Volume resize doesn’t be reflected in Kubernetes

Hi there,

What I usually do with the DigitalOcean Managed Kubernetes Clusters is to use a PVC as described here in order to attach block storage to my clusters:

https://docs.digitalocean.com/products/kubernetes/how-to/add-volumes/

Here is an example configuration:

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: my-csi-app-set
spec:
  selector:
    matchLabels:
      app: mypod
  serviceName: "my-frontend"
  replicas: 1
  template:
    metadata:
      labels:
        app: mypod
    spec:
      containers:
      - name: my-frontend
        image: busybox
        args:
        - sleep
        - infinity
        volumeMounts:
        - mountPath: "/data"
          name: csi-pvc
  volumeClaimTemplates:
  - metadata:
      name: csi-pvc
    spec:
      accessModes:
      - ReadWriteOnce
      resources:
        requests:
          storage: 5Gi
      storageClassName: do-block-storage 

After that rather than resizing the block storage itself directly, to resize the volume, you can change the storage value directly via the PVC definition.

Or you could use kubectl edit pvc <pvc-name> and then increase the requested volume size.

Best,

Bobby
