title: docker (running in virtual box) expose port on host machine
body: <p>I'm running docker in <strong>virtual box</strong> (docker machine) on a <strong>MAC server</strong>. I have some running containers that expose certain ports to the host machine, so I can access them via <strong>URL of the virtual machine + exposed port</strong>. But I'm <strong>not</strong> able to reach the exposed services f<strong>rom outside</strong> the host system, as the docker containers are sandboxed in their own virtual network I guess.</p>
  
  <p>Is it possible to also expose the port on the host machine so people from outside can reach the web services running in docker inside my virtual machine?</p>
