3 vSphere CSI driver allows you to provision volumes over a vSphere deployment. The Kubernetes historic in-tree cloud provider is deprecated and will be removed in future versions.
7 The vSphere user for CSI driver requires a set of privileges to perform Cloud Native Storage operations. Follow the [official guide](https://vsphere-csi-driver.sigs.k8s.io/driver-deployment/prerequisites.html#roles_and_privileges) to configure those.
9 ## Kubespray configuration
11 To enable vSphere CSI driver, uncomment the `vsphere_csi_enabled` option in `group_vars/all/vsphere.yml` and set it to `true`.
13 To set the number of replicas for the vSphere CSI controller, you can change `vsphere_csi_controller_replicas` option in `group_vars/all/vsphere.yml`.
15 You need to source the vSphere credentials you use to deploy your machines that will host Kubernetes.

43 To test the dynamic provisioning using vSphere CSI driver, make sure to create a [storage policy](https://github.com/kubernetes/cloud-provider-vsphere/blob/master/docs/book/tutorials/kubernetes-on-vsphere-with-kubeadm.md#create-a-storage-policy) and [storage class](https://github.com/kubernetes/cloud-provider-vsphere/blob/master/docs/book/tutorials/kubernetes-on-vsphere-with-kubeadm.md#create-a-storageclass), then apply the following manifest:
48 kind: PersistentVolumeClaim
57 storageClassName: Space-Efficient
67 imagePullPolicy: IfNotPresent
73 - mountPath: /usr/share/nginx/html
74 name: csi-data-vsphere
76 - name: csi-data-vsphere
77 persistentVolumeClaim:
78 claimName: csi-pvc-vsphere
82 Apply this conf to your cluster: ```kubectl apply -f nginx.yml```
84 You should see the PVC provisioned and bound:
88 NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
89 csi-pvc-vsphere Bound pvc-dc7b1d21-ee41-45e1-98d9-e877cc1533ac 1Gi RWO Space-Efficient 10s
92 And the volume mounted to the Nginx Pod (wait until the Pod is Running):
95 kubectl exec -it nginx -- df -h | grep /usr/share/nginx/html
96 /dev/sdb 976M 2.6M 907M 1% /usr/share/nginx/html
