I am currently deploying JupyterHub on a Kubernetes cluster. I am able to get to the login screen, but am unable to spawn users.
I suspect the cause may be in the persistent volume settings. But I have no idea how to improve it 
I have included the yaml file below.
# storage-class.yaml
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: local-storage-class
annotations:
storageclass.kubernetes.io/is-default-class: "true"
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer
# pv.yaml
apiVersion: v1
kind: PersistentVolume
metadata:
name: local-pv
spec:
capacity:
storage: 1Gi
accessModes:
- ReadWriteOnce
volumeMode: Filesystem
persistentVolumeReclaimPolicy: Retain
storageClassName: local-storage-class
local:
path: /mnt/disks/vol1
nodeAffinity:
required:
nodeSelectorTerms:
- matchExpressions:
- key: kubernetes.io/hostname
operator: In
values:
- sample-worker
- sample-worker2
# pvc.yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: local-pvc
spec:
accessModes:
- ReadWriteOnce
storageClassName: local-storage-class
resources:
requests:
storage: 1Gi
The current status of the cluster is as follows
$ kubectl get all -A
