People comparing Docker and Jails don't really understand that Docker is 99% about packaging and composing software. From that perspective Jails are nothing like Docker containers. No versioning, no standard, no registry, no compose, no healthchcks, no tree of containers, etc. etc. etc.

If you want to compare Jails to something on Linux then I think LXD is probably much closer to what Jails are.
