title: How can I use VOLUME in a Dockerfile to persist individual files in a directory?
body: <p>This application I'm trying to Dockerize has configuration files in the root of the install dir. If I use <code>VOLUME</code> to mount the install dir on the host, I'll end up with the application on the host, too. I only want to store the configuration files on the host.</p>
  
  <p>Should I use hard links in the container and use VOLUME to mount the dir that has the hardlinks? Do hard links even work in a container?</p>
