operation is stopped in a Region, CloudFormation doesn’t attempt the operation in any subsequent Regions.
  
  You can specify either FailureToleranceCount or FailureTolerancePercentage, but not both.
  
  By default, 0 is specified.
- FailureTolerancePercentage (integer) –
  
  The percentage of accounts per Region this stack operation can fail in before CloudFormation stops the operation in that Region. If the operation is stopped in a Region, CloudFormation doesn’t attempt the operation in any subsequent Regions.
  
  When calculating the number of accounts based on the specified percentage, CloudFormation rounds down to the next whole number.
  
  You can specify either FailureToleranceCount or FailureTolerancePercentage, but not both.
  
  By default, 0 is specified.
- MaxConcurrentCount (integer) –
  
  The maximum number of accounts in which to perform this operation at one time. This can depend on the value of FailureToleranceCount depending on your ConcurrencyMode. MaxConcurrentCount is at most one more than the FailureToleranceCount if you’re using STRICT_FAILURE_TOLERANCE.
  
  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.
  
  You can specify either MaxConcurrentCount or MaxConcurrentPercentage, but not both.
  
  By default, 1 is specified.
- 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, 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.
  
  You can specify either MaxConcurrentCount or MaxConcurrentPercentage, but not both.
  
  By default, 1 is specified.
- ConcurrencyMode (string) –
  
  Specifies how the concurrency level behaves during the operation execution.
  - STRICT_FAILURE_TOLERANCE: This option dynamically lowers the concurrency level to ensure the number of failed accounts never exceeds the value of FailureToleranceCount +1. The initial actual concurrency is set to the lower of either the value of the MaxConcurrentCount, or the value of FailureToleranceCount +1. The actual concurrency is then reduced proportionally by the number of failures. This is the default behavior. If failure tolerance or Maximum concurrent accounts are set to percentages, the behavior is similar.
  - SOFT_FAILURE_TOLERANCE: This option decouples FailureToleranceCount from the actual concurrency. This allows StackSet operations to run at the concurrency level set by the MaxConcurrentCount value, or MaxConcurrentPercentage, regardless of the number of failures.
AdministrationRoleARN (string) –
[Self-managed permissions] The Amazon Resource Name (ARN) of the IAM role to use to update this StackSet.

Specify an IAM role only if you are using customized administrator roles to control which users or groups can manage specific StackSets within the same administrator account. For more information, see Grant self-managed permissions in the CloudFormation User Guide.

If you specified a customized administrator role when you created the StackSet, you must specify a customized administrator role, even if it is the same customized administrator role used with this StackSet previously.
ExecutionRoleName (string) –
[Self-managed permissions] The name of the IAM execution role to use to update the stack set. If you do not specify an execution role, CloudFormation uses the AWSCloudFormationStackSetExecutionRole role for the StackSet 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 StackSets.

If you specify a customized execution role, CloudFormation uses that role to update the stack. If you do not specify a customized execution role, CloudFormation performs the update using the role previously associated with the StackSet, so long as you have permissions to perform operations on the StackSet.
DeploymentTargets (dict) –
[Service-managed permissions] The Organizations accounts in which to update associated stack instances.

To update all the stack instances associated with this StackSet, do not specify DeploymentTargets or Regions.

If the StackSet update includes changes to the template (that is, if TemplateBody or TemplateURL is specified), or the Parameters, CloudFormation marks all stack instances with a status of OUTDATED prior to updating the stack instances in the specified accounts and Amazon Web Services Regions. If the StackSet update doesn’t include changes to the template or parameters, CloudFormation updates the stack instances in the specified accounts and Regions, while leaving all other stack instances with their existing stack instance status.
- Accounts (list) –
  
  The Amazon Web Services account IDs where you want to perform stack operations. How these accounts are used depends on the AccountFilterType property.
  
  If you have many account numbers, you can provide those accounts using the AccountsUrl property instead.
  - (string) –
- AccountsUrl (string) –
  
  The Amazon S3 URL path to a file that contains a list of Amazon Web Services account IDs. The file format must be either .csv or .txt, and the data can be comma-separated or new-line-separated. There is currently a 10MB limit for the data (approximately 800,000 accounts).
  
  This property serves the same purpose as Accounts but allows you to specify a large number of accounts.
- OrganizationalUnitIds (list) –
  
  The organization root ID or organizational unit (OU) IDs where you want to perform stack operations. CloudFormation will perform operations on accounts within these OUs and their child OUs.
  - (string) –
- AccountFilterType (string) –
  
  Refines which accounts will have stack operations performed on them by specifying how to use the Accounts and OrganizationalUnitIds properties together.
  
