Creating a ClusterRole to Access a PV in Kubernetes

In this hands-on lab, you will be tasked with accessing a persistent volume from a pod in order to view the available volumes inside the Kubernetes cluster. By default, pods cannot access volumes directly, so you will also need to create a cluster role to provide authorization to the pod. Additionally, you cannot access the API server directly without authentication, so you will need to run kubectl in proxy mode to retrieve information about the volumes.

Request access to the PV from the pod
1. Open a shell inside the container.
2. From the container shell prompt, issue the curl command to request persistent volumes from the API server.
