Container Registries

CodeFloe provides a proxy cache to common container registries, such as Docker Hub and GitHub Container Registry. This prevents rate-limiting during the use of CodeFloe CI.

The proxy cache is available at cr.codefloe.com.

Note

This proxy cache is only reachable from within CodeFloe, i.e. IP-limited to CodeFloe CI runners to prevent abuse. If you added your own runner/agent for Crow CI or Forgejo Actions, please contact us to enable access.

This only works for static agents, as we need a fixed IP to allow access. Autoscaled agents have dynamic IPs and cannot use the proxy cache.

Supported Registries

• docker.io (Docker Hub)
• ghcr.io (GitHub Container Registry)

Usage

docker.io (Docker Hub)

Instead of repo/image in your Dockerfile, use cr.codefloe.com/docker.io/<repo>/<image>:<tag>.

For official images like ubuntu and golang which don’t have a visible owner, specify the owner as library:

FROM cr.codefloe.com/docker.io/library/<image>:<tag>

ghcr.io (GitHub Container Registry)

Instead of ghcr.io/owner/image in your Dockerfile, use cr.codefloe.com/ghcr.io/owner/image.

FROM cr.codefloe.com/ghcr.io/<repo>/<image>:<tag>
