Support Matrix

Supported Operating Systems

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

Note

CentOS Stream 8 is no longer supported as a host OS. The Yoga release supports both CentOS Stream 8 and CentOS Stream 9 / Rocky Linux 9, 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.
