Docker and Kubernetes for Java Developers

Overview of this book

Imagine creating and testing Java EE applications on Apache Tomcat Server or Wildfly Application server in minutes along with deploying and managing Java applications swiftly. Sounds too good to be true? But you have a reason to cheer as such scenarios are only possible by leveraging Docker and Kubernetes. This book will start by introducing Docker and delve deep into its networking and persistent storage concepts. You will then proceed to learn how to refactor monolith application into separate services by building an application and then packaging it into Docker containers. Next, you will create an image containing Java Enterprise Application and later run it using Docker. Moving on, the book will focus on Kubernetes and its features and you will learn to deploy a Java application to Kubernetes using Maven and monitor a Java application in production. By the end of the book, you will get hands-on with some more advanced topics to further extend your knowledge about Docker and Kubernetes.

To make your container able to communicate with the outside world, whether another server or another Docker container, Docker provides different ways of configuring networking. Let's begin with the network types which are available for our containers.

Docker network types

There are three different network types Docker delivers out of the box. To list them, execute the docker network ls command:

$ docker network ls  

Docker will output the list of available networks containing the unique network identifier, its name, and a driver which powers it behind the scenes:

To have an overview of the differences between various network types, let's describe them now one by one.
