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.

Preface

Setting Up the Ansible Module Development Environment


In this section, we will discuss how to set up a local Linux environment for Ansible module development. In our specific implementation, we will look at how to do this in Ubuntu. However, the same set of configuration options should work under other Linux flavors as well. As new Ansible module developers, we will want to begin by understanding how to configure our system to best support Ansible development, how to setup the modules path, and how to configure the environment for testing.

The first step to getting a development environment up and running is to understand the Ansible library path on the system. This path is where Ansible will search for additional libraries. The default value for the library path is defined within the primary Ansible configuration file (/etc/ansible/ansible.cfg). The line item is shown as follows:

library = /usr/share/ansible

While the default path is defined within the Ansible configuration file, it can be...
