Running Istio on AWS with Kops

One oversight offhand is the installation of kubectl v1.13.0. Kops currently only installs v1.11 Kubernetes.

From https://kubernetes.io/docs/tasks/tools/install-kubectl/

You must use a kubectl version that is within one minor version difference of your cluster. For example, a v1.2 client should work with v1.1, v1.2, and v1.3 master.
