+For details on how to deploy all these examples, please refer to chapter 14 in Ansible for DevOps. One quick example you can test locally:
+
+  1. cd into the 'examples' directory, and run the `k8s-module.yml` playbook, which creates an Nginx deployment and service on the cluster: `ansible-playbook -i ../inventory k8s-module.yml`
+  2. Copy the nodePort from the final task output in that playbook; this is the port on which Nginx is accessible.
+  3. Open your browser and access [http://cluster.k8s.test:32474/](http://cluster.k8s.test:32474/) (assuming nodePort is `32474`).
