Do you have an existing k8s config? Running
aws eks update-kubeconfig --region <region> --name <cluster name>
Generates a ~/.kube/config.
If you already have a ~/.kube/config, there could be a conflict between the file to be generated, and the file that already exists that prevents them from being merged.
If you have a ~/.kube/config file, and you aren't actively using it, running
rm ~/.kube/config
and then attempting
aws eks update-kubeconfig --region us-east-2 --name <cluster name>
afterwards will likely solve your issue.
If you are using your ~/.kube/config file, rename it something else so you could use it later, and then run the eks command again.

update-kubeconfig — AWS CLI 2.34.36 Command Reference
The following update-kubeconfig example configures your kubectl by creating or updating the kubeconfig (with role-arn option to assume a role for cluster authentication) so that you can connect to an Amazon EKS Cluster named my-eks-cluster. aws eks update-kubeconfig \ --name my-eks-cluster \ --role-arn arn:aws:iam::111122223333:role/eksctl-EKS-Linux-Cluster-v1-24-cluster-ServiceRole-j1k7AfTIQtnM

r/Terraform on Reddit: Appending new content to KubeConfig file
July 14, 2022 -
Hey Guys ,
I've deployed a cluster on EKS ( AWS ) via terraform , and wondering if its possible to append new configuration content into the defaulted yaml configuration file without recreating it .
Currently I'm using provisioner for updating the file , but is there a way appending content to the file without changing it ?
resource "null_resource" "merge_kubeconfig" {
triggers = {
always = timestamp()
}
depends_on = [module.eks_cluster]
provisioner "local-exec" {
interpreter = ["/bin/bash", "-c"]
command = <<EOT
set -e
echo 'Applying Auth ConfigMap with kubectl...'
aws eks wait cluster-active --name '${local.cluster_name}'
aws eks update-kubeconfig --name '${local.cluster_name}' --alias '${local.cluster_name}-${var.region}' --region=${var.region}
EOT }
}Thanks in advance !
