I've been learning docker on an old 64bit IBM designed for XP using the a newish version of lubuntu.
There are still some things that make it unintuitive and in my view incomplete (eg. a command to copy/cut/paste/delete volumes).
A couple things I've found out: You should definitely use the Overlay FS driver as soon as possible; don't use DeviceMapper. Also, It can be convenient to use data volume containers but watch out for orphaned files in /var/lib/docker/tmp and always use -v.
