Attaching block storage to managed kubernetes

Posted on July 17, 2022

I would like to attach a block storage to my managed kubernetes cluster. But in the control panel when I select servers it only shows the kubernetes load balancer. Is this correct?

Looking at the docs, it shows the kubernetes config required but not how to create the block storage, or is the managed service smart enough to notice the kubernetes config and it does all the create+attach magic?

Thank you

Hi there,

Yes, you can attach a block storage to your managed cluster by following the steps here:

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

Applying the following should be sufficient:

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

This will automatically create the block storage under your account.

Let me know how it goes!

Best,

Bobby
