Heavy performance impact when using traefik on kubernetes

I'm happy to try, but using the instructions in this blog post, I'm not able to install it. Could you point me to instructions as to how to install it directly? The rancher version installs seamlessly.

BTW: compared to the nginx ingress controller, your instructions are much harder to follow. I've also tried downloading the helm chart, but I'm getting a mess of errors. For example:

$ helm install traefik traefik/traefik
Error: INSTALLATION FAILED: failed to install CRD crds/ingressroute.yaml: unable to recognize "": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1beta1"

I'm using k3s with k8s 1.23. Is your helm chart my only options, or do you have a simpler yaml based install procedure?
