Registry

CERN Registry

The official production registry is hosted by gitlab.cern.ch.

This page documents an experimental registry fully OCI compliant, available at registry.cern.ch

The official Harbor documentation can be found here.

DockerHub Cache (under testing)

A proxy cache is available to hub.docker.com, which should offer a lower latency and higher bandwidth option for workloads running inside CERN. To use it, prefix the image with registry.cern.ch/docker.io, so:

docker pull myrepo/myimage:mytag becomes registry.cern.ch/docker.io/myrepo/myimage:mytag

A special case are the default images, where you need to prefix with library, so:

docker pull ubuntu:20.04 becomes docker pull registry.cern.ch/docker.io/library/ubuntu:20.04

Repositories

By default newly created repositories have a limited quota of 5GB. If you need more space please open a Service Desk ticket.
