I have created the EKS cluster.
Then follow the document (https://eksctl.io/usage/eksctl-karpenter/) to add karpenter support,
metadata:
name: eks-dev
region: ap-southeast-2
version: "1.22"
+ tags:
+ karpenter.sh/discovery: eks-dev
+iam:
+ withOIDC: true # required
+karpenter:
+ version: '0.9.0'
managedNodeGroups:
- name: spot
but when I upgrade it, nothing happen.
$ eksctl upgrade cluster -f eks-dev.yaml --approve

The note is about to igonre the change for VPC, but Karpenter change is not related to vpc.
So how can I fix this issue?
Support for karpenter only applies to new cluster, it has no effect to existing cluster. You can manually install karpenter on existing cluster following this guide.
