# Verify VAST CSI Driver Deployment

To verify your VAST CSI Driver deployment, test it by launching an application using a Persistent Volume Claim (PVC).

In the following example, VAST CSI Driver will create a PVC by provisioning a volume of 1Gi from VAST using the `vastdata-filesystem` storage class. It will create a set of 5 pods running an application consisting of Docker containers with mounts to that volume. The application is a shell program that appends a date to a text file.

To verify the deployment with a test application:

1. Create a Kubernetes YAML configuration file for a PVC as follows:

```plaintext
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: vast-pvc-1
spec:
  accessModes:
  - ReadWriteMany
  resources:
    requests:
      storage: 1Gi
  storageClassName: vastdata-filesystem
```
2. Apply the PVC configuration file:

```plaintext
kubectl apply -f <filename>.yaml
```
3. Verify that the PVC has been created with the following commands:

```plaintext
kubectl get pvc
```

```plaintext
kubectl get pv
```
4. Create a Kubernetes YAML configuration file for the test application:

```plaintext
kind: StatefulSet
apiVersion: apps/v1
metadata:
  name: test-app-1
spec:
  serviceName: "test-service-1"
  replicas: 5
  selector:
    matchLabels:
      app: test-app-1
  template:
    metadata:
      labels:
        app: test-app-1
        role: test-app-2
    spec:
      containers:
        - name: my-frontend
          image: busybox
          volumeMounts:
          - mountPath: "/shared"
            name: my-shared-volume
          command: [ '/bin/sh', '-c', 'while true; do date -Iseconds >> /shared/$HOSTNAME; sleep 1; done' ]
      volumes:
        - name: my-shared-volume
          persistentVolumeClaim:
            claimName: vast-pvc-1
```
5. Apply the test application configuration file:

```plaintext
kubectl apply -f <filename>.yaml
```
6. Monitor the VAST Cluster path specified in the definition of the `vastdata-filesystem` storage class. You will see a PVC per container, in this example 5. In each, a date will be appended to a text file.
