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.

The extensible architecture that comprises Ansible was designed to support the creation of modules and expand the Ansible solution to fit the user's needs. As a result, Ansible itself and many of its now core modules derive from once available plugins.

Throughout the years, Ansible's creators added numerous API hooks and architectures in an effort to support expanding Ansible itself via a wide variety of means. The end result of this effort was a highly extensible system, which was leveraged by developers to create a significant amounts of additional core functionality. A plugin system!

Over the years, the Ansible plugin and module system have expanded out and taken a more central role in Ansible's core architecture...
