Think about it, you pass a YAML file to the API server and magically stuff happens. Not only that, but when disaster strikes (e.g. pod crashes) Kubernetes also makes it right again so that it matches the desired state.</p> <p>The mechanism that allows for Kubernetes to enforce this desired state is the control loop. The basics of this are pretty simple. A control loop can be though of in three stages.</p>
