Mastering Ansible, 4th Edition - Fourth Edition

By: James Freeman, Jesse Keating

Overview of this book

Ansible is a modern, YAML-based automation tool (built on top of Python, one of the world’s most popular programming languages) with a massive and ever-growing user base. Its popularity and Python underpinnings make it essential learning for all in the DevOps space. This fourth edition of Mastering Ansible provides complete coverage of Ansible automation, from the design and architecture of the tool and basic automation with playbooks to writing and debugging your own Python-based extensions. You'll learn how to build automation workflows with Ansible’s extensive built-in library of collections, modules, and plugins. You'll then look at extending the modules and plugins with Python-based code and even build your own collections — ultimately learning how to give back to the Ansible community. By the end of this Ansible book, you'll be confident in all aspects of Ansible automation, from the fundamentals of playbook design to getting under the hood and extending and adapting Ansible to solve new automation challenges.

Contributing to the Ansible project

Not all modifications need to be for local site requirements. Ansible users will often identify an enhancement that could be made to the project that others would benefit from. These enhancements can be contributed via a collection, and in the new structure of Ansible that proceeds from version 3.0, this is likely to be the most suitable route for most people. In this case, you will be able to follow the guidance given in Chapter 2, Migrating from Earlier Ansible Versions, to build and release a collection. However, what if you develop the next killer plugin or filter that should be added to the ansible-core project itself? In this section, we'll look at how you can do this. Contributions could be in the form of updates to an existing built-in module or core Ansible code, updates to documentation, new filters or plugins, or simply testing proposed contributions from other community members.
