Use Google Cloud Artifact Registry as backend for Gitlab Registry

GCP Artifact Registry as backend for Gitlab Registry

I want to use Google Cloud Artifact Registry as backend for Gitlab Registry, this would allow me to simplify system administration and have a generic registry.

I tried to configure gitlab as an auth endpoint for an external registry but it does not seem to work. My image get uploaded on the gitlab instance filesystem and I can’t see it in the Container Registry tab.

I’m using gitlab omnibus 15.0.

Does Gitlab support using artifact registry as backend ?
