Run the following command to join a worker node to the server nodes. We are leveraging the cluster-secret here. Since our server nodes were set up to use this, so too must any agent nodes.
```
curl -sfL https://get.k3s.io | K3S_URL=https:/<server_node>:6443 K3S_CLUSTER_SECRET='mysecret' sh -

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 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.
