update_stack_set#

CloudFormation.Client.update_stack_set(**kwargs)#

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

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

Parameters:

StackSetName (string) –
[REQUIRED]

The name or unique ID of the stack set 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. For more information, see Template Anatomy in the CloudFormation User Guide.

Conditional: You must specify only one of the following parameters: TemplateBody or TemplateURL—or set UsePreviousTemplate to true.
TemplateURL (string) –
The location of the file that contains the template body. The URL must point to a template (maximum size: 460,800 bytes) that is located in an Amazon S3 bucket or a Systems Manager document. For more information, see Template Anatomy in the CloudFormation User Guide.

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 stack set 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 stack set 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 SSM parameter key. This field is returned only for SSM parameter types in the template.
Capabilities (list) –
In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for CloudFormation to update the stack set 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 Identity and Access Management (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 stack set template references one or more macros, you must update the stack set directly from the processed template, without first reviewing the resulting changes in a change set. To update the stack set directly, you must acknowledge this capability. For more information, see Using CloudFormation Macros to Perform Custom Processing on Templates.
Warning
Stack sets 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 stack set with service-managed permissions, if you reference a macro in your template the stack set operation will fail.
- (string) –
Tags (list) –
The key-value pairs to associate with this stack set 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 stack set. 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 stack set, even tags you’ve specified before (for example, when creating the stack set or during a previous update of the stack set.). Any tags that you don’t include in the updated list of tags are removed from the stack set, 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 stack set from the list of tags you specify, 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.
- (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]
    
    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 (Amazon Web Services) have the reserved prefix: aws:.
  - Value (string) – [REQUIRED]
    
    Required. A string containing 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 stack set 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.
  
  Note
  RegionOrder isn’t followed if AutoDeployment is enabled.
  - (string) –
- FailureToleranceCount (integer) –
  
  The number of accounts, per Region, for which this operation can fail 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.
  
  Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage (but not both).
  
  By default, 0 is specified.
- FailureTolerancePercentage (integer) –
  
  The percentage of accounts, per Region, for which this stack operation can fail 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.
  
  Conditional: You must 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.
  
  Conditional: You must 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.
  
  Conditional: You must 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 MaxConcurrentCount +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 stack set operations to run at the concurrency level set by the MaxConcurrentCount value, or MaxConcurrentPercentage, regardless of the number of failures.
AdministrationRoleARN (string) –
The Amazon Resource Name (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 Granting Permissions for Stack Set Operations in the CloudFormation User Guide.

If you specified a customized administrator role when you created the stack set, you must specify a customized administrator role, even if it is the same customized administrator role used with this stack set previously.
ExecutionRoleName (string) –
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 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.

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 stack set, so long as you have permissions to perform operations on the stack set.
DeploymentTargets (dict) –
[Service-managed permissions] The Organizations accounts in which to update associated stack instances.

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

If the stack set 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 stack set 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 names of one or more Amazon Web Services accounts for which you want to deploy stack set updates.
  - (string) –
- AccountsUrl (string) –
  
  Returns the value of the AccountsUrl property.
- OrganizationalUnitIds (list) –
  
  The organization root ID or organizational unit (OU) IDs to which StackSets deploys.
  - (string) –
- AccountFilterType (string) –
  
  Limit deployment targets to individual accounts or include additional accounts with provided OUs.
  
  The following is a list of possible values for the AccountFilterType operation.
  - INTERSECTION: StackSets deploys to the accounts specified in Accounts parameter.
  - DIFFERENCE: StackSets excludes the accounts specified in Accounts parameter. This enables user to avoid certain accounts within an OU such as suspended accounts.
  - UNION: StackSets includes additional accounts deployment targets. This is the default value if AccountFilterType is not provided. This enables user to update an entire OU and individual accounts from a different OU in one request, which used to be two separate requests.
  - NONE: Deploys to all the accounts in specified organizational units (OU).
PermissionModel (string) –
Describes how the IAM roles required for stack set 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 Stack Set Permissions.
- With service-managed permissions, StackSets automatically creates the IAM roles required to deploy to accounts managed by Organizations. For more information, see Grant Service-Managed Stack Set Permissions.
AutoDeployment (dict) –
[Service-managed permissions] Describes whether StackSets automatically deploys to Organizations accounts that are added to a target organization or organizational unit (OU).

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 stack set operation.

The operation ID also functions as an idempotency token, to ensure that 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 CloudFormation successfully received them.

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

Repeating this stack set 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 stack set instances.

To update all the stack instances associated with this stack set, don’t 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, 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 stack set 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 stack set instances.

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, 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, 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 stack sets 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 StackSets performs non-conflicting operations concurrently and queues conflicting operations.
- Active (boolean) –
  
  When true, StackSets performs non-conflicting operations concurrently and queues conflicting operations. After conflicting operations finish, StackSets starts queued operations in request order.
  
  Note
  If there are already running or queued operations, StackSets queues all incoming operations even if they are non-conflicting.
  
  You can’t modify your stack set’s execution configuration while there are running or queued operations for that stack set.
  
  When false (default), StackSets performs one operation at a time in request order.

Return type:
