# vSphere CSI Driver
|
|
|
|
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.
|
|
|
|
To enable vSphere CSI driver, uncomment the `vsphere_csi_enabled` option in `group_vars/all/vsphere.yml` and set it to `true`.
|
|
|
|
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`.
|
|
|
|
You need to source the vSphere credentials you use to deploy your machines that will host Kubernetes.

## Usage example
|
|
|
|
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:
|
|
|
|
```yml
|
|
---
|
|
apiVersion: v1
|
|
kind: PersistentVolumeClaim
|
|
metadata:
|
|
name: csi-pvc-vsphere
|
|
spec:
|
|
accessModes:
|
|
- ReadWriteOnce
|
|
resources:
|
|
requests:
|
|
storage: 1Gi
|
|
storageClassName: Space-Efficient
|
|
|
|
---
|
|
apiVersion: v1
|
|
kind: Pod
|
|
metadata:
|
|
name: nginx
|
|
spec:
|
|
containers:
|
|
- image: nginx
|
|
imagePullPolicy: IfNotPresent
|
|
name: nginx
|
|
ports:
|
|
- containerPort: 80
|
|
protocol: TCP
|
|
volumeMounts:
|
|
- mountPath: /var/lib/www/html
|
|
name: csi-data-vsphere
|
|
volumes:
|
|
- name: csi-data-vsphere
|
|
persistentVolumeClaim:
|
|
claimName: csi-pvc-vsphere
|
|
readOnly: false
|
|
```
|
|
|
|
Apply this conf to your cluster: ```kubectl apply -f nginx.yml```
|
|
|
|
You should see the PVC provisioned and bound:
|
|
|
|
```ShellSession
|
|
$ kubectl get pvc
|
|
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
|
|
csi-pvc-vsphere Bound pvc-dc7b1d21-ee41-45e1-98d9-e877cc1533ac 1Gi RWO Space-Efficient 10s
|
|
```
|
|
|
|
And the volume mounted to the Nginx Pod (wait until the Pod is Running):
|
|
|
|
```ShellSession
|
|
kubectl exec -it nginx -- df -h | grep /var/lib/www/html
|
|
/dev/sdb 976M 2.6M 907M 1% /var/lib/www/html
|
|
```
|
|
|
