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.

When you go in the Projects section, in the left-hand menu bar, you'll see something like the following:

As you can see, a Demo Project is already in place (the installer created it for us!) and it is backed by a Git repository.

On the left-hand side of the project name, a white circle is present, and represents that the specific project has never been pulled. If a green circle were present, it would mean that the project has been pulled successfully. A pulsing green circle means that a pull is in progress, while a red stop sign means that something went wrong.

In the same line of the project, there are three buttons:
