Deploying a DNS Workload

Hey guys!

I am trying to deploy Pi-hole on my Single Node Rancher instance. I have opted to deploy the workload with a HostPort on port 53, so that I can address it directly when I set it as a default DNS server for the rest of the network.

However, as soon as I try to create a pod, deployment breaks down for the entire server because of DNS not resolving. I am of course missing something, but I have trouble seeing it.

Any help is greatly appreciated!
