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.

Summary


In this chapter, we discussed the various architecture types that Ansible provides, we talked about how inventory files work, and how to target specific groups and servers using the -l command. We also talked about how to install, set up, and configure Ansible to work under most common conditions. In our examples we look at a lot of Ubuntu specific implementations but the conversion to other OS's should be easy.

In the next chapter, we will learn all about playbook files and inventory file extensibility as well as how to create additional inventory files to help manage your infrastructure more effectively. Playbook's represent the heart and soul of the Ansible platform and instruct it on how to behave on a given server or infrastructure.

By the time we complete the next chapter, we should begin to have the skills you will need to write a playbook and execute it against one of a few machines. In addition, you should be able to perform most basic Configuration Management and deployment...
