Supported Operating Systems

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

Note

CentOS Stream 9 and 10 is supported as a host OS while Kolla does not publish CS9/10 based images. Users can build them on their own. We recommend using Rocky and 10 images instead.

  • CentOS Stream 9

  • CentOS Stream 10

  • Debian Bookworm (12)

  • Rocky Linux 9

  • Ubuntu Noble (24.04)

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

Note

In order to use CentOS Stream 10 please set kolla_base_distro_version to stream10 and to 10 for using Rocky Linux 10.

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