add karpenter to eksctl config file, but no upgrade-CodePudding

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
2022-06-07 21:08:25 [!]  NOTE: cluster VPC (subnets, routing & NAT Gateway) configuration changes are not yet implemented

$

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?

CodePudding user response：

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.
