Practical Ansible - Second Edition

By: James Freeman, Fabio Alessandro Locati, Daniel Oh

Overview of this book

Ansible empowers you to automate a myriad of tasks, including software provisioning, configuration management, infrastructure deployment, and application rollouts. It can be used as a deployment tool as well as an orchestration tool. While Ansible provides simple yet powerful features to automate multi-layer environments using agentless communication, it can also solve other critical IT challenges, such as ensuring continuous integration and continuous deployment (CI/CD) with zero downtime. In this book, you'll work with the latest release of Ansible and learn how to solve complex issues quickly with the help of task-oriented scenarios. You'll start by installing and configuring Ansible on Linux and macOS to automate monotonous and repetitive IT tasks and learn concepts such as playbooks, inventories, and roles. As you progress, you'll gain insight into the YAML syntax and learn how to port between Ansible versions. Additionally, you'll understand how Ansible enables you to orchestrate multi-layer environments such as networks, containers, and the cloud. By the end of this Ansible book, you'll be well versed in writing playbooks and other related Ansible code to overcome all your IT challenges, from infrastructure-as-a-code provisioning to application deployments and handling mundane day-to-day maintenance tasks.

Summary

Ansible plugins are a core part of Ansible’s functionality and as we discovered in this chapter, we have been working with them throughout this book without even realizing it! Ansible’s modular design makes it easy to extend and add functionality, regardless of whether you are working with modules or the various types of plugins that are currently supported. Whether it’s to add a new filter for string processing or a new way of looking up data (or perhaps even a new connection mechanism to new technology), Ansible plugins provide a complete framework that can extend Ansible far beyond its already extensive capabilities.

In this chapter, we learned about the various types of plugins that are supported by Ansible, before exploring them in greater detail and looking at we you can obtain documentation and information on the existing ones. We then completed two practical examples to create two different types of plugins for Ansible while looking at the best...
