Explore the pipeline CloudFormation action

At NovaTech, your team wants to gate infrastructure changes in its pipeline. Use the pipeline CloudFormation action explorer to see how CloudFormation integrates into CodePipeline as a deploy stage.

The explorer shows a 4-stage pipeline (Source, Build, Deploy Infra, Deploy App) and lets you explore the CloudFormation action modes: CREATEUPDATE, CHANGESETREPLACE, and CHANGESET_EXECUTE. See how the gated change-set workflow adds a manual approval step between creating and executing a change set.

Question: Your team wants to review infrastructure changes before they apply. Which combination of CloudFormation action modes in CodePipeline enables this gated workflow?
