This post is a tutorial on how to expose a website hosted with nginx by using the K3s built-in ingress controller “Traefik”.

It is based on my last post

• Setup Your Own Kubernetes Cluster with K3s — Take 2 — k3sup

The result of this post was an “empty” cluster without any “useful” services. In my first post on installing K3s I have created an ingress controller based on HAProxy. At that time I was not aware that K3s already comes with an ingress controller all up and running.

This time, four resources are needed

• Config Map
• Deployment
• Services
• Ingress

The config map is a quick and dirty way of making it possible for nginx to access the html-file. It is not a clean way of hosting a website and is used just for this purpose.
