title: docker couchdb data volume doesn't save to local filesystem
body: <p>Docker newbie here... </p>
  
  <p>I am trying to persist docker run couch db on my local filesystem but when I run the command I don't see the db files being saved. I tried researching but I seem to be doing everything right.</p>
  
  <pre><code>jubin@jubin-VirtualBox:~$ docker run -d -p 5984:5984 -v /home/jubin/data:/usr/local/var/lib/couchdb --name couchdb klaemo/couchdb

  jubin@jubin-VirtualBox:~$ curl -X PUT http://172.17.0.2:5984/db
  {"ok":true}
  jubin@jubin-VirtualBox:~$ ls -ltr /home/jubin/data/

  <p>on inspect it seems to be correctly configured. </p>
