Overview of this book

DevOps is a practical field that focuses on delivering business value as efficiently as possible. DevOps encompasses all the flows from code through testing environments to production environments. It stresses the cooperation between different roles, and how they can work together more closely, as the roots of the word imply—Development and Operations. After a quick refresher to DevOps and continuous delivery, we quickly move on to looking at how DevOps affects architecture. You'll create a sample enterprise Java application that you’ll continue to work with through the remaining chapters. Following this, we explore various code storage and build server options. You will then learn how to perform code testing with a few tools and deploy your test successfully. Next, you will learn how to monitor code for any anomalies and make sure it’s running properly. Finally, you will discover how to handle logs and keep track of the issues that affect processes

Docker intermission


In Chapter 7, Deploying the Code, we will have a look at a new and exciting way to package our applications, called Docker.

In this chapter, we have a similar challenge to solve. We need to be able to try out a couple of different Git server implementations to see which one suits our organization best.

We can use Docker for this, so we will take this opportunity to peek at the possibilities of simplified deployments that Docker offers us.

Since we are going to delve deeper into Docker further along, we will cheat a bit in this chapter and claim that Docker is used to download and run software. While this description isn't entirely untrue, Docker is much more than that. To get started with Docker, follow these steps:

  1. To begin with, install Docker according to the particular instructions for your operating system. For Red Hat derivatives, it's a simple dnf install docker-io command.

    Note

    The io suffix might seem a bit mysterious, but there was already a Docker package that implemented...
