Vars Plugins
------------
They inject additional variable data into ansible runs that did not come from an inventory source, playbook, or command line.
The :doc:`host_group_vars <vars/host_group_vars>` plugin shipped with Ansible provides reading variables from :ref:`host_vars` and :ref:`group_vars`.
Enabling Vars Plugins
+++++++++++++++++++++
You can activate a custom vars plugins by either dropping it into a ``vars_plugins`` directory adjacent to your play or inside a role
or by putting it in one of the directory sources configured in :doc:`ansible.cfg <../config>`.
Plugin Lists
++++++++++++
You can use ``ansible-doc -t vars -l`` to see the list of available plugins,
use ``ansible-doc -t vars <plugin name>`` to see specific documents and examples.
