Is there a way to troubleshoot a traefix ingress route as I got an error 
http 404
? I can access the service using 
kubectl port-foward
and address 
<http://localhost:7007/catalog>

So what does your Ingress Manifest look like? Try looking at the traefik logs with "kubectl --namespace kube-system logs -l app=traefik"

Nothing appears within the log of traefix. I will try to make another test later as currently I edited manually an ingress resource which is working using 
ingress-nginx
and where I changed the ingressClass and added 
<http://traefik.ingress.kubernetes.io/router.entrypoints|traefik.ingress.kubernetes.io/router.entrypoints>: web

Try the following steps just to verify that the traefik is working correctly: 
kubectl create namespace nginx
# create a deployment
kubectl --namespace nginx create deployment nginx --image=nginx
# now create a service
kubectl --namespace nginx expose deployment nginx --port=80 --target-port=80 --name nginx
# now create the ingress
kubectl --namespace nginx create ingress nginx --rule="nginx.localhost/=nginx:80"
Then open your browser (chrome) with the URL http://nginx.localhost or use curl -H "Host: nginx.localhost" http://localhost

That should work as I documented what you proposed here: https://github.com/rancher-sandbox/rancher-desktop/issues/2460 😉

For Windows/WSL you would have to modify the way you extract the IP Address because there is no node with the name "lima-rancher-desktop" if you use the following snippet it should work on Mac/WSL/Linux: 
IP=$(kubectl get node -l <http://node.kubernetes.io/instance-type=k3s|node.kubernetes.io/instance-type=k3s> -o json | jq -r '.items[0].status.addresses[] | select(.type=="InternalIP").address')

you should find some log entries: 
kubectl -n kube-system logs -l app=traefik
Copy code
{"level":"info","msg":"Updated status on ingress nginx/nginx","time":"2022-07-05T14:53:25Z"}
{"level":"info","msg":"Server configuration reloaded on :443","time":"2022-07-05T14:53:25Z"}

I can access the resource using the nginx example
correct label is 
<http://app.kubernetes.io/instance|app.kubernetes.io/instance>: traefik

OK, then maybe you should discard the "ingressClassName" and the annotations an try again

07/05/2022, 3:51 PM
Yes. Will do that
That works without the annotation. Many thanks for your help

This is nevertheless strange that I cannot see logs of the traefix controler

if i do a 
kubectl -n kube-system get pods --show-labels
i get this:
Copy code
NAME                                      READY   STATUS      RESTARTS   AGE   LABELS
...
traefik-799bbc5bd6-8gktn                  1/1     Running     8          35d   app=traefik,chart=traefik-1.81.001,grafzahl=counted,heritage=Helm,pod-template-hash=799bbc5bd6,release=traefik
Maybe you have a typo in the used label, i do not have a label with 
<http://app.kubernetes.io/instance=traefik|app.kubernetes.io/instance=traefik>
i'm running Kubernetes v1.20.15+k3s1, that could be the difference

I restarted 
r-d
and now I can see the logs. Maybe I don have enough memory/cpu on my mac to run the r-d VM
