imagePullCredentialsTypeOverride

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's service principal.

SERVICE_ROLE

Specifies that CodeBuild uses your build project's service role.

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