Scheduler - assigns pods to nodes Api server - communicates to controller &amp; scheduler etcd - key value store used asfor all cluster data</li> </ul> <ol> <li>Worker node comprises Pods - smallest unit representing an instance . May contain 1 or more container. Kubelet - creates, destroys, updates container nodes Proxy - manages network across nodes.</li> </ol> <ul> <li>What is POD, write a 10 lines explaination on POD</li> </ul> <p>POD is the smallest deployable unit in K8s.<br> Can contain 1 or more containers.<br> single instance running process in a cluster.</p>
