What's the difference between them and which one should I use = to run docker images on FreeBSD host? I believe at this point in time, all you can do is have a Linux machine = somewhere (for example, in a local Bhyve VM), and use the Docker command = line client from FreeBSD to manage it.

It looks abandoned, unfortunately. And looking at the entire container = infrastructure, reviving it would require a significant effort. For = example, it most real-life usage scenarios, you want to be able to = manipulate IPFW/PF entries to forward ports from a host interface into a = container, which would require special plugins for Docker, or a = compatibility shim that allows Docker to use iptables APIs/ABIs. Going even further, pretty much everything in the ecosystem (k8s, etc.) = assumes it's running on top of a Linux kernel including a number of = management APIs that are not (completely) emulated on FreeBSD. While I would love to see proper Docker support in FreeBSD, I=E2=80=99m = not sure its even the right thing to aim for. In Docker production = environments, people generally try to pare down the host OS to the = absolute minimum, and at that point, what benefit would you derive from = FreeBSD as a host? Similarly, why would you want to run FreeBSD-ABI containers, = specifically? One of the benefits of the container ecosystem is that = there are many ready-made images you can build on. Having to re-invent = all of this seems of little benefit to me. Just my 2 cents, Stefan --=20 Stefan Bethke <stb@lassitu.de> Fon +49 151 14070811
