title: Empty directory when mounting volume using windows for docker
body: <p>I am attempting to mount a volume from C:/Users into a container running on a docker-machine using the hyperv driver on docker for windows (win 10 pro).  I am a using the lastest docker (1.13.1) and the same on the hyper vm machine. I have tried switching to using a local account, shared the drive in the docker settings menu and ive pretty much tried everything i could find on google.</p>
  
  <p>Running the test volume run command in the settings menu works for me. At this point in time I presume hyperv does not support mounting volumes from the host however i cant find anywhere that explicitly says that volumes mounting will not work in hyperv.</p>
  
  <p>This is my docker-compose config:</p>
  
  <pre><code>networks: {}
  services:
    app:
      build:
        context: C:\users\deep\projects\chat\app
      command: sleep 3600
      image: app
      links:
      - rethinkdb
      - redis
      ports:
      - 4005:4005
      - 4007:4007
      volumes:
      - /c/users/deep/projects/chat/app:/usr/src/app:rw
    redis:
      image: redis
    rethinkdb:
      image: rethinkdb:2.3.5
  version: '2.0'
  volumes: {}
  </code></pre>
  
  <p>In my Dockerfile i can see copy files into the container to <code>usr/src/app</code>. When i <code>up</code> the services with the volume specified in the compose file the directory is emptied, however i omit this volume mount i can see my files that i copied into the container from the dockerfile.</p>
  
  <p>Running verbose when starting my services i can see a volumes path specified as such  <code>'Binds': [u'/c/users/deep/projects/chat/app:/usr/src/app:rw']</code>.  However, when i inspect the container using <code>docker-compose inspect app</code> i see volumes set to null <code>"Volumes": null</code>.</p>
  
  <p>I presume at this point that mounting volumes into a container running inside a hyperv VM is not supported? Can someone confirm so that I can RIP :)</p>
