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.

Handling Windows authentication and encryption when using WinRM

Now that we have established the basic level of connectivity required for Ansible to perform tasks on a Windows host using WinRM, let's dig deeper into the authentication and encryption side of things. In the earlier part of the chapter, we used the basic authentication mechanism with a local account. While this is fine in a testing scenario, what happens in a domain environment? Basic authentication only supports local accounts, so clearly we need something else here. We also chose not to validate the SSL certificate (as it was self-signed), which again, is fine for testing purposes, but is not best practice in a production environment. In this section, we will explore options for improving the security of our Ansible communications with Windows.

Authentication mechanisms

Ansible, in fact, supports five different Windows authentication mechanisms when WinRM is used, as follows:

  • Basic: Supports...
