Valid settings for the PollForSourceChanges parameter - AWS CodePipeline

Valid settings for the PollForSourceChanges parameter

The PollForSourceChanges parameter default is determined by the method used to create the pipeline, as described in the following table. In many cases, the PollForSourceChanges parameter defaults to true and must be disabled.

When the PollForSourceChanges parameter defaults to true, you should do the following:

  • Add the PollForSourceChanges parameter to the JSON file or AWS CloudFormation template.

  • Create change detection resources (CloudWatch Events rule, as applicable).

  • Set the PollForSourceChanges parameter to false.

    Note

    If you create a CloudWatch Events rule or webhook, you must set the parameter to false to avoid triggering the pipeline more than once.

    The PollForSourceChanges parameter is not used for Amazon ECR source actions.
