New to k8s and was following the AWS documentation. All was fine until it was time to sunset what I was doing. Hope an expert here can suggest a solution.
I successfully deleted the sample namespace but i cannot delete the cluster.
$ eksctl delete cluster --name learner-1

Can't seem to find anything helpful by googling. I launched my cluster on 2 t2.micro instances. Perhaps it has insufficient resources but it didn't complain when I deployed a simple nginx service.
Thanks.
