Definition

The kubelet is a critical component of Kubernetes, responsible for managing the lifecycle of containers on a node. It ensures that containers are running in a Pod as expected by communicating with the Kubernetes API server. The kubelet monitors the state of the Pods and reports back to the control plane, while also handling the execution of container runtime operations.
