Rocky Linux is not a replacement, it’s an alternative. CentOS Stream is doing great so far.
We mostly test on RHEL and CetntOS Stream with bunch of our community using various alternatives including Rocky Linux. If you mean support of EL clients.
For the installation of Foreman itself, I don’t think there are any short-term plans. The supported OS list is pretty extensive: CentOS, RHEL, Scientific/Oracle, Ubuntu, Debian. It’s insane how the installer team is able to cover all of this, kudos!
First of all I pretty clearly understood this question to be about “supported Platform for Foreman”, which I understood to mean: “Install Foreman on Rocky”.
I think the question for what OSes there are clients has been answered extensively in this thread. However, @lzap, I was wonderung if you could expand on your “supported OS list for the installation of Foreman itself”: Does CentOS here mean CentOS Stream? Or does it mean CentOS 7 for as long as we continue to support EL7 and then nothing?
Looking in the documentation, it has only one supported OS, “Enterprise Linux 8”. Would be great if CentOS Stream 8, AlmaLinux 8 and Rocky Linux 8 can be added to the documentation if they are supported.
Maybe adding a sentence like: “Foreman is tested on bla, and is often used on the most common Enterprise Linux 8 like distributions, including foo, bar, baz.” to the documentation would give users more confidence what the collective community considers sane/has experience with?
Sure there may be a 1000 niche derivatives of EL8, but they really are not all equal.
But what is “common”? What is the criteria for “common”? Number of users? Numbers of user feedback in the community? Personal experience from developers? And what if “experience” is there but also in part negative, e.g. for Oracle Linux for which there are a few problems IIRC.
And then what if someone from another distro comes and says, hey, we are fully binary-compatible, too, and I have tested it and it works, why don’t you mention my distro as well? Why it’s only the big ones everyone already knows about?
I see those subjective, selective lists always a little bit skeptic…
