*Each kubernetes Components & write 2-3 lines about each one of them

kubelet: It is a software agent that runs continuously on every node of the cluster. The kubelet ensures that the containers run in Pods in a healthy manner

docker -for holding the containers with libraries and files necessary for software

kubectl-kubectl is your cockpit to control Kubernetes. It allows you to perform every possible Kubernetes operation .it is client for kubernetes api

kubeadm-Kubeadm is a tool built to provide best-practice fast paths for creating Kubernetes clusters.It performs the actions necessary to get a minimum viable, secure cluster up and running in a user friendly way

kube proxy-It maintains the networking rules and protocols on the nodes. It is a network proxy that runs on each node in the cluster to ensure seamless and secure networking

Network Driver-used for networking driver

Controller mgmr-it embeds core control loops shipped with kuernetes.controllers help to watch loops in which state cluster is ,then make or request change

Schedular-in which assigns pods to nodes .these determine which nodes are valid placements for each pod

Etcd-it stores all its data its configuration and states along with metadatait also stores api objects and service discovery

API Server-it validates and configures data for api objects including services ,replication controllers etc.these provide rest operations
