title: Mount data volume to docker with read&write permission
body: <p>I want to mount a host data volume to docker. But the container should have read and write permission to it, meantime, <strong>any changes on the data volumes should not affect the data in host.</strong></p>
  
  <p>I can image a solution that mount several data volumes to single folder, one is read only another is read and write. But only this second '-v' works in my command,</p>
  
  <pre><code>docker run -ti --name build_cent1 -v /codebase/:/code:ro -v /temp:/code:rw centos6:1.0 bash
  </code></pre>
