Add a zone to CoreDNS

To add your own zone to the CoreDNS configuration in a cluster, use ConfigMap.

Create a manifest for ConfigMap. Specify the name coredns-custom and the namespace kube-system. The name of the file that is created through ConfigMap must end with the .custom postfix . Example manifest:
```
apiVersion: v1
kind: ConfigMap
metadata:
    name: coredns-custom
    namespace: kube-system
data:
    test.custom: |
      example.com:53 {
        whoami
      }
```

Restart the CoreDNS pods:

kubectl delete po -n kube-system -l k8s-app=kube-dns
