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-doc:`Kolla support matrix <support_matrix>`.
