imagePullCredentialsType

The type of credentials CodeBuild uses to pull images in your build. There are two valid values:

• CODEBUILD specifies that CodeBuild uses its own credentials. This requires that you modify your ECR repository policy to trust CodeBuild service principal.

• SERVICE_ROLE specifies that CodeBuild uses your build project's service role.

When you use a cross-account or private registry image, you must use SERVICE_ROLE credentials. When you use an CodeBuild curated image, you must use CODEBUILD credentials.
