What is Kubernetes?

It is also referred to as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications.
Kubernetes is software that manages many server computers and runs an outsized number of programs across those computers.

On Kubernetes, all programs run in containers in order that they will be isolated from one another , and be easy to develop and deploy.
Kubernetes eases the burden of configuring, deploying, managing, and monitoring even the largest-scale containerized applications.

It also helps IT pros manage container lifecycles and related application lifecycles, and issues including high availability and cargo balancing.
The central component of Kubernetes is the cluster. A cluster is made from many virtual or physical machines that each serve a specialized function either as a master or as a node.

Each node hosts groups of 1 or more containers (which contain your applications), and therefore the master communicates with nodes about when to make or destroy containers. At an equivalent time, it tells nodes the way to re-route traffic supported new container alignments.
