Configuration of static host entries in CoreDNS

Static host entries can be created for NETWAYS Managed Kubernetes in CoreDNS.

To do this, you need to create the ConfigMap coredns-extra-hosts in the kube-system namespace. This can be done, for example, via kubectl.

An example ConfigMap could look like this:

apiVersion: v1
kind: ConfigMap
metadata:
  namespace: kube-system
  name: coredns-extra-hosts
data:
  hosts.list: |
    192.168.100.100 example.com

For this you need the appropriate permissions in the cluster.
