Unstable still has a docker.io, though testing does not (update: it does now; the docker package also recently got updated to a more current version). Docker was not included in the last stable release. I have not used docker in quite some time. I use systemd-nspawn containers which are much easier to build and maintain. So, it may make sense to either mark the docker module in propellor as unmaintained, or find someone else to maintain it. """]]
