Deploy EBS CSI Driver

On EKS, you can create Persistent Volume Claims (PVCs) backed by EBS volumes. Prior Kubernetes 1.23, you could use the gp2 storage class that was available by default. In 1.23 or later EKS clusters you need to deploy the Elastic Block Store (EBS) Container Storage Interface (CSI) driver in order to use the gp2 storage class. Nevertheless, we recommend that you install this driver regardless of the Kubernetes version in your cluster.
