Since you’re using Kubernetes, have you looked at external-dns? In my home lab, I use external-dns to take Ingress and Service resources and register them into my internal DNS zone. I use the etcd backend. external-dns registers zones in etcd, then CoreDNS queries from etcd. As soon as I create a new Ingress, it’s automatically registered and pointing to my Traefik service.
