Hi 👋

Unfortunately, there is no current support for Google Cloud Platform's Artifact Registry. However, the CLI supports GitHub Container Registry and Azure Container Registry.

We'd be happy to add support for GCP given the community's interested. Feel free to contribute a PR if you'd be interested.
Thanks!
