I wrote some thoughts about this at: https://github.com/alexpdp7/alexpdp7/blob/master/programming/python/creating_nice_python_cli_tools.md

It allows me to expand disk size fairly easily when needed. So i use 8gb as initial size instead of 30gb. Offcourse overlay2 works fine on it. You can handle snapshots/backups via ZFS itself! The volume is just another object on your zfs pool, so whatever you use for managing it can work with volumes as well. Eg I use Sanoid for my snapshot management (and included syncoid for remote replication) Now install docker, then portainer.
