  Get the IP of a droplet

       doex ip <droplet_id_or_name_or_tag>

  For example,

      doex ip my_app

  If you have a specific config file, `mix help doex.config` then add it as an environment variable

      DOEX_CONFIG=/tmp/my.doex doex ip my_app

  This is useful to SSH into your droplet, for example

      ssh root@`doex ip my_app`
