Docker Registry Proxy is a caching proxy for Docker that centrally manages multiple registries and their authentication.

  • Other
Docker Registry Proxy is a caching proxy for Docker that centrally manages multiple registries and their authentication. It caches large blob/layer requests to save bandwidth and pull time, and can optionally cache manifest pulls to help avoid Docker Hub rate limits. It's a useful homelab tool for anyone who wants a fast, reliable pull mirror in front of any container registry.

Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

Common questions

How can I use this proxy to reduce Docker Hub pull rate limiting?

Set ENABLE_MANIFEST_CACHE=true so the proxy caches manifest requests. You can then fine-tune the related environment variables to your needs.

Can the proxy centrally manage authentication for multiple registries?

Yes, it allows centralised management of multiple registries and their authentication. It can also centrally inject authentication.

Is there an option to disable IPv6?

Yes, set DISABLE_IPV6=true to disable IPv6.
