Verify VAST COSI Driver Deployment

To verify your VAST COSI Driver deployment, provision a bucket on the VAST cluster and prepare credentials for accessing the bucket:

Create a Kubernetes YAML configuration file that defines bucket access:

kind: BucketAccessClass
apiVersion: objectstorage.k8s.io/v1alpha1
metadata:
 name: sample-bac
driverName: csi.vastdata.com
authenticationType: KEY
---
kind: BucketAccess
apiVersion: objectstorage.k8s.io/v1alpha1
metadata:
 name: sample-access
spec:
 bucketClaimName: sample-bucket
 bucketAccessClassName: sample-bac
 credentialsSecretName: my-super-secret
---
kind: BucketClaim
apiVersion: objectstorage.k8s.io/v1alpha1
metadata:
 name: sample-bucket
spec:
 bucketClassName: vastdata-bucket
 protocols:
 - s3

Apply the bucket access configuration file:
```
kubectl apply -f <filename>.yaml
```
Verify that a newly created bucket vastdata-bucket is displayed as a view in the VAST Cluster's Web UI.
Verify that the newly created user named vastdata-bucket is displayed in the VAST Cluster's Web UI.
Verify that a newly created Kubernetes secret my-super-secret is listed in the output of the following command:
```
kubectl get secret
```

Create a Kubernetes YAML configuration file for a pod that uses the newly created Kubernetes secret:

apiVersion: v1
kind: Pod
metadata:
 name: awscli
spec:
 containers:
   - name: awscli
     image: amazon/aws-cli
     command: ["sleep"]
     args: ["9999999999"]
     volumeMounts:
       - name: cosi-secrets
         mountPath: /data/cosi
         readOnly: true
 volumes:
 - name: cosi-secrets
   secret:
     secretName: my-super-secret

Apply the pod configuration file:
```
kubectl apply -f <filename>.yaml
```
Verify the content of the Kubernetes secret:
```
kubectl exec -it awscli cat /data/cosi/BucketInfo
```
The JSON output lists the VAST Cluster endpoint, the access key and the secret key, which can be used to access the newly created bucket.
