docker couchdb data volume doesn't save to local filesystem

Docker newbie here...

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.

jubin@jubin-VirtualBox:~$ docker run -d -p 5984:5984 -v /home/jubin/data:/usr/local/var/lib/couchdb --name couchdb klaemo/couchdb
5e0d15b933d6344d3c6a28c26e1f2f59dba796697d47ff21b2c0971837c17e54
jubin@jubin-VirtualBox:~$ curl -X PUT http://172.17.0.2:5984/db
{"ok":true}
jubin@jubin-VirtualBox:~$ ls -ltr /home/jubin/data/
total 0

on inspect it seems to be correctly configured.
