class aws_cdk.aws_codepipeline_actions.CodeCommitSourceAction(*, output, repository, branch=None, code_build_clone_output=None, custom_event_rule=None, event_role=None, trigger=None, role=None, action_name, run_order=None, variables_namespace=None)

Bases: Action

CodePipeline Source that is provided by an AWS CodeCommit repository.

If the CodeCommit repository is in a different account, you must use CodeCommitTrigger.EVENTS to trigger the pipeline.

(That is because the Pipeline structure normally only has a RepositoryName field, and that is not enough for the pipeline to locate the repository’s source account. However, if the pipeline is triggered via an EventBridge event, the event itself has the full repository ARN in there, allowing the pipeline to locate the repository).

  • output (Artifact) –

  • repository (IRepository) – The CodeCommit repository.

  • branch (Optional[str]) – Default: ‘master’

  • code_build_clone_output (Optional[bool]) – Whether the output should be the contents of the repository (which is the default), or a link that allows CodeBuild to clone the repository before building. Note: if this option is true, then only CodeBuild actions can use the resulting output. Default: false

  • custom_event_rule (Optional[ICustomEventRule]) – You can pass a customEventRule to set up a custom event rule for the CodeCommit source action. You must provide the eventPattern and target properties in the customEventRule object. Check which eventPattern to use: Default: Event rule which is triggered by CodeCommit repository on commit

  • event_role (Optional[IRole]) – Role to be used by on commit event rule. Used only when trigger value is CodeCommitTrigger.EVENTS. Default: a new role will be created.

  • trigger (Optional[CodeCommitTrigger]) – How should CodePipeline detect source changes for this Action. Default: CodeCommitTrigger.EVENTS

  • 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

  • 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.


The variables emitted by this action.
