nfs-provisioner

Reason:

• I don't want to have lots of small pieces of Digital Ocean Block Storage volumes

• Enables ReadWriteMany for sharing files across pods

Edit the Persistent Volume Claim to

kubectl edit pvc data-nfs-server-nfs-server-provisioner-0

Assuming we are changing from 5Gi to 10Gi

Change the keys for:

• spec.resources.request.storage

• status.capacity.storage

  spec:
    resources:
      requests:
-      storage: 5Gi
+      storage: 10Gi
  status:
    capacity:
-      storage: 5Gi
+      storage: 10Gi

Delete the StatefulSet:

kubectl delete sts --cascade=false nfs-server-nfs-server-provisioner

Change your helm custom values, I store mine in a custom.yaml file.

  persistence:
-   size: 5Gi
+   size: 10Gi

Apply changes in helm

helm upgrade nfs-server nfs-server-provisioner/ -f nfs-server-provisioner/custom.yaml
