If you want to run services in docker containers with Docker Toolbox (e.g. a mysql db), and you want the db stored on the Mac host, then you have to worry about 2 layers of folder mounts (one from host -&gt; vm, one from vm -&gt; container), another 2 layers of port forwarding (same as above), to make it &#x27;feel&#x27; like your&#x27;re running mysql locally.<p>With the beta, all of that is taken care for you with a couple of settings, and it&#x27;s just much simpler to get up and running.
