As you may recall, the CentOS Linux 8 (as opposed to CentOS Stream 8)
is reaching its EOL (End Of Life) Dec 31st, 2021 (that is, in eleven
Due to that, the OpenDev team (that hosts kolla's repos and the CI/CD
that we rely on) has decided to drop the EOLed images January 14th,
This impacts both Kolla and Kolla Ansible in subtle ways - both
operator-wise and contributor-wise.
The EM (Extended Maintenance) branches, Train and Ussuri, in both
projects, rely solely on CentOS Linux 8, the Stream variant is *not*
This means that in 2022 we are forced to cease to test these branches
against CentOS Linux 8 (we will still test the two other distros -
Ubuntu and Debian).
Operators are advised to upgrade to Victoria or (preferably) later
(psst, go Xena).
Furthermore, CentOS Linux 8 is currently supported in Victoria but
this support will also end naturally with 2022 on the horizon.
Operators are advised to migrate to CentOS Stream 8 and images based on it.
