💡 Example Usage

This repository contains example manifests that demonstrate the usage of the Linode BlockStorage CSI Driver. These manifests create a PersistentVolumeClaim (PVC) using the linode-block-storage-retain storage class and then consume it in a minimal pod.

You can find more example manifests here.

Creating a PersistentVolumeClaim

kubectl create -f https://raw.githubusercontent.com/linode/linode-blockstorage-csi-driver/master/internal/driver/examples/kubernetes/csi-pvc.yaml
kubectl create -f https://raw.githubusercontent.com/linode/linode-blockstorage-csi-driver/master/internal/driver/examples/kubernetes/csi-app.yaml

Verify the Pod and PVC:

kubectl get pvc/csi-example-pvc pods/csi-example-pod
kubectl describe pvc/csi-example-pvc pods/csi-example-pod

Persist Data Example:

  1. Write Data:

    kubectl exec -it csi-example-pod -- /bin/sh -c "echo persistence > /data/example.txt; ls -l /data"

  2. Delete and Recreate Pod:

    kubectl delete pods/csi-example-pod
kubectl create -f https://raw.githubusercontent.com/linode/linode-blockstorage-csi-driver/master/pkg/linode-bs/examples/kubernetes/csi-app.yaml

  3. Verify Data Persistence:

    sleep 30
kubectl exec -it csi-example-pod -- /bin/sh -c "ls -l /data; cat /data/example.txt"
