title: Run docker containers in detatched mode selectively
body: <p>I’m starting up a few containers with a docker-compose.yml file.  I would like all of them to start in detached mode <strong>except</strong> for one, which i would like to run attached.</p>
  
  <p>I can pass the detach flag on the command line with</p>
  
  <pre><code>docker-compose up -d
  </code></pre>
  
  <p>But I wonder if it’s possible to specify this in the yml file?</p>
