UDP Service dosent seem to work when multiports are defined.

[kakarotbyte]

I have been following the Doc and noticed that when I create a UDP service with multiple ports it dosent seem to work....

example:

kubectl get cm udp-services tcp-services -o yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: udp-services
  namespace: ingress-nginx
data:
  "5555": ingress-nginx/udp-echo-server:33333
  "6666": ingress-nginx/udp-echo-server2:11111

My ingress args

containers:
- args:
  - /nginx-ingress-controller
  - --publish-service=$(POD_NAMESPACE)/ingress-nginx-controller
  - --election-id=ingress-controller-leader
  - --controller-class=k8s.io/ingress-nginx
  - --ingress-class=nginx
  - --configmap=$(POD_NAMESPACE)/ingress-nginx-controller
  - --validating-webhook=:8443
  - --validating-webhook-certificate=/usr/local/certificates/cert
  - --validating-webhook-key=/usr/local/certificates/key
  - --tcp-services-configmap=ingress-nginx/tcp-services
  - --udp-services-configmap=ingress-nginx/udp-services

Ports running within the ingress container:

nsenter -t 11056 -n netstat -plntu

Ask:

• When I tested the same with TCP i was able to see multiple ports open.... but for udp it don't work. How can we make it work?

Update:

When I add a service from a different namespace it seems to work. I am assuming if we try to put multiple services from same namespace it wont work.

/remove-kind bug

Need to check but I think the name pairs with one port

The TCP/UDP feature is being deprecated #11666 .

So closing this issue as it will not be worked upon.
