# Dummy controller
This example contains the source code of a simple dummy controller. If you want
more details on the interface, or what the generic controller is actually doing,
please read [this doc](/docs/dev/getting-started.md). You can deploy the controller as
follows:
```console
$ kubectl create -f deployment.yaml
service "default-backend" created
deployment "dummy-ingress-controller" created
$ kubectl get po
