Authenticaton warning when using application default credentials

This issue has been tracked since 2022-11-19.


I'm running a self-hosted GitHub Actions runner on a GKE cluster. Permissions are handled through application default credentials (Workload Identity) and my workflow works correctly (no authorization errors). Unfortunately setup-gcloud still spits out a warning: **Warning**: No authentication found for gcloud, authenticate with google-github-actions/auth.


Expected behavior

I did not expect a warning, considering that the workflow works correctly and interacts with multiple GCP services for which authorization is definitely required.

Observed behavior

An authentication warning is displayed in the workflow logs and as an annotation under the job overview.

Hi @jorob16

This is correct and this is just a warning. We emit a warning when there are no credentials set by the auth action. This is just a warning and can be safely ignored for your use case.

Here's what "just a warning" looks like for anyone hoping to use setup-gcloud in CI - e.g. to install_components: cloud-datastore-emulator for testing:


It would be nice if there were a way to disable this message because it drowns out actual actionable information by desensitizing anyone from paying attention to the warning output.
