This book on Kubernetes, the  container cluster manager, discusses all aspects of using Kubernetes in today's complex big data and enterprise applications, including Docker containers.
Starting with installing Kubernetes on a single node, the book introduces Kubernetes with a simple Hello example and discusses using environment variables in Kubernetes. 
Next, the book discusses using Kubernetes with all major groups of technologies such as relational databases, NoSQL databases, and in the Apache Hadoop ecosystem.
The book concludes with using multi container Pods and installing Kubernetes on a multi node cluster. No other book on using Kubernetes - beyond simple introduction - is available in the market.

What You Will LearnHow to install Kubernetes on a single node
How to install Kubernetes on a multi-node cluster
How to set environment variables
How to create a multi-container pods using Docker
How to use volumes
How to use Kubernetes with Apache Hadoop Ecosystem
How to use Kubernetes with NoSQL Databases
How to use Kubernetes with RDBMS
Who This Book Is ForApplication Developers including Apache Hadoop Developers, Database developers and NoSQL Developers.
