Installing CoreDNS with kubeadm

In Kubernetes 1.9, CoreDNS is available as an alpha feature and may be installed by setting the CoreDNS feature gate to true during kubeadm init:

kubeadm init --feature-gates=CoreDNS=true

This installs CoreDNS instead of kube-dns.

You can configure CoreDNS to support many more use cases than kube-dns by modifying the Corefile. For more information, see the CoreDNS site.
