How do we add in real_ip_header: X-Forwarded-For for our gateways?

Questions

Hi, I am a rookie still learning and hoping to get some guidance.

We are using kong db-less gateways to route traffic. I am trying to figure out how to add in some additional configurations like

real_ip_header: X-Forwarded-For
real_ip_recursive: “on”
trusted_ips:

but I am not sure where to add these.

are these added to the Kong Gateway definition? Does this go into the proxy definition?

currently we have gateways set like this

apiVersion: gateway.networking.k8s.io/v1
kind: Gateway
metadata:
  name: kong
spec:
  gatewayClassName: kong
  listeners:
   - name: https
     port: 443
     protocol: HTTPS
     hostname: "*.domain.com"
     tls:
       mode: Terminate
       certificateRefs:
         - kind: Secret
           name: wildcardcert

Would we define the gateway like this?

apiVersion: gateway.networking.k8s.io/v1
kind: Gateway
metadata:
  name: kong
spec:
  gatewayClassName: kong
  -env:
   - name:  REAL_IP_HEADER
     value: X-Forwarded-For
   - name: KONG_TRUSTED_IPS
     value: 0.0.0.0/0,::/0
   - name: KONG_REAL_IP_RECURSIVE
     value: "on"
  listeners:
   - name: https
     port: 443
     protocol: HTTPS
     hostname: "*.domain.com"
     tls:
       mode: Terminate
       certificateRefs:
         - kind: Secret
           name: wildcardcert

thanks in advance

OK i think I have determined that these config env changes like real_ip_header and real_ip_recursive would go in the deployment.

Now i need to find out where the default values.yaml file is when running

helm install kong kong/ingress -n kong --create-namespace
