How kubernetes works?

Kubernetes clusters are comprised of one master node(control plane) and a number of worker nodes. These nodes can either be physical computers or virtual machines, depending on the cluster. The master node controls the state of the cluster; for example, which applications are running and their corresponding container images.

Components of Master Node:

API Server – front end of the kubernetes

Control store etcd – stores the cluster data

Controller manager – controls node, endpoint and pods

Controller scheduler – watches the pods and assigns to node

Components of Worker Node:

Kubelet – Instantiates POD.

Kube proxy -kube-proxy maintains network rules on nodes/ Iptables

Controller runtime /Docker engine – POD – container creation

Components of Workstation

Kubectl – CLI to interact with APIserver
