Simple script to create a KinD cluster ready for Gateway API conformance test

Remember to:

• Change the address on metallb IPAddressPool to the right range
• Bump versions as required

Call it with: ./gw-conformance.sh BACKEND

being backend:

rikatz

package main

import (
	"encoding/json"
	"fmt"

	crossplane "github.com/nginxinc/nginx-go-crossplane"
)

func main() {

rikatz

For the default backend, apparently it is using proxy_protocol. Proxy is not implemented yet, as NGINX does not support setting proxy using a variable.

Probably need to create 2 segregated internal listeners, one with proxy and one without it.

Maybe, if I can already pass inside what backend should be used (a dynamic variable with the script loaded globally? otherwise will have to query the shared map twice)
