- 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.
## Kubespray configuration
First you must define the cloud provider in `inventory/sample/group_vars/all.yml` and set it to `vsphere`.
