title: Crontab won't restart Docker container
body: <p>I have a container that runs under a Root account which I can start using:</p>
  
  <pre><code>docker start containername
  </code></pre>
  
  <p>and I want crontab to start it, so as root I used</p>
  
  <pre><code>crontab -e
  </code></pre>
  
  <p>and set an entry like this:</p>
  
  <pre><code>* * * * * /usr/bin/docker start containername
  </code></pre>
  
  <p>but it won't work. I also tried</p>
  
  <pre><code>* * * * * root /usr/bin/docker start containername
  </code></pre>
  
  <p>with no luck.</p>
  
  <p>Anyone has a clue on how I can make this work?</p>
