 You need at first to configure your vSphere environment by following the [official documentation](https://kubernetes.io/docs/getting-started-guides/vsphere/#vsphere-cloud-provider).
 
 After this step you should have:

 - UUID activated for each VM where Kubernetes will be deployed
 - A vSphere account with required privileges
 
 If you intend to leverage the [zone and region node labeling](https://kubernetes.io/docs/reference/kubernetes-api/labels-annotations-taints/#failure-domain-beta-kubernetes-io-region), create a tag category for both the zone and region in vCenter.  The tags can then be applied at the host, cluster, datacenter, or folder level, and the cloud provider will walk the hierarchy to extract and apply the labels to the Kubernetes nodes.
