Configuring Posit Connect with an NFS-backed PersistentVolume

This example deploys Posit Connect with a single PersistentVolume backed by an NFS server.

The PersistentVolume allows setting NFS mountOptions and it creates a StorageClass that Posit Connect then takes advantage of when it creates its PersistentVolumeClaim.

Both the PVC and PV will be left around after the helm release is removed (for manual cleanup) due to the persistentVolumeReclaimPolicy: Retain setting.

To use this example you will need:

• a license file or key
• a ReadWriteMany POSIX compliant storage class for sharedStorage
• a PostgreSQL database.
