Discover how to extend and embed Ansible with Python in this informative conference talk from EuroPython 2015. Begin with a rapid introduction to Ansible for newcomers, then delve into advanced techniques for Pythonistas. Learn to leverage Ansible's Python API for embedding, and explore methods to extend its functionality through custom modules, dynamic inventory scripts, and plugins. Gain insights into creating Ansible modules, understanding their structure, and implementing best practices. Explore practical examples, including a Flask Facter and a Taiga issue module. Dive into dynamic inventory scripts, callback plugins, lookup plugins, filter plugins, action plugins, vars plugins, and cache plugins. While prior Ansible experience is beneficial, beginners will also gain valuable insights into the tool's integration capabilities.
