title: Mount single file from volume using docker-compose
body: <p>For local dev I need to mount a different config file in a Docker container. This is easy with the command line <code>-v $(pwd)/bla.yaml:/location/bla.yaml</code>. Is it possible to do this from a <code>volume</code> (created with <code>docker volume create bla</code>) in a <code>docker-compose</code> file?</p>
