Container Registry Auth Proxy

This is to avoid using docker login on every machine on LAN. By using this proxy you can provide unrestricted access to a private registry.

Usage:

1. Use docker login once to generate credentials.
2. Inspect $HOME/.docker/config.json, find auth for the registry:

   {
       "auths": {
           "registry.example.com": {
               "auth": "YOU NEED THIS STRING"
           }
       }
   }

3. Fill in the environment variables in docker-compose.yml:
   • NGINX_SERVER_NAME: host name of the proxy.
   • NGINX_AUTH_CREDENTIALS: the auth hash you've got during the previous step.
   • NGINX_PROXY_TO: URL of the private registry.
4. Bring up the proxy with docker-compose up and test it with docker pull $NGINX_SERVER_NAME/image:tag.
