Support Matrix

Supported Operating Systems

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

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 Bookworm (12)
• Rocky Linux 9
• Ubuntu Jammy (22.04)
• 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

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