Summary
The user is transitioning from GitHub Container Registry to Google Artifact Registry (GAR) and is experiencing issues with logging in from an Earthfile. They are looking for the correct authentication method for GAR, as the standard docker login does not work. Despite trying to authenticate with the Google Cloud SDK, they are unable to push images to GAR. The user has encountered errors when passing JSON credentials directly, so they encoded the credentials in base64 and shared a code snippet of their method. They express a need for professional guidance and plan to discuss the issue in a meeting later that day.
