I am struggling to get my metrics exposed on Kubernetes with Traefik 2.3.2. This is the CRD configuration I am using:

      containers:
        - name: traefik
          image: 'traefik:v2.3'
          args:
            - --api
            - --api.dashboard
            - --entrypoints.dashboard
            - --accesslog=true
            - --entrypoints.web.Address=:80
            - --entrypoints.websecure.Address=:443
            - --providers.kubernetescrd
            - --providers.kubernetesingress
            - --metrics.prometheus=true
            - --metrics.prometheus.buckets=0.100000, 0.300000, 1.200000, 5.000000
            - --metrics.prometheus.addEntryPointsLabels=true
            - --metrics.prometheus.addServicesLabels=true
            - --entryPoints.metrics.address=:8080
            - --metrics.prometheus.entryPoint=metrics
          ports:
            - name: web
              containerPort: 80
              protocol: TCP
            - name: websecure
              containerPort: 443
              protocol: TCP
            - name: metrics
              containerPort: 8080
              protocol: TCP

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: metrics
  namespace: traefik-controller
spec:
  entryPoints:
    - metrics
  routes:
    - match: Host(`traefik.mydomain.net`) && PathPrefix(`/metrics`)
      kind: Rule
      services:
        - name: prometheus@internal
          kind: TraefikService

I am trying to access the metrics at http://traefik.mydomain.net:8080/metrics but I am getting an empty response back.

Any suggestion as to what I am missing?

I tried adding - '--metrics.prometheus.manualRouting=true' to the DaemonSet configuration, but that did not make any difference (and is only required if I was to use redirects on the /metrics endpoint if I understand correctly).

I am also interested by the answer: did you find a workaround ? I also created a post with details of my problem: Can you help me getting traefik metrics ? (version 2.2.8)
