This post describes how to expose the kubernetes dashboard deployed in a k3s cluster via the default Traefik ingress controller. It was quite difficult to get it working, mainly because the kubernetes dashboard is by default configured for https. The way described here keeps that setup for the kubernetes dashboard.

Config
I'm using the very straight forward deployment definition for the kubernetes dashboard as explained below. I'm not using the helm chart at the moment, but the ingress definition should work as well in that scenario (maybe with some small tweaks).
Kubernetes Dashboard
This section shows my kubernetes dashboard deployment and surroundings so that the Ingress section (which links into these definitions) makes sense. The only object which is changed compared to the "original" definition is the service definition of the kubernetes dashboard, please check below.

For the Ingress definition I use Traefik specific components: ServersTransport and IngressRoute
