How do I set up GitLab Container Virtual Registry with Docker Hardened Images?

Use the Python client to create registry and upstreams for dhi.io, Docker Hub et al. Tweak CI to pull from your virtual URL. Auth once via GitLab.

Does GitLab Virtual Registry speed up CI/CD pipelines?

Hell yes—caches layers and manifests. First pull fetches upstream; rest served fast from GitLab infra. Hits 90%+ in mature setups.

Are Docker Hardened Images secure enough for production?

Minimal CVEs, SBOMs, SLSA. Great for workloads—but layer your own apps securely too. Not a silver bullet.
