This document and script are based on the following documents:
- https://two-oes.medium.com/openshift-4-8-and-above-with-nfs-subdir-external-provisioner-9b6b614194b7

This procedure will essentially deploy a new storage provisioner to your cluster.
Requirements
This script can only be executed once:
- your cluster has been provisioned.
- openshift has been installed.
Input
This script takes 1 mandatory parameter - the UPI hostname in a Resource Hub Quickcluster.
It can be found in the Cluster Information section.
It takes another optional parameter - a path to an SSH private key to be used for authenticating with
the host. When not provided, the script will instead use the private key at ~/.ssh/id_rsa.
Cluster Information
Username: quickcluster
Hosts:
- upi-0.shebertquick.lab.upshift.rdu2.redhat.com ( 10.0.91.104 )
The script uses this info to obtain credentials in order to configure the storage on your cluster
Usage
# setup-nfs-quickcluster.sh upi-0.shebertquick.lab.upshift.rdu2.redhat.com
Testing
Once the scripts executes, run the following command to test the setup:
% export KUBECONFIG=/tmp/kubeconfig
% oc new-project test-pvc
% oc create -f templates/test-pvc.yaml
% oc get pvc
The status should be Bound
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
test-claim Bound pvc-1392e83f-60ec-4caf-b71b-8d040b8becd5 100Mi RWX managed-nfs-storage 6s
You may now run the bootstrap scripts.
