Docker private registry with mirror

Question

I created two Docker containers. The first one provides a private Docker registry and the second one is a mirror of the official Docker registry:

docker run          


        

Answer 1

Repository names are intended to be global, that is the repository redis always refers to the official Redis image from the Docker Hub. If you want to use a private registry, you prefix the repository name with the name of the registry e.g. localhost.localdomain:5000/myimage:mytag.

So when you pull or push, it will automatically go to the relevant registry. The mirror should be easy to set up, you just pass the URL to the daemon with the --registry-mirror= argument.

This isn't perfect for enterprise users, hence this (closed) Docker issue.
