Dear friend, you should first look into using Nomad or Kamal deploy instead of K8S
You mean the rugpull-stack? "Pray we do not alter the deal further when the investors really grumble" https://github.com/hashicorp/nomad/blob/v1.9.3/LICENSE
As for Kamal, I shudder to think of the hubris required to say "pfft, haproxy is for lamez, how hard can it be to make my own lb?!" https://github.com/basecamp/kamal-proxy
