Challenge

Create a PersistentVolume
1. Create a PersistentVolume called host-storage-pv with a storage capacity of 1Gi in the acgk8s context. Configure this PersistentVolume so that volumes that use it can be expanded in the future.
  
  Note: This may require you to create additional objects.
2. Configure the PersistentVolume to use a hostPath for storage located at /etc/data.
3. Configure the PersistentVolume so that it can be automatically reused if all claims are deleted.
Challenge

Create a Pod That Uses the PersistentVolume for Storage
1. Create a Pod called pv-pod in the auth Namespace. Configure this Pod so that it uses the host-storage-pv PersistentVolume for storage.
  
  Note: This will require the creation of a PersistentVolumeClaim in the same namespace as the Pod.
2. Name the PersistentVolumeClaim host-storage-pvc. Give your PersistentVolumeClaim a size of 100Mi.
3. Use the busybox image for this Pod, and configure it to run the command sh -c while true; do echo success > /output/output.log; sleep 5; done.
4. Mount the volume that uses the PersistentVolume for storage, such that the /output directory ultimately writes to the PersistentVolume.
Challenge

Expand the PersistentVolumeClaim

Expand the PersistentVolumeClaim so that the requested storage size is 200Mi.
