Traefik v2 in Kubernetes. fail to deploy. do not see other services

I have been trying to run traefik v2.x in minikube to check it and how it routes request to needed service. I am failing to get access to my services at all. would be good to understand what I am doing wrong.

enter image description here

How to reproduce:

  1. create 2 namespaces new-ns and new-who
  2. set namespace to be default for Ingress: kubectl config set-context --current --namespace=new-ns

All yaml files can be found in https://github.com/vencrena-LT/traefik

  1. deploy CustomResourceDefinition
  2. deploy ClusterRole , ClusterRoleBinding and ServiceAccount (to new-ns namespace)
  3. deploy DaemonSet and Service (to new-ns namespace)

then would like to deploy 2 apps: in both namespaces (for testing purposes)

  1. Deployment, Service and IngressRoute to new-ns namespace
  2. Deployment, Service and IngressRoute to new-new namespace

Dashboard: enter image description here Routes: enter image description here LocalPod: enter image description here

some logs from traefik pod:

any hints what I am doing wrong? why can not access mydomain.local and mydomain.com and see whoami services. why no routes are seen in Traefik dashboard

Your ClusterRole definition is a bit too thin:

https://github.com/vencrena-LT/traefik/blob/main/2_roles.yml

You could try to follow the example here:

https://github.com/sleighzy/k3s-traefik-v2-kubernetes-crd

For the question why no routes are seen: Traefik will pickup from k8s routes when you specify

        - --providers.kubernetescrd
        - --providers.kubernetesingress

Also please be aware of the namespace where traefik resides, you will apply IngressRoutes on that namespace
