This year I have been spending much of my time porting the github.com/containers stack to #FreeBSD. This is now available to install on FreeBSD-13.1 and later - just run 'pkg install podman-suite' to get all the pieces.
There are still a few rough edges but most of the core functionality is there including networking, image management, containers, pods and more. Take a look at #podman if you've been missing a docker-like #container engine on #FreeBSD.
@dfr are there docs for usage on FreeBSD?
@karinjiri @fuzzykb Buildah is a lot more powerful than traditional Containerfile builds - I use it to build small freebsd images here: https://github.com/dfr/freebsd-images
