A Deployment is the controller most stateless applications run under: you declare how many Pods you want and what they look like, and Kubernetes keeps that many running and replaces them gradually when the template changes. Seeing the ReplicaSets and Pods appear and change shows you what the controller does on your behalf.</p>
