We followed the k8s documents to create Highly Available clusters with kubeadm https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/high-availability/.
Our cluster is built with 3 masters & 5 workers using VM guests and RHEL as an OS.
We were not aware at the time about using vSphere as a cloud provider for storage .. We would like to add vSphere as a cloud provider..
Looking around all the info assumes that we will add vSphere as a cloud provider at the time of building the cluster as illustrated in https://cloud-provider-vsphere.sigs.k8s.io/tutorials/kubernetes-on-vsphere-with-kubeadm.html or https://theithollow.com/2020/01/08/deploy-kubernetes-on-vsphere/
Anyone can help me how to add vSphere to an exiting running cluster.
