Add local registry mirror to docker daemon on systemd ubuntu (after 15.04)

After docker installation, follow this steps

  • Create directory /etc/systemd/system/docker.service.d if not exist
  • Create mirror.conf file inside that directory. The name "mirror" can be changed to anything.
  • In the file, add this lines
ExecStart=/usr/bin/docker daemon -H fd:// --registry-mirror=http://registry-host:registry-port
  • registry-host is hostname/ip of your local registry mirror
  • registry-port is port of your local registry mirror
  • Flush the change with $ sudo systemctl daemon-reload
  • Restart docker with $ sudo systemctl restart docker
  • Check if the change is successfully applied with $ systemctl status docker,  your config should appear somewhere in the command output.
Tested on Docker 1.11, Ubuntu 15.10 & 16.04

If you want more explanations about these commands, please refer to follow links. Thank you for all of them for providing me a direction to solve the issue and also come up with this post.
