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.

Summary

Ansible handles Windows hosts as effectively as Linux (and other Unix) ones. In this chapter, we covered both how to run Ansible from a Windows host, and how to integrate Windows hosts with Ansible for automation, including the authentication mechanisms, encryption, and even the basics of Windows-specific playbooks.

You have learned that Ansible can run from a recent build of Windows that supports WSL, and how to achieve this. You have also learned how to set up Windows hosts for Ansible control and how to secure this with Kerberos authentication and encryption. You also learned how to set up and use the new and experimental support for SSH communication by Ansible with Windows hosts. Finally, you learned the basics of authoring Windows playbooks, including finding the correct modules for use with Windows hosts, escaping special characters, creating directories and copy files for the host, installing packages, and even running raw shell commands on the Windows host with...
