A `node` is a worker machine in Kubernetes, previously known as a `minion`. A node
may be a VM or physical machine, depending on the cluster. Each node has

components. The services on a node include Docker, kubelet and kube-proxy. See
components. The services on a node include the [container runtime](/docs/concepts/overview/components/#node-components), kubelet and kube-proxy. See
