I've recently started using NFS volumes for my clusters on-prem. This is the simplest and best solution for me, however it seems pretty limited in regards to the actual mounts options.
Is there anyway to set mount options on the node/cluster in the volume.yml files?
I have application that requires a specific version and also these mount options for performance.
apiVersion: v1
kind: PersistentVolume
metadata:
name: nfs
spec:
capacity:
storage: 1Mi
accessModes:
- ReadWriteMany
nfs:
# FIXME: use the right IP
server: 10.244.1.4
path: "/"Is there anyway to add mount flags here?
It is possible and it's been GA in Kubernetes since 1.8.
apiVersion: v1

Not really. Not supported by Kubernetes yet.
If you really need very specific NFS options, for now, I would recommend using hostPath.
This way you can mount your NFS volumes on a specific mount point on your host and have your Kubernetes pods use that.
