I use it for some projects because it makes moving between servers really easy. If you use docker-compose and put volumes inside one directory, it involves only a few simple steps: install docker on a new machine, rsync the directory there, ssh in, and run docker-compose up. That's it. With a fast network (or small amounts of data) it can be done in 2-5 minutes. Doing it without docker requires you to maintain either 1k+ lines of Ansible playbooks (and test it regularly!), or spending a day configuring everything manually. Full backups are also trivial, if you can afford some downtime: docker-compose down && restic … && docker-compose up. If you cannot afford downtime, the docker volumes go onto a ZFS or LVM partition.
