Cluster update known issues¶
This section lists the cluster update known issues with workarounds for the Mirantis OpenStack for Kubernetes release 22.4.
 The ‘ironic-conductor’ Pod fails after the management cluster upgrade¶
After the Container Cloud management cluster upgrade from 2.19.0 to 2.20.0,
ironic-conductor Pod gets stuck in the
CrashLoopBackOff state. The
issue occurs due to the race condition between the
ironic-conductor-http containers of the
ironic-conductor Pod that try
ca-bundle.pem simultaneously but from different users.
As a workaround, run the following command:
kubectl -n openstack exec -t <failedPodName> -c ironic-conductor-http -- chown 42424:42424 /certs/ca-bundle.pem
 MetalLB speaker fails to announce the LB IP for the Ingress service¶
After updating the MOSK cluster, MetalLB speaker may fail to announce the Load Balancer (LB) IP address for the OpenStack Ingress service. As a result, the OpenStack Ingress service is not accessible using its LB IP address.
The issue may occur if the MetalLB speaker
nodeSelector selects not all
the nodes selected by
nodeSelector of the OpenStack Ingress service.
The issue may arise and disappear when a new MetalLB speaker is being selected by the MetalLB Controller to announce the LB IP address.
The issue occurs since MOSK 22.2 after
externalTrafficPolicy was set to
local for the OpenStack Ingress
Select from the following options:

This option is preferable in the following cases:
If not all cluster nodes have connection to the external network
If the connection to the external network cannot be established
If network configuration changes are not desired
If network configuration is allowed and if you require the
