Implementing DevOps with Ansible 2

By: Jonathan McAllister

Overview of this book

Thinking about adapting the DevOps culture for your organization using a very simple, yet powerful automation tool, Ansible 2? Then this book is for you! In this book, you will start with the role of Ansible in the DevOps module, which covers fundamental DevOps practices and how Ansible is leveraged by DevOps organizations to implement consistent and simplified configuration management and deployment. You will then move on to the next module, Ansible with DevOps, where you will understand Ansible fundamentals and how Ansible Playbooks can be used for simple configuration management and deployment tasks. After simpler tasks, you will move on to the third module, Ansible Syntax and Playbook Development, where you will learn advanced configuration management implementations, and use Ansible Vault to secure top-secret information in your organization. In this module, you will also learn about popular DevOps tools and the support that Ansible provides for them (MYSQL, NGINX, APACHE and so on). The last module, Scaling Ansible for the enterprise, is where you will integrate Ansible with CI and CD solutions and provision Docker containers using Ansible. By the end of the book you will have learned to use Ansible to leverage your DevOps tasks.

Summary


In this chapter, we discovered some interesting and unique ways to integrate the Ansible automation system with Docker. We learned that these two seemingly redundant technologies can be combined to provide a robust automation implementation that scales very well.

We also talked about how to inversely leverage Ansible playbook tasks to create, update, delete, and manage containers. Then, we covered how to attach and remove networking from these containers. You learned that even though these implementations might have looked difficult at first, they proved to be quite easy actually.

In the next chapter, we will take a look at how to extend Ansible and create custom modules. We will educate you on how to use Python to extend Ansible and create custom modules that integrate with unique specific technology stacks. This will be done by providing a set of tutorials that teach you how to write and release custom Ansible modules. This chapter will teach you how to read input, manage facts,...
