Nginx Ingress Transportserver how to use globalconfig with helm charts?

Hello Everyone,

I tried to see a clear example of Transportserver and globalconfig CR but there is none.

Nginx Ingress Transportserver how to use globalconfig with helm charts as I see that the transportserver can't see the listener?

apiVersion: k8s.nginx.org/v1
kind: GlobalConfiguration
metadata:
name: nginx-ingress-controller
namespace: f5-nginx
spec:
listeners:

• name: nginx-tcp
  port: 81
  protocol: TCP

---

apiVersion: k8s.nginx.org/v1
kind: TransportServer
metadata:
name: nginx-tcp
spec:
listener:
name: nginx-tcp
protocol: TCP
upstreams:

• name: nginx-tcp
  service: hello-world-app-new-cluster
  port: 8080
  action:
  pass: nginx-tcp

I managed to make it working as I saw #1951 but how can you reference an external config map and not use values.yaml or there is no way?

helm upgrade -f nginx-values.yaml nginx-ingress oci://ghcr.io/nginx/charts/nginx-ingress
--version 2.4.1
--namespace f5-nginx
--set controller.kind=daemonset
--set controller.image.tag=5.3.1
--set controller.ingressClass.name=nginx-nginxinc
--set controller.ingressClass.create=true
--set controller.ingressClass.setAsDefaultIngress=false

controller:
enableCustomResources: true
globalConfiguration:
create: true
spec:
listeners:
- name: nginx-tcp
port: 88
protocol: TCP
