How to use k3s coredns as the provider?

[kferrone]

I have a homelab with k3s. External dns works with core dns. I figure why not use that as my internal dns for my homelab. Now days, it's not even too hard to expose dns with a Service LB with metal-lb or kube-vip.

Just wondering if anyone has been daring enough to try this?

I figure it would involve adding a zone to the configuration and somehow only exposing that zone so I don't expose the whole internal service network to my whole network.

Also seems I would have to expose the etcd under the cluster which is installed by k3s. However, I don't know much about etcd, for example can I even have multiple "databases" like mysql?

Maybe I just end up installing an etcd in my cluster and a separate coredns. But if I have to do that, well . . . I already got some BIND laying around and that's another questionable battle with external dns.

Any ideas on what else I would have to do. Like I'm confident enough to give it a shot but there are a ton of unknowns here and this sounds like tedious trial and error unless there is at least some guidance if any.
