Supported Operating Systems
~~~~~~~~~~~~~~~~~~~~~~~~~~~

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

.. note::

   CentOS Stream 10 is supported as a host OS while Kolla does not publish CS10
   based images. Users can build them on their own. We recommend using Rocky
   Linux 10 images instead.

* CentOS Stream 10
* Debian Trixie (13)
* Rocky Linux 10
* 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-doc:`Kolla support matrix <support_matrix>`.
