Learn enough Golang and hack on CoreDNS

Description

I'm implementing a split-horizon DNS for my home Kubernetes cluster to be able to access my internal (and external) services over the local network through public domains. I managed to make a PoC with the k8s_gateway plugin for CoreDNS. However, I soon found out it responds with IPs for all Gateways assigned to HTTPRoutes, publishing public IPs as well as the internal Loadbalancer ones.

To remedy this issue, a simple filtering mechanism has to be implemented.

Goals

  • Learn an acceptable amount of Golang
  • Implement GatewayClass (and IngressClass) filtering for k8s_gateway
  • Deploy on homelab cluster
  • Profit?

Resources

EDIT: Feature mostly complete. An unfinished PR lies here. Successfully tested working on homelab cluster.

        Sorry, unfortunately, I already managed to finish most of the task and created a PR. Didn't take that much work as I thought.
