We&rsquo;re looking at the container foundation here, specifically what OpenShift adds on top of upstream Kubernetes and how Operators turn that into an extensible platform for everything else we&rsquo;ll cover.</p> <h2 id="kubernetes-is-the-engine">Kubernetes is the Engine</h2> <p>Kubernetes is the most widely adopted container orchestration system in the world, and OpenShift is built on top of it. But &ldquo;built on top of&rdquo; understates what Red Hat has done. Kubernetes is a powerful set of primitives such as a control plane, an API, a scheduler. This is the engine for managing containers on a distributed cluster. But just like your car, the engine while being maybe the most important component, won&rsquo;t get you to the grocery store alone. You still need tires, a steering wheel, brakes, and a series of other things for your car to be a useful tool. Well, organizations need more than the basic Kubernetes components to run their workloads. This includes things like authentication, observability, security controls, and a console for it to be used for production.</p>
