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

The Ansible Architecture


Ansible was created with an incredibly flexible and scalable automation engine. It allows users to leverage it in many diverse ways and can be adapted to be used in the way that best suits your specific needs. Since Ansible is agentless (meaning there is no permanently running daemon on the systems it manages or executes from), it can be used locally to control a single system (without any network connectivity) or leveraged to orchestrate and execute automation against many systems, via a control server.

In addition to the aforementioned architectures, Ansible can also be leveraged via Vagrant or Docker to provision infrastructure automatically. This type of solution basically allows Ansible users to bootstrap their hardware or infrastructure provisioning by running one or more Ansible playbooks.

Note

If you happen to be a Vagrant user, there are instructions within the HashiCorp Ansible provisioning located at the following URL: https://www.vagrantup.com/docs/provisioning...
