Ansible is a simple, but powerful, server and configuration management tool. Learn to use Ansible effectively, whether you manage one server—or thousands.

Ansible is a simple, but powerful, server and configuration management tool (with a few other tricks up its sleeve). This book helps those familiar with the command line and basic shell scripting start using Ansible to provision and manage anywhere from one to thousands of servers.

The book begins with fundamentals, like installing Ansible, setting up a basic inventory file, and basic concepts, then guides you through Ansible's many uses, including ad-hoc commands, basic and advanced playbooks, application deployments, multiple-provider server provisioning, and even Docker orchestration! Everything is explained with pertinent real-world examples, often using Vagrant-managed virtual machines.

Ansible aims to be:
- Clear - Ansible uses a simple syntax (YAML) and is easy for anyone (developers, sysadmins, managers) to understand. APIs are simple and sensible.
- Fast - Fast to learn, fast to set up—especially considering you don’t need to install extra agents or daemons on all your servers!
- Complete - Ansible does three things in one, and does them very well. Ansible’s ‘batteries included’ approach means you have everything you need in one complete package.
- Efficient - No extra software on your servers means more resources for your applications. Also, since Ansible modules work via JSON, Ansible is extensible with modules written in a programming language you already know.
- Secure - Ansible uses SSH, and requires no extra open ports or potentially-vulnerable daemons on your servers.

Examples in the book are tested with the latest version of Ansible.
