Once we had the development environment taken care of, we looked at how to write modules using a Hello World example and how to extend Ansible with a new plugin that overrides functionality within the core Ansible plugin solution.
After that, we explored the plugin architecture and learned the various extension points that can be leveraged. This included action plugins, controller plugins, var plugins, and more.
