Bases: Action

CodePipeline action to create/update Stack Instances of a StackSet.

After the initial creation of a stack set, you can add new stack instances by using CloudFormationStackInstances. Template parameter values can be overridden at the stack instance level during create or update stack set instance operations.

Each stack set has one template and set of template parameters. When you update the template or template parameters, you update them for the entire set. Then all instance statuses are set to OUTDATED until the changes are deployed to that instance.




# pipeline: codepipeline.Pipeline
# source_output: codepipeline.Artifact

        # First, update the StackSet itself with the newest template

            # Change this to 'StackSetDeploymentModel.organizations()' if you want to deploy to OUs
            # This deploys to a set of accounts
            stack_instances=codepipeline_actions.StackInstances.in_accounts(["111111111111"], ["us-east-1", "eu-west-1"])

        # Afterwards, update/create additional instances in other accounts
            stack_instances=codepipeline_actions.StackInstances.in_accounts(["222222222222", "333333333333"], ["us-east-1", "eu-west-1"])
  • stack_instances (StackInstances) – Specify where to create or update Stack Instances. You can specify either AWS Accounts Ids or AWS Organizations Organizational Units.

  • stack_set_name (str) – The name of the StackSet we are adding instances to.

  • parameter_overrides (Optional[StackSetParameters]) – Parameter values that only apply to the current Stack Instances. These parameters are shared between all instances added by this action. Default: - no parameters will be overridden

  • role (Optional[IRole]) – The Role in which context’s this Action will be executing in. The Pipeline’s Role will assume this Role (the required permissions for that will be granted automatically) right before executing this Action. This Action will be passed into your IAction.bind method in the ActionBindOptions.role property. Default: a new Role will be generated

  • failure_tolerance_percentage (Union[int, float, None]) – 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 subsequent Regions. When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number. Default: 0%

  • max_account_concurrency_percentage (Union[int, float, None]) – 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. If rounding down would result in zero, AWS CloudFormation sets the number as one instead. Although you use this setting to specify the maximum, for large deployments the actual number of accounts acted upon concurrently may be lower due to service throttling. Default: 1%

  • stack_set_region (Optional[str]) – The AWS Region the StackSet is in. Note that a cross-region Pipeline requires replication buckets to function correctly. You can provide their names with the PipelineProps.crossRegionReplicationBuckets property. If you don’t, the CodePipeline Construct will create new Stacks in your CDK app containing those buckets, that you will need to cdk deploy before deploying the main, Pipeline-containing Stack. Default: - same region as the Pipeline

  • action_name (str) – The physical, human-readable name of the Action. Note that Action names must be unique within a single Stage.

  • run_order (Union[int, float, None]) – The runOrder property for this Action. RunOrder determines the relative order in which multiple Actions in the same Stage execute. Default: 1

  • variables_namespace (Optional[str]) – The name of the namespace to use for variables emitted by this action. Default: - a name will be generated, based on the stage and action names, if any of the action’s variables were referenced - otherwise, no namespace will be set


bind(scope, stage, *, bucket, role)

The callback invoked when this Action is added to a Pipeline.

Return type:


on_state_change(name, target=None, *, enabled=None, event_bus=None, schedule=None, targets=None, cross_stack_scope=None, description=None, event_pattern=None, rule_name=None)

Creates an Event that will be triggered whenever the state of this Action changes.

  • name (str) –

  • target (Optional[IRuleTarget]) –

  • enabled (Optional[bool]) – Indicates whether the rule is enabled. Default: true

  • event_bus (Optional[IEventBus]) – The event bus to associate with this rule. Default: - The default event bus.

  • schedule (Optional[Schedule]) – The schedule or rate (frequency) that determines when EventBridge runs the rule. You must specify this property, the eventPattern property, or both. For more information, see Schedule Expression Syntax for Rules in the Amazon EventBridge User Guide. Default: - None.

  • targets (Optional[Sequence[IRuleTarget]]) – Targets to invoke when this rule matches an event. Input will be the full matched event. If you wish to specify custom target input, use addTarget(target[, inputOptions]). Default: - No targets.

  • cross_stack_scope (Optional[Construct]) – The scope to use if the source of the rule and its target are in different Stacks (but in the same account & region). This helps dealing with cycles that often arise in these situations. Default: - none (the main scope will be used, even for cross-stack Events)

  • description (Optional[str]) – A description of the rule’s purpose. Default: - No description

  • event_pattern (Union[EventPattern, Dict[str, Any], None]) – Additional restrictions for the event to route to the specified target. The method that generates the rule probably imposes some type of event filtering. The filtering implied by what you pass here is added on top of that filtering. Default: - No additional filtering based on an event pattern.

  • rule_name (Optional[str]) – A name for the rule. Default: AWS CloudFormation generates a unique physical ID.

Return type:




The simple properties of the Action, like its Owner, name, etc.

Note that this accessor will be called before the bind callback.
