title: docker-compose up for only certain containers
body: <p>I have a <code>docker-compose.yml</code> which contain several containers.  Three of them are for my app (client, server and database) and the rest are for various dev tools (e.g. psql, npm, manage.py, etc).  When I do <code>docker-compose up</code> all of them are started, but I only want the three main ones to start.  Because of the links I've specified, I can start just those three with <code>docker-compose up client</code> but then the output is only from that one container. So, is there a way to do one of the following:</p>
  
  <ol>
  <li>Tell docker-compose which containers should by started by <code>docker-compose up</code></li>
  <li>Get output from all linked containers from <code>docker-compose up client</code></li>
  </ol>
