Learning Ansible 2.7 - Third Edition

By: Fabio Alessandro Locati

Overview of this book

Ansible is an open source automation platform that assists organizations with tasks such as application deployment, orchestration, and task automation. With the release of Ansible 2.7, even complex tasks can be handled much more easily than before. Learning Ansible 2.7 will help you take your first steps toward understanding the fundamentals and practical aspects of Ansible by introducing you to topics such as playbooks, modules, and the installation of Linux, Berkeley Software Distribution (BSD), and Windows support. In addition to this, you will focus on various testing strategies, deployment, and orchestration to build on your knowledge. The book will then help you get accustomed to features including cleaner architecture, task blocks, and playbook parsing, which can help you to streamline automation processes. Next, you will learn how to integrate Ansible with cloud platforms such as Amazon Web Services (AWS) before gaining insights into the enterprise versions of Ansible, Ansible Tower and Ansible Galaxy. This will help you to use Ansible to interact with different operating systems and improve your working efficiency. By the end of this book, you will be equipped with the Ansible skills you need to automate complex tasks for your organization.

Creating a test environment with Vagrant

To be able to learn Ansible, we will need to make quite a few playbooks and run them.

Doing this directly on your computer will be very risky. For this reason, I would suggest using virtual machines.

It's possible to create a test environment with cloud providers in a few seconds, but it is often more useful to have those machines locally. To do so, we will use Vagrant, which is a piece of software by Hashicorp that allows users to quickly set up virtual environments independently from the virtualization backend used on the local system. It does support many virtualization backends (in the Vagrant ecosystem these are known as Providers) such as Hyper-V, VirtualBox, Docker, VMWare, and libvirt. This allows you to use the same syntax no matter what operating system or environment you are in.

First we will install vagrant. On Fedora,...
