<p>This tutorial describes how to setup ExternalDNS for usage within a <a href="https://github.com/kubernetes/minikube">minikube</a> cluster that makes use of <a href="https://github.com/coredns/coredns">CoreDNS</a> and <a href="https://github.com/kubernetes/ingress-nginx">nginx ingress controller</a>.<br />
You need to:<br />
* install CoreDNS with <a href="https://github.com/etcd-io/etcd">etcd</a> enabled<br />
* install external-dns with coredns as a provider<br />
* enable ingress controller for the minikube cluster</p>
