How to use volume gp3 in storage class on EKS?-CodePudding

I'm converting volume gp2 to volume gp3 for EKS but getting this error.
Failed to provision volume with StorageClass "gp3": invalid AWS VolumeType "gp3"
This is my config.

StorageClass

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    storageclass.kubernetes.io/is-default-class: "true"
  name: gp3
parameters:
  fsType: ext4
  type: gp3
provisioner: kubernetes.io/aws-ebs
reclaimPolicy: Retain
allowVolumeExpansion: true
volumeBindingMode: WaitForFirstConsumer

PVC

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  labels:
    app: test-pvc
  name: test-pvc
  namespace: default
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: gp3

When I type kubectl describe pvc/test. This is response:

I'm using Kubernetes version 1.18.
Can someone help me. Thanks!

CodePudding user response：

The default k8s storage driver support up to gp2 only. To use gp3 you need to install AWS EBS CSI driver. Here's the official instruction to install the driver.

CodePudding user response：

Thank @gohm'c, but I would like to add a note that need to create the storage class "ebs-sc" after AWS EBS CSI driver is installed, example:

cat << 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
