Shared Azure File Storage with Statefulset on AKS - azure

Question

I have a Statefulset with 3 instances on Azure Kubernetes 1.16, where I try to use Azure File storage to create a single file share for the 3 instances.
I use Azure Files dynamic where all is declarative i.e. storage account, secrets, pvc's and pv's are created automatically.
Manifest with VolumeClaimTemplate
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: xxx
spec:
replicas: 3
...
volumeClaimTemplates:
- metadata:
name: xxx-data-shared
spec:
accessModes: [ ReadWriteMany ]
storageClassName: azfile-zrs-sc
resources:
requests:
storage: 1Gi
The StorageClass:
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: azfile-zrs-sc
provisioner: kubernetes.io/azure-file
reclaimPolicy: Retain
volumeBindingMode: WaitForFirstConsumer
mountOptions:
- dir_mode=0777
- file_mode=0777
- uid=0
- gid=0
- mfsymlinks
- cache=strict
parameters:
resourceGroup: xxx
skuName: Standard_ZRS
shareName: data
Instead of one share, I end up with 3 pv's each referring to a separate created Azure Storage Account each with a share data.
Question: Can I use the Azure Files dynamic, with additional configuration in the manifest to get a single file share? Or will I have to do Static?

Answer 1

Turns out that volumeClaimTemplates is not the right place (reference).
Instead use persistentVolumeClaim.
For Azure File Storage this becomes:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: data-shared-claim
spec:
accessModes:
- ReadWriteMany
storageClassName: azfile-zrs-sc
resources:
requests:
storage: 1Gi
And refer to it in the manifest:
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: xxx
spec:
replicas: 3
...
template:
spec:
containers:
...
volumeMounts:
- name: data-shared
mountPath: /data
volumes:
- name: data-shared
persistentVolumeClaim:
claimName: data-shared-claim
