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.

Basic Principles of Configuration Management


Configuration Management aims to help engineering organizations manage the infrastructure, create reusable automation, and provide a strategy for managing change within. As such, Configuration Management purports to provide the following basic principles:

  • Automate where automation is possible
  • Provide traceability within the enterprise
  • Provide developers, QA, operations, and management with a reproducible infrastructure that is managed through software-development best practices
  • Develop a strategy for how new hardware will be provisioned and configured (in an automated way)
  • Manage hardware configurations effectively and with strategy
  • Develop mechanisms that provide a self-service model for deploying infrastructure changes
  • Educate the organization on Configuration Management practices

Now that we have a basic understanding of the principles of Configuration Management, let's quickly delve into each of these principles and define them in a bit more depth...
