Question

A development team creates a new AWS CodePipeline using the console. During the source stage, artifacts produced by CodeCommit need to be passed to a CodeBuild stage. The team wants to understand how output artifacts are stored and moved between stages so they can grant the correct permissions to a custom CodeBuild service role. Where does CodePipeline store the artifacts that are passed between stages?

Accepted Answer

In an Amazon S3 artifact bucket that CodePipeline creates or uses per Region, encrypted at rest, with each stage reading input and writing output artifacts to this bucket

Answer

In an Amazon EFS file system mounted to each stage's compute environment for shared read/write access

Answer

In an Amazon DynamoDB table where each artifact is stored as a base64-encoded item passed to the next action

Answer

In the CodeCommit repository itself, with each downstream stage pulling directly from the repo branch
