Hello *,

due to CentOS 8 being EOL to the end of this year I did some
investigation on how to properly update and Openstack environment
running CentOS 8 and Openstack Ussuri.

If you just want to update the operation system it seems like
there is no problem at all. Just do a

 > dnf switch stream
and
 > dnf distro-sync

Since openstack has proven its complexity i can't imagine that
it is that simple if you are running an openstack environment
on it :D


The basic process to update the OS should be just that. Note that the process and the caveats may depend on the deployment tooling (tripleo, kolla, packstack or custom one) and any customizations that you may have done if so.

We will do some basic testing to do some advice about issues and workarounds that you may need but note that you may hit different issues depending on your case so the best recommendation is always test in a non-production environment similar to production ones.

We will publish our findings.
 
Any chance to update to CentOS stream without breaking the environment?

If not I don't see any restrictions in updating both, the openstack
version and the operating system version. But may you tell me if there
is an migration path to successfully update from CentOS 8 to CentOS
stream?

Do i have to update CentOS before updating Openstack or wise versa?
Do you have any information on how to update?

I would separate OS update and OpenStack update. I'd try to update OS first, and then OpenStack version.


If this was already discussed please send me a link.
I found the following on the internet:
http://lists.openstack.org/pipermail/openstack-discuss/2021-February/020651.html

That was already useful but didn't answered my questions entirely.


Best regards
