Kubelet

• The kubelet is the agent that runs on each node, and is responsible for launching pods.
• It doesn't directly run containers but instead controls a runtime, such as Docker or rkt.
• The kubelet operates at the level of PodSpec, so it only knows how to launch pods.
• The kubelet also runs a tool called cadvisor that collects metrics about resource usage on the node, and using each container that is running on the node, this information can then be used by Kubernetes when making scheduling decisions.
