Kubernetes Without kube-proxy, AWS ENI, and dedicated etcd cluster for Cilium. This guide will just go through a basic setup. Prerequisites aws cli [https://aws.amazon.com/cli/] kubectl [https://kubernetes information on the configuration options kops offers. See the kops cluster spec documentation [https://pkg.go.dev/k8s.io/kops/pkg/apis/kops? tab=doc#CiliumNetworkingSpec] for a comprehensive list of all the options a Kubernetes cluster and install Cilium. If in doubt, pick the minikube route, you will be good to go in less than 5 minutes. Deploy the Demo Application Now that we have Cilium deployed and kube-dns
