in the previous section we discussed the services running on the Kubernetes architecture Master,This section discusses node nodes. Node is where the Pod runs, Kubernetes supports Docker, Rkt, and other container runtime. The Kubernetes components running on node have Kubelet, Kube-proxy, and Pod networks (such as flannel).KubeletKubelet is the agent of node, and
