|
- Ironic now has support for complex parent-child device topologies. This
|
|
|
|
|
feature, primarily targeted at orchestration of DPUs, allows nodes to have
|
|
|
|
|
parent/child relationships. This allows for more complex logic to be
|
|
|
|
|
coordinated between a node and its children. When a node with children runs
|
|
|
|
|
a step-based action, those steps can include actions to be run on the child
|
|
|
|
|
node. See `parent node documentation <https://docs.openstack.org/ironic/latest/admin/cleaning.html#parent-nodes>`_

|
|
|
- Ironic now has basic support for servicing nodes. Servicing allows
|
|
|
|
|
operators to use steps, like you would for cleaning, to perform service
|
|
|
|
|
on deployed nodes in ``ACTIVE`` state. Previously, Ironic would not
|
|
|
|
|
perform operations on active nodes. See

|
|
|
|
|
- Ironic has promoted support for firmware upgrading and information to a
|
|
|
|
|
new interface and API named ``FirmwareInterface``. This includes new API
|
|
|
|
|
support, at ``/v1/nodes/{node_ident}/firmware`` for getting firmware
|
|
|
|
|
information. In addition, operators can use the csteps provided by the new
|
|
|
|
|
``FirmwareInterface`` their firmware upgrade process for step-based
|
|
|
|
|
automations, such as deployment, cleaning, or servicing. While the structure
|
|
|
|
|
and API is in place for firmware management, our first driver, for redfish
|
|
|
|
|
hardware, is coming next release.
|
|
|
|
|
- Additional steps for servicing, cleaning, and deployment have been added.
|
|
|
|
|
The first new step, ``wait``, waits for a specified amount of time or
|
|
|
|
|
until the next heartbeat. The second new step, ``hold``, stops evaluation
|
|
|
|
|
of steps until the ``unhold`` verb is submitted to the provision state API
|
|
|
|
|
for that node. When a node is held, it will be parked a new "hold"
|
|
|
|
|
provision_state, either ``clean hold``, ``deploy hold`` or
|
|
|
|
|
``service hold``. Additionally, Ironic has added support for power control
|
|
|
|
|
via steps named, ``power_on``, ``power_off``, and ``reboot``; deployers who
|
|
|
|
|
already have custom steps with these names must rename them. These new steps
|
|
|
|
|
are useful for integrating with external systems that need to perform
|
|
|
|
|
actions on a node or for orchestrating complex workflows involving child
|
|
|
|
|
nodes.
|
|
|
|
|
- Ironic conductor services now honor the value of
|
|
|
|
|
``[DEFAULT]/graceful_shutdown_timeout``, waiting that number of seconds
|
|
|
|
|
to complete operations before forcing them to abort.
|
|
|
|
|
- Operators are now able to disable MD5 use to verify images in Ironic by
|
|
|
|
|
setting ``[agent]/allow_md5_checksum`` to false. This option defaults
|
|
|
|
|
to ``true`` to preserve existing behavior in this release; but we expect
|
|
|
|
|
to disable MD5 support by default in a future release.
