Ingress for non http(s) services tcp-services-configmap for external tcp port mapping to services not working/missconfigured?

Hi,

I noticed that the nginx-ingress controllers have the “tcp-services-configmap” enabled though for some reason after applying a basic configmap for my NS I dont see these ports open or cant use the port.

CM:

apiVersion: v1
kind: ConfigMap
metadata:
name: tcp-configmap-example
data:
9000: “test-ns/service-mqtt-ca:9883”

cmd:
kubectl create -f -n test-ns

try access port 9000 on the cluster fails

reference link: https://github.com/kubernetes/ingress-nginx/blob/master/docs/user-guide/exposing-tcp-udp-services.md

any assistance much appreciated.

Thanks,
