Complete this step if you are going to use VAST snapshots on your Kubernetes cluster. The Custom Resource Definitions (CRDs) installed in this step are only required for using VAST snapshots.
Run the following commands to install the CRDs for snapshots:
kubectl apply -f https://raw.githubusercontent.com/kubernetes-csi/external-snapshotter/v6.0.1/client/config/crd/snapshot.storage.k8s.io_volumesnapshotclasses.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes-csi/external-snapshotter/v6.0.1/client/config/crd/snapshot.storage.k8s.io_volumesnapshotcontents.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes-csi/external-snapshotter/v6.0.1/client/config/crd/snapshot.storage.k8s.io_volumesnapshots.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes-csi/external-snapshotter/v6.0.1/deploy/kubernetes/snapshot-controller/rbac-snapshot-controller.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes-csi/external-snapshotter/v6.0.1/deploy/kubernetes/snapshot-controller/setup-snapshot-controller.yaml
