NFS Mounts
The latest helm (version 3) needs its repo updated so it can find useful things like the nfs-client-provisioner chart.
helm repo add stable https://kubernetes-charts.storage.googleapis.com
Then we can install our containers NFS mount point.
helm install sgcontainers stable/nfs-client-provisioner --set storageClass.name=s3-containers --set nfs.server=192.168.2.21 --set nfs.path=/proxy-containers --set nfs.mountOptions="{nolock,hard}"
