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

Configuring Ansible


Ansible maintains a central configuration file, which is used to instruct Ansible on how to behave. Ansible's primary configuration file should be located (for most Linux distributions) at the following location:

 /etc/ansible/ansible.cfg 

This configuration file instructs Ansible on how to behave at runtime. During the pre-startup sequences of Ansible's execution, the configuration file is loaded into memory and sets a number of environmental flags. These flags and configuration options can help you customize the Ansible runtime. The following configuration is a snapshot of the ansible.cfg file.

Note

Nearly all Ansible configuration options can be overridden via modifications in a playbook. Changes to this configuration file will give you the ability to set base functionality/configuration.

The Ansible configuration file has a pretty detailed set of documentation items associated with each configurable option available. As such, it would be redundant to provide a complete...
