Did you know a large portion of Ansible’s functionality comes from the Ansible plugin system? These important pieces of code augment Ansible’s core functionality such as parsing and loading inventory and Playbooks, running Playbooks and reading the results. Essentially, Ansible uses plugins to extend what the system is doing under the hood.
In this blog, I’ll review each of these plugins and offer a high-level overview on how to write your own plugin to extend Ansible functionality.
Action Plugins
One of the core critical plugins used by Ansible are action plugins. Anytime you run a module, Ansible first runs an action plugin.
Action plugins are a layer between the executor engine and the module and allow for controller-side actions to be taken before the module is executed. A good example of this is the template module. If you look at template.py in the modules directory, it’s basically a Python stub with documentation strings, everything is done by the action plugin.

I’ve even gone so far as to see an article of top 7 somethings broken down into 33(!) pages, each with 19 ads and about 14 words.
Writers competing for eyeballs are always going to lose in the end. Because the attention span of the average human doesn’t dally long enough to make a difference. Think of yourself in a crowded room. Your eyes dart back and forth and all around trying to find something Continue reading
