Use case
^^^^^^^^

Use the `iocage`_ template ``ansible_init`` created in :ref:`example_524`. Configure the repo
`ansible-conf-init`_ to pull the jails' configuration from the repo `ansible-conf-test`_. Create
jails from the template. Use ``class=test`` to select the configuration. Run `ansible-pull`_
asynchronously.

Synopsis
^^^^^^^^

* At a managed node:

  * In the playbook `vbotka.freebsd.pb_iocage_project_create_from_templates.yml`_ create jails from
    the template ``ansible_init``.

  * Wait for ``ansible-pull`` to configure the jails and display the test files.

.. note::

   The only difference compared to :ref:`example_524` is the dictionary used for the jails'
   configuration. In this example, the jails (baz and qux) are not included in the ``ai_db_host``
   dictionary; instead, they are configured from the ``ai_db_class`` dictionary. See the repository
   `ansible-conf-init`_.
