Comment 1 Aleksandra Malykhin 2022-05-26 13:09:10 UTC

Verified with kubernetes-nmstate-operator.4.11.0-202205250927  

1. Deploy the sno cluster
2. Install KNMState
3. Check the pods

[root@ocp-edge39 ~]# oc get pods 
NAME                                    READY   STATUS    RESTARTS   AGE
nmstate-cert-manager-7ff9955f99-kkbnx   1/1     Running   0          53s
nmstate-handler-rc9xc                   1/1     Running   0          54s
nmstate-operator-67744d4779-7kkmv       1/1     Running   0          87s
nmstate-webhook-66b4f6bd6-v6wmk         1/1     Running   0          53s

Result: 
Only one instance of webhook pod is created, all pods are OK

Additional update case:

1. Deploy the sno cluster
2. Install KNMState 4.11 (not latest)
3. Check the pods (one instance of webhook pod)
4. Update the KNMState to the latest
5. Check the pods (one instance of webhook pod, all pods are OK)

Additional upgrade case:

1. Deploy the sno cluster
2. Install KNMState 4.10
3. Check the pods (two instances of webhook pod)
4. Upgrade the KNMState to 4.11
5. Check the pods (one instance of webhook pod, all pods are OK)
