Modules are the very lifeblood of Ansible – without them, Ansible could not perform all of the complex and varied tasks it performs so well across a wide variety of systems. By virtue of being an open source project, it is incredibly easy to extend the functionality of Ansible by yourself, and in this chapter, we explored how you can, with a little Python knowledge, write your own custom module from scratch. Ansible is, at the time of writing, incredibly feature-rich, but this ease of customization and extension makes Ansible virtually limitless in terms of its potential, especially given the power and popularity of Python as a programming language.
In this chapter, we started with a recap of how to execute multiple modules using the command line. We then explored the process of interrogating the current module index, as well as how to obtain documentation about...
