title: mysql with Exited(1) from docker
body: <p>Start learning docker and try to setup a mysql container.  But it dies immediately with Exited(1).  </p>
  
  <p>Following is the command used</p>
  
  <pre><code>docker run mysql -e MYSQL_ROOT_PASSWORD=password1
  </code></pre>
  
  <p>Looking at docker ps, it does not show any running docker container</p>
  
  <p>with docker ps -a  returns the following :</p>
  
  <pre><code>CONTAINER ID    IMAGE   COMMAND                     CREATED             STATUS                          PORTS    NAMES
  e681f56c52e2    mysql   "/entrypoint.sh -e MY"      3 seconds ago       Exited(1) 3 seconds ago                  lonely_rosalind
  </code></pre>
  
  <p>Nothing shows up for docker logs lonley_rosalind either</p>
  
  <p>Any idea how to determine why if failed ?  </p>
  
  <p>I am running </p>
