 Now, let's make our own Docker image, push it, and start it in a Pod!
+Here's an example Dockerfile that runs a tiny Perl-based webserver that always responds with its own hostname:
+<pre>
+$ cat Dockerfile
+FROM ubuntu:bionic
+RUN apt-get update \
+ && apt-get install -y libmojolicious-perl \
+ && rm -rf /var/lib/apt/lists/*
+# Normally, you'd use COPY here, but I wanted to keep this in one file
+RUN echo "#!/usr/bin/env perl"                       >>/app.pl \
+ && echo "use Mojolicious::Lite;"                    >>/app.pl \
+ && echo "get '/' => sub {"                          >>/app.pl \
+ && echo "  shift->render(text => 'Hello World!'); " >>/app.pl \
+ && echo "};"                                        >>/app.pl \
+ && echo "app->start;"                               >>/app.pl \
+ && chmod +x /app.pl
+EXPOSE 3000
+CMD ["/app.pl", "daemon", "-l"]
+$ docker build -t kuberegistry.sjorsgielen.nl/helloworld:latest .
+$ docker push kuberegistry.sjorsgielen.nl/helloworld:latest
+</pre>
+At this point, you should be able to write a Deployment, Service and Ingress for this application, using the examples above. <code>kubectl apply</code> should then start the Pod, Traefik should route the service and whatever host/path you configured should quickly be reachable and respond with "Hello World". We've created our own image and ran it on your cluster!
