Additional storage volumes

JupyterHub Zero to JupyterHub on Kubernetes

I have had success hosting the hub sqlite db on NFS. We are using AWS EFS to host this.

Here’s a portion of the helm chart:

hub:
  extraVolumes:
    - name: hub-db-dir
      persistentVolumeClaim:
        claimName: nfs-host-pvc

Here’s a pvc config:

apiVersion: v1 
kind: PersistentVolume 
metadata: 
  name: nfs-host-pv 
spec: 
  capacity: 
    storage: 1Gi 
  accessModes: 
    - ReadWriteMany 
  nfs: 
    server: amazon-efs-hub-storage-server
    path: "/host-hub" 
 
--- 
kind: PersistentVolumeClaim 
apiVersion: v1 
metadata: 
  name: nfs-host-pvc
spec: 
  accessModes: 
    - ReadWriteMany 
  storageClassName: "" 
  resources: 
    requests: 
      storage: 1Gi

The only thing I’ll note, is that using Helm - there was a bit of an annoyance that a basic deployment needs to be deployed, and then this change can be pushed. Little more on that was discussed here: JupyterHub hub-db-dir PV Question
