title: How to pass arguments to a docker container without specifying a CMD
body: <p>Currently if I run a container I <em>must</em> speicfy a new <code>CMD</code> in order to pass args.</p>
  <p>I.e. the format is <code>docker run image [CMD] [ARGS]</code></p>
  <p>Is there any way to pass args to the <code>CMD</code> at the end of the <code>Dockerfile</code> without specifying a new <code>CMD</code> when running the container.</p>
