title: How to restart Node on a docker container without restarting the whole container?
body: <p>I have a container ==> <code>FROM node:5</code>
  Node should restart after each change in the code. </p>
  
  <p>But there is no way for me restart the Node server without restarting the whole docker container.</p>
  
  <p>I have many <code>npm install</code> on dockerfile that runs each time I restart the container, and it's annoying to wait for all of them after each change in the code.</p>
  
  <p>I'm already using shared folder to have the latest code in my container.</p>
