title: mounting volume into docker container
body: <p>How would i mount a path from host into the container without overriding the already existing contains at the same mounted path.</p>
  <p>Confused? let me give an example:</p>
  <p>Built a docker image with WORKDIR as <em><strong>/app</strong></em> and baked it with file <em><strong>/app/config1</strong></em>. Now, i will be adding few config files in runtime at hosts ~/ and want these in the container at same <em><strong>/app</strong></em> path</p>
  <p>When i do <code>docker run -v ~/:/app example</code>
  It seems to be deleting the baked <em><strong>config1</strong></em> file</p>
  <p>Any pointers on how to solve this use-case? Ofcourse, other then mounting at different path.</p>
  <p>TIA!</p>
