Worker nodes are the ones who do the work.

  1. Components of master

i)Api-server: control plane front end
ii)Cluster store: Persistent storage cluster which uses etcd.
iii)Controller manager: It has controllers which checks for changes thus helping maintain desired state.
iv)Scheduler: Gives work to nodes and watches apiserver for new pods.
