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.

Networking commands

The parent command for managing networks in Docker is docker network. You can list the whole command set using the docker network help command, as you can see in the following screenshot:

To have a detailed syntax and description of each option available for a specific command, use the -help switch for each of the commands. For example, to get the description of parameters available for docker network create, execute the docker network create -help.

Let's briefly describe each command available:

  • $ docker network ls: This is the command we have been using previously, it simply lists networks available for your containers. It will output the network identifier, its name, the driver being used, and a scope of the network
  • $ docker network create: Creates new network. The full syntax of the command is, docker network create [OPTIONS] NETWORK. We will use...
