I just use unbound where I have a ansible script install it from the arch repos and deploy a handwritten config file with the dns entries. Then it forwards the rest to my DNS provider. I have my router set the address of that unbound host as the DNS server for my devices via DHCP.

I don't use k8s in my home network (though I do have some podman containers), but there's probably something with more k8s integration you can tie into your k8s ingress setup that I'm unaware of.
