How to scale up Traefik?

In default, k3s only install one traefik instance per cluster and one servicelb(forward traffic to traefik via netfilter) per node, to scale up traefik instance:

1. configure deployment.prelicas in HelmChartConfig of Traefik, which located at services/k3s/traefik-custom-config.yaml

2. via kubectl scale --replicas x deployment -n kube-system traefik

How to scale up CoreDNS
