Troubleshoot Artifact Registry
Resolve Docker authentication, repository, and image-selection problems.
Docker login fails
Use the registry host from the Console and the displayed Docker username. The password is a personal access token, not an account sign-in password. Check whether the token is expired or revoked and ensure you are signing in to the correct registry.
Login succeeds but push or pull is denied
Verify the full project registry address and your current project permissions. A token cannot access a repository merely because you know its name. Ask a project administrator to review access when necessary.
An image is missing from the Console
Confirm that the push completed to the same project registry address. Refresh the repository list, select the repository, and use pagination to inspect older images. Images without tags can still appear by digest.
The deployed application uses an older image
Container Engine selects Artifact Registry images by digest. Publishing a new tag does not mutate the running deployment. Follow the image-update workflow supported by that container and redeploy when required.
If a failure persists, share the repository path, digest, timestamp, and error text with support. Exclude access tokens and Docker credential files.
