In this post we’ve learned how to proxy PyPI and make it cached in our local repo, but for this time I want to share similar thing but it’s for docker image. Here we go!

  • Make docker group and docker proxy

We can see the configurations below :

Explanation :

  1. Name of proxy repository
  2. Allow anonymous user for pulling the image
  3. Remote registry. https://registry-1.docker.io is docker hub remote storage URL.
  4. Use docker hub as docker index

Explanation :

  1. Name of group repository
  2. 5000 is port number for pulling the image through nexus registry
  3. Allow anonymous user for pulling the image.
  4. Set docker-proxy ( proxied docker registry we’ve created before ) to be a member of this group repo
  • Tell docker to consider the image registry we’ve created as registry mirrors to cache the image and as insecure registry, so there’s no need to verify TLS ( not recommended for production env ) by creating new file called daemon.json in /etc/docker directory

Restart docker service afterwards. Then verify by executing docker info

  • Try to pull an image

And it works like a charm !
