Scaling integration pod and the replicas are not able to receive traffic via UDP port

[haifzhan]

Hi Apache Camel team:

Situation:

1. I have an integration pod is listening on UDP 8444 and forward it to 30006, and it is configured in my-integration-service.yaml
2. I am trying to scale the integration followed the document CAMEL K INTEGRATION SCALING
   

For instance I have 2 pods running after scale and only the first pod is capable of receiving incoming events.

I see a similar question under Issues scaling out camel-k integrations are not working correctly #1806. The service was enabled as a node port. As far as I know, the service trait only works for TCP not UDP.

Please help.

my-integration-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: my-integration
spec:
  type: NodePort
  selector:
    camel.apache.org/integration: my-integration
  ports:
    - protocol: UDP
      port: 8444
      targetPort: 8444
      nodePort: 30006

Some updates:
I killed the pod which is capable of receiving events when there's traffic and observed that the replica start receiving events. Now it turns out the settings are working properly.

What am I supposed to modify to make the traffic policy round robin?
