Introduction

Kubernetes is very much getting lots of love and mind share these days. Here is how kubernetes.io defines the technology:

Kubernetes (K8s) is an open-source system for automating deployment, scaling, and management of containerized applications.

But what does it exactly mean? It is certainly not an easy technology to pick up and it really helps to understand the concepts behind its design and implementation.

This guide is an attempt to explain the concepts in an easy to understand and incremental fashion. I do assume that the reader is reasonably familiar with Docker and container concepts though I give a high level overview in the first two chapters.

Also, all the examples and descriptions in the guide use Linux as that is the operating system I am most comfortable with.
