<p>I'm converting volume gp2 to volume gp3 for EKS but getting this error.<br />
<em><strong>Failed to provision volume with StorageClass &quot;gp3&quot;: invalid AWS VolumeType &quot;gp3&quot;</strong></em><br />
This is my config.</p>

<p>I'm using Kubernetes version 1.18.<br />
Can someone help me. Thanks!</p>

<p>I found the solution to use volume <code>gp3</code> in storage class on EKS.</p>
<ol>
<li>First, you need to install <code>Amazon EBS CSI driver</code> with offical instruction <a href="https://docs.aws.amazon.com/eks/latest/userguide/ebs-csi.html" rel="nofollow noreferrer">here</a>.</li>
<li>The next, you need to create the storage class <code>ebs-sc</code> after <code>Amazon EBS CSI driver</code> is installed, example:</li>
</ol>
<hr />
<pre><code>cat &lt;&lt; EOF | kubectl apply -f -
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: ebs-sc
provisioner: ebs.csi.aws.com
parameters:
  type: gp3
reclaimPolicy: Retain
volumeBindingMode: WaitForFirstConsumer
EOF
</code></pre>
<p>So, you can use volume <code>gp3</code> in storage class on EKS.<br />
You can check by deploying resources:</p>
<pre><code>cat &lt;&lt; EOF | kubectl apply -f -
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: ebs-gp3-claim
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: ebs-sc
---
apiVersion: v1
kind: Pod
metadata:
  name: app-gp3-in-tree
spec:
  containers:
  - name: app
    image: nginx
    volumeMounts:
    - name: persistent-storage
      mountPath: /usr/share/nginx/html
  volumes:
  - name: persistent-storage
    persistentVolumeClaim:
      claimName: ebs-gp3-claim
EOF
</code></pre>
