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

Real-world Ansible Vault Workflow


The Ansible vault implementation is a really robust solution designed to provide security for sensitive information. The implementation (as you learned already) allows us to encrypt, decrypt, rekey, and edit private data with ease. As easy as the vault is to use, finding a maintainable way to utilize the Ansible vault is not always easily apparent. As such, within this section, we will discuss some tips and tricks that can make your Ansible vault experience a bit more enjoyable.

Ansible vault with roles

The Ansible vault implementation is best leveraged in conjunction with roles. Roles (as we discussed earlier) allow us to modularize our playbooks and reuse functionality within them. The specific area of the roles implementation we are going to look at would be the vars folder. The vars folder is where we define our variables and data points that are then used by the tasks and plays.

To begin with this tutorial, let's start by creating an Ansible playbook with...
