One of the key mechanisms that enables this is the Controller.</p> <p>Controllers continuously monitor the cluster and ensure that the actual state matches the desired state. If something goes wrong, Kubernetes automatically corrects it.</p> <p>This behavior is commonly referred to as self-healing.</p> <p>It performs three main tasks:</p> <ul> <li>Observe the current state</li> <li>Compare it with the desired state</li> <li>Take action if they differ</li> </ul> <p>This loop runs continuously inside the Kubernetes control plane.</p>
