The Kubernetes DNS addons, kube-dns, has been replaced with CoreDNS.
This change is made in accordance with Kubernetes making CoreDNS the official default
starting from
<link xlink:href="https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.11.md#sig-cluster-lifecycle">Kubernetes v1.11</link>.
Please beware that upgrading DNS-addon on existing clusters might induce
minor downtime while the DNS-addon terminates and re-initializes.
Also note that the DNS-service now runs with 2 pod replicas by default.
The desired number of replicas can be configured using:
<option>services.kubernetes.addons.dns.replicas</option>.
