Marcin Juszkiewicz 3c6959df33 Default to Rocky Linux instead of CentOS Stream 
We agreed that CentOS Stream 9 images are not published as we keep it
for CI use only (to check potential failures before it hits RHEL).

We recommend Rocky Linux 9 instead.

Support Matrix

Supported Operating Systems

Kolla Ansible supports the following host Operating Systems (OS):

Note

CentOS 7 is no longer supported as a host OS. The Train release supports both CentOS 7 and 8, and provides a route for migration. See the Kolla Ansible Train documentation for information on migrating to CentOS 8.

Note

CentOS Linux 8 (as opposed to CentOS Stream 8) is no longer supported as a host OS. The Victoria release will in future support both CentOS Linux 8 and CentOS Stream 8, and provides a route for migration.

Note

CentOS Stream 9 is supported as a host OS while Kolla does not publish CS9 based images. Users can build them on their own. We recommend using Rocky Linux 9 images instead.

  • CentOS Stream 9
  • Debian Bullseye (11)
  • openEuler 22.03 LTS
  • Rocky Linux 9
  • Ubuntu Jammy (22.04)

Supported container images

For best results, the base container image distribution should match the host OS distribution. The following values are supported for kolla_base_distro:

  • centos
  • debian
  • rocky
  • ubuntu

For details of which images are supported on which distributions, see the Kolla support matrix <support_matrix>.
