Recently I configured Azure Files provisioned statically according to this manual: https://docs.microsoft.com/en-us/azure/aks/azure-files-volume I have run my application on a pod and mounted Azure Files to it. Unfortunately, when I try to create some file on this Azure Files storage from my application, I get java.io.IOException: Permission denied... Is there any way to change permissions of this Azure Files? Below is the yaml file of my deployment:

apiVersion: apps/v1beta1
kind: Deployment

    name: vm-wojtek

    replicas: 1

                  ports:
                  - containerPort: 8080
                  - containerPort: 8443
                  imagePullPolicy: Always
                  volumeMounts:
                  - mountPath: "/mnt/azure"
                    name: volume
                    readOnly: false
            volumes:
                - name: volume
                  azureFile:
                      secretName: azure-secret
                      shareName: vm-share
                      readOnly: false

EDIT:

Below is the output of kubectl get pod -o yaml
