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

Ansible Modules


Ansible provides a very robust set of tools that can aid immensely in operational implementations. Common operational implementations include managing the configuration of a given system (ensuring that packages are installed, files are present, directory structures exist, and so on), provisioning a given system to meet a set of prerequisites, and more. As we discovered earlier, playbooks and their tasks help us achieve these goals by executing a set of automations against a given system.

While the knowledge we have gained can give us the basics we need to implement simple automations, we have really just barely scratched the surface of how Ansible works. Ansible integrates with hundreds of system-level tasks and thousands of external third-party solutions and can be leveraged in ways we haven't even begun to fathom. Let's peel back the layers a bit and see how we can leverage Ansible for basic Configuration Management.

Ansible provides the bulk of its task functionality through...
