FreeBSD is quietly prevalent in commercial and government settings. Juniper and NetApp are just two renowned examples. There have been and are many others.

Separate from any of those, a good chunk of America's more sensitive production database clusters, other workloads, and some network applications are scheduled by Nomad or Kubernetes running directly on a kernel that is not Linux.

The most popular kernel is not necessarily appropriate for all use cases or types of environments where high-value targets reside.

Directly downstream of FreeBSD, HardenedBSD achieved its long history of invulnerability to what were exploitable vulnerabilities in upstream through its advancements in the operating system layer.

Do you mean Kubernetes on Windows?

Obviously not.

Nomad and Kubernetes orchestrate Linux containers using features of the Linux kernel (except where Windows kernel support has also been added).

Maybe you're thinking of jails? I'm not sure if there's any mainstream/popular distributed orchestration systems for those.

Okay... can you name a specific thing? I'm confused. Nomad and Kubernetes both support Windows workers well. Kubernetes, afaik, doesn't support something like OpenBSD in a common flavor like RKE.

		Kubernetes' core pieces of userspace software, not with any implied support from the Kubernetes project, also run on illumos, FreeBSD (and HardenedBSD), and OpenBSD. In some advanced settings where tolerances for potential impacts resulting from exploited software vulnerabilities are intensely low, Kubernetes (userspace software) on HardenedBSD is choice for mission. Like with the other two systems, those running Kubernetes userspace on them are self-sufficient and are not among the audience of external more general Kubernetes distro support channels. If you happen to like RKE, check out https://Talos.dev which is the best Kubernetes on Linux distro (for most Kubernetes on Linux use cases). _ @nijave Nomad and Kubernetes schedule containers, which are rarely not Linux containers, yeah. Both can schedule processes in FreeBSD's BSD Jails. If someone wants to start an open Kubernetes on FreeBSD/HardenedBSD project I would encourage that. Personally I would like to see an open Kubernetes on illumos project. As far as I know where Kubernetes on HardenedBSD runs is not interested in open projects.
