upgrade:
- |
Support for token-less agents has been removed as the token-less agent
support was deprecated in the Ussuri development cycle. The ironic-python-agent
must be updated to 6.1.0 or higher to support communicating with the
Ironic deployment after upgrade. This will generally require deployment,
cleaning, and rescue kernels and ramdisks to be updated. If this is not
done, actions such as cleaning and deployment will time out as the agent
will be unable to record heartbeats with Ironic. For more information,
please see the `agent token <https://docs.openstack.org/ironic/latest/admin/agent-token.html>`_
documentation.
security:
- |
Ramdisks supporting agent token are now globally required by Ironic.
As this is a core security mechanism, it cannot be disabled and support
for the ``[DEFAULT]require_agent_token`` configuration parameter has been
removed as tokens are now always required by Ironic. For more information,
please see the `agent token <https://docs.openstack.org/ironic/latest/admin/agent-token.html>`_
documentation.