  The following values determine how CloudFormation selects target accounts:
  - INTERSECTION: Performs stack operations only on specific individual accounts within the selected OUs. Only accounts that are both specified in the Accounts property and belong to the specified OUs will be targeted.
  - DIFFERENCE: Performs stack operations on all accounts in the selected OUs except for specific accounts listed in the Accounts property. This enables you to exclude certain accounts within an OU, such as suspended accounts.
  - UNION: Performs stack operations on the specified OUs plus additional individual accounts listed in the Accounts property. This is the default value if AccountFilterType is not provided. This lets you target an entire OU and individual accounts from a different OU in one request. Note that UNION is not supported for CreateStackInstances operations.
  - NONE: Performs stack operations on all accounts in the specified organizational units (OUs).
PermissionModel (string) –
Describes how the IAM roles required for StackSet operations are created. You cannot modify PermissionModel if there are stack instances associated with your stack set.
- With self-managed permissions, you must create the administrator and execution roles required to deploy to target accounts. For more information, see Grant self-managed permissions.
- With service-managed permissions, StackSets automatically creates the IAM roles required to deploy to accounts managed by Organizations. For more information, see Activate trusted access for StackSets with Organizations.
AutoDeployment (dict) –
[Service-managed permissions] Describes whether StackSets automatically deploys to Organizations accounts that are added to a target organization or organizational unit (OU). For more information, see Enable or disable automatic deployments for StackSets in Organizations in the CloudFormation User Guide.

If you specify AutoDeployment, don’t specify DeploymentTargets or Regions.
- Enabled (boolean) –
  
  If set to true, StackSets automatically deploys additional stack instances to Organizations accounts that are added to a target organization or organizational unit (OU) in the specified Regions. If an account is removed from a target organization or OU, StackSets deletes stack instances from the account in the specified Regions.
- RetainStacksOnAccountRemoval (boolean) –
  
  If set to true, stack resources are retained when an account is removed from a target organization or OU. If set to false, stack resources are deleted. Specify only if Enabled is set to True.
OperationId (string) –
The unique ID for this StackSet operation.

The operation ID also functions as an idempotency token, to ensure that CloudFormation performs the StackSet operation only once, even if you retry the request multiple times. You might retry StackSet operation requests to ensure that CloudFormation successfully received them.

If you don’t specify an operation ID, CloudFormation generates one automatically.

Repeating this StackSet operation with a new operation ID retries all stack instances whose status is OUTDATED.

This field is autopopulated if not provided.
Accounts (list) –
[Self-managed permissions] The accounts in which to update associated stack instances. If you specify accounts, you must also specify the Amazon Web Services Regions in which to update StackSet instances.

To update all the stack instances associated with this StackSet, don’t specify the Accounts or Regions properties.

If the StackSet update includes changes to the template (that is, if the TemplateBody or TemplateURL properties are specified), or the Parameters property, CloudFormation marks all stack instances with a status of OUTDATED prior to updating the stack instances in the specified accounts and Amazon Web Services Regions. If the StackSet update does not include changes to the template or parameters, CloudFormation updates the stack instances in the specified accounts and Amazon Web Services Regions, while leaving all other stack instances with their existing stack instance status.
- (string) –
Regions (list) –
The Amazon Web Services Regions in which to update associated stack instances. If you specify Regions, you must also specify accounts in which to update StackSet instances.

To update all the stack instances associated with this StackSet, do not specify the Accounts or Regions properties.

If the StackSet update includes changes to the template (that is, if the TemplateBody or TemplateURL properties are specified), or the Parameters property, CloudFormation marks all stack instances with a status of OUTDATED prior to updating the stack instances in the specified accounts and Regions. If the StackSet update does not include changes to the template or parameters, CloudFormation updates the stack instances in the specified accounts and Regions, while leaving all other stack instances with their existing stack instance status.
- (string) –
CallAs (string) –
[Service-managed permissions] Specifies whether you are acting as an account administrator in the organization’s management account or as a delegated administrator in a member account.

By default, SELF is specified. Use SELF for StackSets with self-managed permissions.
- If you are signed in to the management account, specify SELF.
- If you are signed in to a delegated administrator account, specify DELEGATED_ADMIN. Your Amazon Web Services account must be registered as a delegated administrator in the management account. For more information, see Register a delegated administrator in the CloudFormation User Guide.
ManagedExecution (dict) –
Describes whether CloudFormation performs non-conflicting operations concurrently and queues conflicting operations.
- Active (boolean) –
  
  When true, CloudFormation performs non-conflicting operations concurrently and queues conflicting operations. After conflicting operations finish, CloudFormation starts queued operations in request order.
  
  Note
  If there are already running or queued operations, CloudFormation queues all incoming operations even if they are non-conflicting.
  
  You can’t modify your StackSet’s execution configuration while there are running or queued operations for that StackSet.
  
  When false (default), StackSets performs one operation at a time in request order.
