[Bug] Error: failed to install Karpenter: failed to install Karpenter chart: failed to install chart: Kubernetes cluster unreachable: exec plugin: invalid apiVersion "client.authentication.k8s.io/v1alpha1" #8198
Description
What were you trying to accomplish?
We are trying to install Karpenter when deploying EKS cluster by running eksctl in a codebuild project created by AWS CDK
What happened?
We know that Karpenter can only be installed using Eksctl during first time cluster creation based on this issue and thats what we did. However, we got this error Error: failed to install Karpenter: failed to install Karpenter chart: failed to install chart: Kubernetes cluster unreachable: exec plugin: invalid apiVersion "client.authentication.k8s.io/v1alpha1"
How to reproduce it?
create a codebuild project that runs eksctl create cluster -f cluster_config.yaml in its buildspec.yaml
If using a config file, include it here, removing any sensitive information!
