Configuring StorageClass

Prerequisites

1. Kubernetes 1.13+ (CSI 1.0).
2. The aws-ebs-csi-driver installed.

Usage

This example shows you how to write to a dynamically provisioned EBS volume with a specified configuration in the StorageClass resource.

1. Modify the StorageClass resource in storageclass.yaml as desired. For a list of supported parameters consult the Kubernetes documentation on Storage Classes.

2. Deploy the provided pod on your cluster along with the StorageClass and PersistentVolumeClaim:

   $ kubectl apply -f manifests
   
   persistentvolumeclaim/ebs-claim created
   pod/app created
   storageclass.storage.k8s.io/ebs-sc created

3. Validate the PersistentVolumeClaim is bound to your PersistentVolume.

   $ kubectl get pvc ebs-claim
   
   NAME        STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
   ebs-claim   Bound    pvc-1fb712f2-632d-4b63-92e4-3b773d698ae1   4Gi        RWO            ebs-sc         17s

4. Validate the pod successfully wrote data to the dynamically provisioned volume:

   $ kubectl exec app -- cat /data/out.txt

   ...

5. Cleanup resources:

   $ kubectl delete -f manifests
   
   persistentvolumeclaim "ebs-claim" deleted
   pod "app" deleted
   storageclass.storage.k8s.io "ebs-sc" deleted
