cycle-highlights:
- Ironic has enabled RBAC support by default by changing the default
values of ``[oslo_policy]enforce_scope`` and
``[oslo_policy]enforce_new_defaults`` to ``True``. Additionally, we
added ``[DEFAULT]rbac_service_project_name`` to define a project where
users in that project are treated as having a service role.
Please see Ironic release notes for full details.
- Ironic has added the ability to drain active tasks from a conductor
before shutdown. Sending a ``SIGUSR2`` signal to an ironic-conductor
will now attempt to complete running tasks with a timeout of
``[DEFAULT]drain_shutdown_timeout``. No new tasks will be started on
the conductor while it's draining.
- Ironic now has basic testing for OVN-based deployments, using the OVN
DHCP service. This includes lightly tested support for OVN VTEP switches.
Operators considering use of this support should read
`Ironic OVN documentation <https://docs.openstack.org/ironic/latest/admin/ovn-networking.html>`_
for more information and details on limitations.
- Several Ironic drivers have been deprecated in favor of more modern,
redfish-based drivers. The ``ibmc``, ``xclarity``, and ``idrac-wsman``
drivers will be removed during a future development cycle. Operators
utilizing these drivers are encouraged to use the redfish hardware type
instead. Additionally, users of the ``ilo`` hardware type on newer ILO6-based
hardware will now be prompted to use ``redfish`` instead.
- Ironic now supports UEFI HTTP mode booting. The ``http`` boot interface is
based upon the ``pxe`` interface, and ``http-ipxe`` is based upon ``ipxe``.
- Ironic now supports in-band inspection and node auto-discovery without an
additional ironic-inspector service. An online data migration was added which
migrates inspection interface on idle nodes to ``agent`` if inspector-based
inspection is disabled, and agent-based inspection is enabled.
- Ironic will now reserve a small number of worker threads for user-interactive
API usage. Previously, an overloaded Ironic cluster could fail API calls if many
nodes performed provisioning actions at the same time.
- Ironic now supports pulling down images from a web server authenticated
using basic auth. This permits standalone Ironic users to secure their
external image repositories.
