Supported Operating Systems
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Kolla Ansible supports the following host Operating Systems (OS):
.. note::
CentOS 7 is no longer supported as a host OS. The Train release supports
both CentOS 7 and 8, and provides a route for migration. See the `Kolla
Ansible Train documentation
<https://docs.openstack.org/kolla-ansible/train/user/centos8.html>`_ for
information on migrating to CentOS 8.
.. note::
CentOS Linux 8 (as opposed to CentOS Stream 8) is no longer supported as a
host OS. The Victoria release will in future support both CentOS Linux 8 and
CentOS Stream 8, 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.
* CentOS Stream 9
* 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``
* ``ubuntu``
For details of which images are supported on which distributions, see the
:kolla-doc:`Kolla support matrix <support_matrix>`.
