      With the docker client installed on your host machine, you can now use Docker as
      you'd expect, by simply telling it where to find the docker daemon:

        $ export DOCKER_HOST='tcp://#{$vm_ip}:2375'
        $ docker ps

      Additionally, many GG tools/docs expect you to add an entry to /etc/hosts for
      this VM. Add this line to your /etc/hosts file:

        #{$vm_ip} docker.dev
    MSG
  end
