title: Alternative to supervisord for docker
body: <p>Supervisord is really great tool even for docker environment. It helps a lot with stderr redirection and signals forwarding. But it has a couple of disadvantages:</p>
  
  <ol>
  <li>It doesn't support delayed startup. It could be useful to delay some agent startup until main app is initializing. Priority doesn't solve this issue.</li>
  <li>If some app enters FATAL state supervisord just logs it but continue to work. So you can't see it until look at logs of container. It could much more friendly if supervisord just stops because in that case you see the problem with <code>docker ps -a</code></li>
  </ol>
  
  <p>So what is the best alternative to supervisord?</p>
