The kubelet is the primary node agent that runs on each node. It can register the node with the apiserver using one of the hostname( a flag to override the hostname) or a specific logic for a cloud provider. The kubelet works in terms of a PodSpec. A PodSpec is a YAML or JSON object that describes a pod. The kubelet takes a set of PodSpecs that are provided through various mechanisms (primarily through the apiserver) and ensures that the containers described in those PodSpecs are running and healthy. The kubelet does not manage containers that are not created by Kubernetes.
