Create an admin service account in the default namespace, then register in kubeconfig and use

k8s-admin-config

# rm ~/.kube/config && eksctl utils write-kubeconfig --cluster dev
kubectl create serviceaccount admin
kubectl create clusterrolebinding admin --serviceaccount default:admin --clusterrole cluster-admin

secret_name=$(kubectl get serviceaccount admin -o jsonpath={.secrets[].name})
secret_token=$(kubectl get secret ${secret_name} -o jsonpath={.data.token} | base64 --decode)
current_cluster_name=$(kubectl config view --minify -o jsonpath={.clusters[].name})
current_cluster_endpoint=$(kubectl config view --minify -o jsonpath={.clusters[].cluster.server})

kubectl config set-credentials admin --token=${secret_token}
kubectl config set-context admin-ctx --user=admin --cluster ${current_cluster_name}
kubectl config use-context admin-ctx
