Why do we need it??
Kubernetes usually resolve the problem which usually encountered in Docker like scalability, Load balancing, Self heal etc. It provide single view for cluster management which in turn may have 1000 of node, pod or containers.
How it work?
There are two parts.
1) Master Node:- Master node controls the worker node or pod by its component like API server, controller, scheduler, storage. Master node monitored the worker node and its work. If any node/pod failed it will immediately create new pod as per scheduler.
2) Worker Node:- usually request the membership of master, once registered it will allocated the task by master node (more specific by scheduler)
