Conditionally create CodePipeline actions based on CloudFormation conditions

Question

Enable / disable sections of a CloudFormation for CodePipeline using Conditionals:

This creates a manual notification action once staging has been built and passed Runsc

Answer 1

You should be able to accomplish this by conditionally inserting the AWS::CodePipeline::Pipeline Resource's Action into the Actions list using the Fn::If Intrinsic Function referencing your Conditions element, returning the Action when the Condition is true and AWS::NoValue (which removes the property, in this case removing the item from the list) when it is not true:

- !If
  - IsProdCondition
  - InputArtifacts: []
    Name: !Join ["",[!Ref GitHubRepository, "-prd-approval"]]
    ActionTypeId:
      Category: Approval
      Owner: AWS
      Version: '1'
      Provider: Manual
    OutputArtifacts: []
    Configuration:
      NotificationArn: !GetAtt ["SNSApprovalNotification", "Outputs.SNSTopicArn"]
      ExternalEntityLink: OutputTestUrl
    RunOrder: 3
  - !Ref AWS::NoValue
