If
google.Keychainis used withNewMultiKeychain, it will be selected to provide credentials to pull or push images for images in GCR/AR. If, in this case, Application Default Credentials aren't configured andgcloudis not available or configured to provide credentials, the keychain will fail, even if the image is otherwise publicly available.With this change, if the env credential lookup and
gcloudcredential lookup both fail, instead of returning an error,google.Keychainwill fallback to returnauthn.Anonymousinstead. In this case,NewMultiKeychainwill fall through each option in turn, until finally usingauthn.Anonymousif none match and provide credentials.
