In previous parts of this series, we built the cluster from scratch: prepared the environment (Part 1), installed containerd and Kubernetes (Part 2), initialized the control-plane (Part 3), and joined the workers (Part 4). With the cluster up and all nodes in Ready state, it's time to actually put it to work: let's deploy our first application.

First, create a directory to organize this deployment's manifests:
mkdir nginx
