      Sometime between 4.20.0-0.nightly-2025-07-31-063120 and 4.20.0-0.ci-2025-08-12-172211 Ironic started using port 8089, i.e.

      [jcaamano@sdn-08 ~]$ oc --insecure-skip-tls-verify --request-timeout=20s rsh -n openshift-ovn-kubernetes -c ovnkube-controller ovnkube-node-75q26 ss -apn | grep 8089
tcp   LISTEN    0      5                                                [::1]:8089                             [::]:*      users:(("ironic",pid=13669,fd=6))

      At the same time k-nmstate operator running as host-networking pod uses 8089. As a result, k-nmstate cannot any more start because 8089 is already used by Ironic.

      As per gentlemen's agreement, k-nmstate was there first so Ironic should move to use another port.

      At the same time, we should document (https://github.com/openshift/enhancements/blob/master/dev-guide/host-port-registry.md) the new port Ironic is going to use (k-nmstate will document theirs too).
