I was just wondering the same thing, since we use linkerd in production to handle thrift traffic to, from, and within our k8s clusters. But this statement from the examples page put me off a little: "If you use GKE, please ensure your cluster has at least 4 standard GKE nodes."

That suggestion is based on the requirements of the underlying bookinfo sample application and is not related to Istio itself.

Thanks for the clarification!
