Traefik Ingress Controller
--------------------------
Traefik is deployed by default when starting the server; to disable it, start the server with the `--no-deploy traefik` option. The default config file is found in `/var/lib/rancher/k3s/server/manifests/traefik.yaml` and any changes made to this file will automatically be deployed to Kubernetes in a manner similar to `kubectl apply`.

The default config file is found in `/var/lib/rancher/k3s/server/manifests/traefik.yaml` and any changes made to this file will automatically be deployed to Kubernetes in a manner similar to `kubectl apply`.
The Traefik ingress controller will use ports 80, 443, and 8080 on the host (i.e. these will not be usable for HostPort or NodePort).
You can tweak traefik to meet your needs by setting options in the traefik.yaml file.
Reference the official [Traefik for Helm Configuration Parameters](https://github.com/helm/charts/tree/master/stable/traefik#configuration) readme for more information.
To disable it, start each server with the `--no-deploy traefik` option.
