That's not good and it sounds like a > discriminatory attitude. I think you're mis-representing the position of a lot of people here; please don't do that. The fast-moving Docker.com tech has been moving towards a standards-based "Open Container" https://opencontainers.org/ definition, and many people have worked across the standard, the implementation, kernel, & tooling, now in ports on FreeBSD, to make this possible. Just a few examples: - https://github.com/samuelkarp/runj/ - https://github.com/dfr/ocijail/ - https://medium.com/@dfr/oci-containers-for-freebsd-512a6df2bc85 It would be great to get your feedback on one of these and see what you tried, and where it breaks with your expectations. While it may be possible to run many linux containers with this tooling, systemd and other linux-specific things could be present in any container you pull, from systemd, to filesystem requirements, and expecting all of these to work seamlessly is unrealistic. If you want the full Linux-compatible Docker experience, then, yes, use Linux, either in a VM, or directly. I don't think there are many FreeBSD people who use only 1 OS, we are by and large pragmatic people. It's ok to use different tools in different situations. A+ Dave
