I wasn’t able to find much information online on how to install and use traefik in a kind cluster so decided to write a short post about how I got it working.
Basically, it requires using setting the traefik service to NodePort and the mapping the ports to the control-plane container. To force the traefik pod to run on the control-plane container [node] you have to add a node selector and toleration to the helm values file.
