The pod `alibaba-disk-csi-driver-controller` mounts the secret:
$ cat assets/controller.yaml
...
containers:
- name: provisioner-kube-rbac-proxy
volumeMounts:
- mountPath: /etc/tls/private
name: metrics-serving-cert
volumes:
- name: metrics-serving-cert
secret:
secretName: alibaba-disk-csi-driver-controller-metrics-serving-cert
Hence, if the secret is updated (e.g. as a result of CA cert update), the Pod must be restarted
[STOR-1439] Automatically restart `alibaba-disk-csi-driver-controller` pods when the secret `alibaba-disk-csi-driver-controller-metrics-serving-cert` is updated
Since the blocker bug https://issues.redhat.com/browse/OCPBUGS-17652 , we couldn't install alibaba cloud clusters on 4.14, currently I haven't done the pre/post merge test about this user story.
Test passed with the pre merged build `4.14.0-0.ci.test-2023-09-01-085811-ci-ln-rxpny9b-latest` (build with openshift/cluster-cloud-controller-manager-operator#276 which solved the install failed blocker issue)
