KubernetesCRD UDP Service

Traefik Traefik v2
1

Hi all,
I have a VPN kubernetes service listening to UDP port 500.
Traefik itself has Entrypoint :500/udp defined (shows up on Dashboard); named udp500.
Traefik 2.4.8 with KubernetesCRD.

My Route looks as follows:

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRouteUDP
metadata:
  name: myroute
  namespace: apps
spec:
  entryPoints:
    - udp500
  routes:
  - services:
    - name: myservice
      protocol: UDP
      port: 500

Here my service:

kind: Service
apiVersion: v1
metadata:
  name: myservice
  namespace: apps
spec:
  selector:
    app: myapp
    namespace: apps
  ports:
    - protocol: UDP
      port: 500
      targetPort: 500

And the application deployment itself:

apiVersion: apps/v1 
kind: Deployment
metadata:
  name: myapp
  namespace: apps
  labels:
    app: myapp
spec:
  selector:
    matchLabels:
      app: myapp
  replicas: 1
  template:
    metadata:
      labels:
        app: myapp
        name: myapp
    spec:
      containers:
      - name: myapp
        image: containerimage
        ports:
        - name: udp500
          protocol: UDP
          containerPort: 500
        securityContext:
          privileged: true

Traefik Dashboard (UDP Routers) tells me:

the udp service "apps-myroute-0@kubernetescrd" does not exist

What is the problem here?
Many Thanks, Wolfram

hello @wopl

Do you see your UDP service exposed through the command:

kubectl get endpoints

Thanks, this helped. I had my loadbalancer service misconfigured. Still not running, but I can move forward now.
