title: side effect of --rm: when exit a container build with docker run --rm -v /myvol, also the volume is removed
body: <p>I do,</p>
  
  <pre><code>[eric@almond volume]$ docker run  --rm --name vol -v /myvol2 -ti my/fedora-volume bash
  [root@5a750a63db1d /]# exit
  exit
  </code></pre>
  
  <p>With <code>docker volume ls</code> I see that the volume is gone.</p>
  
  <p>Now I do without --rm,</p>
  
  <pre><code>[eric@almond volume]$ docker run  --name vol -v /myvol2 -ti my/fedora-volume bash
  [root@5a750a63db1d /]# exit
  exit
  [eric@almond ch44]$ docker rm vol
  vol
  </code></pre>
  
  <p>Now I see with <code>docker volume ls</code> that the volume is still there.</p>
  
  <p>So has <code>docker run --rm</code> the side effect that also the volume is removed?</p>
