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.

Introducing Jinja


Jinja is a templating engine that was developed in 2008 by Armin Ronacher in an effort to provide Python developers with a framework that would supply comprehensive Python-like syntax that could be used within strings and data documents. The solution was designed with similar solutions such as Smarty and Django in mind. Jinja executes its template translations in a sandbox (isolated from the rest of the program execution) so as to prevent the template engine from interfering with the normal operational execution of the Python program.

Jinja2 represents the second major version of the Jinja Python library. Jinja is leveraged to generate string-based documents based on one or more predefined templates (also made of strings). As of the writing of this book, Jinja is in use by numerous open source solutions that are actively developed with Python. Some notable examples of solutions that use Jinja include Salt, Flask, and Ansible.

When coupled with Ansible and YAML, Jinja adds...
