## Ingress Controller
The default Ingress Controller is NGINX and is deployed as a DaemonSet in the `ingress-nginx` namespace. The pods are only scheduled to nodes with the `worker` role.
The default Ingress Controller is Traefik and is deployed as a DaemonSet in the `traefik` namespace. The pods are only scheduled to nodes with the `worker` role.
Check if the pods are running on all nodes:
```
kubectl -n ingress-nginx get pods -o wide
kubectl -n traefik get pods -o wide
```
Example output:
```
kubectl -n ingress-nginx get pods -o wide
