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.

We've now got a framework for you and your team to learn and start developing Ansible playbooks. Consider this a similar process to learning how to drive a car from your driving-school instructor. You start by learning how to control the car with the steering wheel, then you slowly begin to control the brakes, and finally, you start maneuvering the gears, and hence, the speed of your car. Once you've done this over a period of time, with more and more practice on different kinds of roads (such as flat, hilly, muddy, potholed, and so on) and by driving different cars, you gain expertise, fluency, speed, and, basically, enjoy the overall experience...
