Move docker directory, Ubuntu/Debian

$ vi /etc/default/docker
DOCKER_OPTS="-g /somewhere/else/docker/"

1. Stop docker: service docker stop. Verify no docker process is running ps faux
2. Double check docker really isn’t running. Take a look at the current docker directory: ls /var/lib/docker/
3. Make a backup: tar -zcC /var/lib docker > /mnt/pd0/var_lib_docker-backup-$(date +%s).tar.gz
4. Move the /var/lib/docker directory to your new partition: mv /var/lib/docker /mnt/pd0/docker
5. Make a symlink: ln -s /mnt/pd0/docker /var/lib/docker
6. Take a peek at the directory structure to make sure it looks like it did before the mv: ls /var/lib/docker/ (note the trailing slash to resolve the symlink)
7. Start docker back up: service docker start
8. Restart your containers
