Kubernetes Node

A Kubernetes Node is a logical collection of IT resources that supports one or more containers. Nodes contain the necessary services to run Pods (which are Kubernetes's units of containers), communicate with master components, configure networking and run assigned workloads. A Node can host one or multiple Pods. Each Kubernetes Node has services to create the runtime environment and support Pods. These components include Docker, kube-proxy and kubelet.
