What I miss from all of these tutorials is one very important piece - how to handle network routing and dns automation within your home network, that's in typical scenario is being handled by the ingress/cloud controller. Without having automated (or easy enough) way of reaching the apps you're deploying there, each of these clusters is pretty much useless for users except for maybe learning basics of k8s, what's easier done with minikube.

I then have external-dns running (https://github.com/kubernetes-sigs/external-dns) which manages the relevant A/CNAME records on Google DNS (other DNS providers are supported) so that I can resolve "myservice.mydomain.com" to the service's IP address.

I wrote a bit about the BGP bit last year: https://www.growse.com/2019/04/13/at-home-with-kubernetes-me...

Admittedly, I have no desire to expose any of these service to the internet, but if I did I could use an IPv6 address on the service instead, or add a static NAT rule to the router to forward traffic to the service IPv4 address. Auto provisioning of NAT rules feels icky, so I'd probably go down the ipv6 route if I wanted to do this.
