I currently want to make the service to be exposed so that 80 -> 443 -> https automatically with TLS Termination at Gateway level. However I couldn't able to do anything with config-networking, config-gateway, config-domain.

I was able to make it work with http-80 though the HTTPRoute generated are only using 80. I want to be able to generate using this format:
