Fedora 36 is EOL, also opendev is dropping support for Fedora images completely since interest in running jobs on that platform is no longer existing. CentOS 9 Stream has evolved as replacement platform for new features. Only drop the Zuul configuration and the tag in stack.sh for now plus update some docs. Cleanup of the deployment code will be done in a second step. Change-Id: Ica483fde27346e3939b5fc0d7e0a6dfeae0e8d1e

Overview
|
|
========
|
|
|
|
DevStack has evolved to support a large number of configuration options
|
|
and alternative platforms and support services. That evolution has grown
|
|
well beyond what was originally intended and the majority of
|
|
configuration combinations are rarely, if ever, tested. DevStack is not
|
|
a general OpenStack installer and was never meant to be everything to
|
|
everyone.
|
|
|
|
Below is a list of what is specifically is supported (read that as
|
|
"tested") going forward.
|
|
|
|
Supported Components
|
|
====================
|
|
|
|
Base OS
|
|
-------
|
|
|
|
*The OpenStack Technical Committee (TC) has defined the current CI
|
|
strategy to include the latest Ubuntu release and the latest RHEL
|
|
release.*
|
|
|
|
- Ubuntu: current LTS release plus current development release
|
|
- RHEL/CentOS/RockyLinux: current major release
|
|
- Other OS platforms may continue to be included but the maintenance of
|
|
those platforms shall not be assumed simply due to their presence.
|
|
Having a listed point-of-contact for each additional OS will greatly
|
|
increase its chance of being well-maintained.
|
|
- Patches for Ubuntu and/or RockyLinux will not be held up due to
|
|
side-effects on other OS platforms.
|
|
|
|
Databases
|
|
---------
|
|
|
|
*As packaged by the host OS*
|
|
|
|

|
|
|
|

Web Server

|
|
OpenStack Network

|
|
|
|
Services
|
|
--------
|
|
|
|
The default services configured by DevStack are Identity (keystone),
|
|
Object Storage (swift), Image Service (glance), Block Storage
|
|
(cinder), Compute (nova), Placement (placement),
|
|
Networking (neutron), Dashboard (horizon).
|
|
|
|
Additional services not included directly in DevStack can be tied in to
|
|
``stack.sh`` using the :doc:`plugin mechanism <plugins>` to call
|
|
scripts that perform the configuration and startup of the service.
|
|
|
|
Node Configurations
|
|
-------------------
|
|
|
|
- single node
|
|
- multi-node configurations as are tested by the gate
