[Cialug] Docker Volumes

[Andy Denner]

For more control over system wide volumes for docker, my understanding 
is that you could mount a disk (or simlink) for /var/lib/docker/volume

Another option would be to look into using a volume driver. From there 
you could use plugins like sshfs, cifs, or NFS.

Finally you could just set your volume in compose to a local folder 
instead of letting docker volumes handle it... something like

/var/lib/docker will also contain all of the container layers and other 
cruft of docker as well.
