We will create a Custom Resource Definition (CRD) for a simple <code>Website</code> resource. The goal of our controller will be to watch for these <code>Website</code> resources and, for each one, create a corresponding Kubernetes <code>Deployment</code> and <code>Service</code>.</p> <p>This is a powerful pattern that allows you to extend the Kubernetes API to manage your own applications declaratively.</p>
