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.

In this section, we will therefore highlight a few of the more advanced facets to explore if you wish to learn more about AWX.

Role-based access control (RBAC)

So far, we have only looked at using AWX from the perspective of the built-in admin user. Of course, one of AWX's enterprise-level features is RBAC. This is achieved by the use of users and teams. A team is basically a group of users, and users can be a member of one or more teams.

Both users and teams can be created manually in the AWX user interface, or through integration with an external directory service, such as LDAP or Active Directory. In the case of directory...
