Enable the Dashboard
The dashboard is not enabled in the base k3s distribution. Enable the dashboard by editing the traefik.yaml manifest at
sudo vi /var/lib/rancher/k3s/server/manifests/traefik.yaml
Add the line
dashboard.enabled: "true" in the spec: set: section. Remember this is YAML so match the indent of the previous line.
Save the file and k3s will deploy the dashboard service, you can see the service with the kubectl get service command:
kubectl get service --all-namespaces NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE default kubernetes ClusterIP 10.43.0.1 <none> 443/TCP 3d5h kube-system kube-dns ClusterIP 10.43.0.10 <none> 53/UDP,53/TCP,9153/TCP 3d5h kube-system metrics-server ClusterIP 10.43.60.8 <none> 443/TCP 3d5h kube-system traefik-prometheus ClusterIP 10.43.215.249 <none> 9100/TCP 3d5h kube-system traefik LoadBalancer 10.43.204.45 192.168.1.109 80:31930/TCP,443:32219/TCP 3d5h kube-system traefik-dashboard ClusterIP 10.43.72.66 <none> 80/TCP 103m
Note the CLUSTER-IP address, if you can open a web browser on your master node, just navigate to that address. I have a headless master node so I do a reverse ssh proxy to my mac so I can access the dashboard there. To set up the reverse proxy, note the CLUSTER-IP address of the traefik-dashboard service and use it in this command line (it will different if you use a different cluster CIDR for your network). You need to set up remote login on your mac or equivalent machine to make this work.
sudo ssh -R 8080:<CLUSTER-IP>:80 user@mac
On your external box, navigate to
http:\\localhost:8080\dashboard\ and you will see the Traefik dashboard.
