>There is controversy about Docker not running on FreeBSD but I believe (like many others) that FreeBSD has a more powerful tool. Jails are older and more mature - and by far - than any containerization solution on Linux.

If FreeBSD jails and Solaris zones were equivalent to Linux containers, we'd have seen them take over the backend already. We haven't. They're really useful, they provided a degree of safety and peace of mind for multi-tenancy but they're not granular enough for what's done with $CONTAINER_RUNTIME these days.

Jérôme Petazzoni has an old talk where he touches upon container primitives and compared them to jails : https://www.youtube.com/watch?v=sK5i-N34im8
