# PVC backed by NFS server
#
# For K8s environments other than GKE, you will need to modify the nfs-storage
# persistent volume to reference directly the IP address of the nfs-server:
# 1. Deploy the nfs-server resources
# 2. Get the IP address of the nfs-server with `kubectl get service nfs-server`
# 3. Replace `nfs-server.tower-nf.svc.cluster.local` with the IP address in the nfs-storage YAML
# 4. Deploy the nfs-storage PV and tower-scratch PVC
#
