Hi,

I have setup rancher with rke2 cluster on premise on bare metal. When I deploy ingresses and services I want to reach them from outside the cluster via dns name.

Our datacenter can forward dns requests for the kubernetes subdomain to a dns server which runs inside kubernetes.

What is best practice to easily achieve this? Can you point to a tutorial?`

Thanks, Andreas

I can not tell what the best practice is but I can tell you what we did. We forwarded the port 53 to the coredns on kubernetes. Then we created on the main dns zone a delegated sub-zone with the name [kube.client.com](http://kube.client.com). Then we added the the coredns plugin [k8s\_external](https://coredns.io/plugins/k8s_external/) with the config line

```auto
k8s_external kube.client.com

```

And then we created the service objects as described on the link. You will then get service dns names which look like this: [servicename.servicenamespace.kube.client.com](http://servicename.servicenamespace.kube.client.com)
