Fetch releases, create basejails, clone from the basejails, and start the jails. Create and display
the inventory. Use the `role vbotka.freebsd.iocage`_ instead of the :ref:`ug_plugins`.

Synopsis
^^^^^^^^

* At two managed nodes:
  In the playbook ``pb-iocage-fetch-base-clone.yml``, use the `role vbotka.freebsd.iocage`_ to:

  * fetch the release
  * create basejail
  * clone 3 jails from the basejail.

  In the playbook ``pb-iocage-list.yml``, use the `role vbotka.freebsd.iocage`_ to:

  * create the lists of bases and jails
  * optionally, display the lists.

  In the playbook ``pb-test-01.yml``:

  * create the inventory group ``test`` and compose variables
  * display the hosts and composed variables in the group ``test``
  * display all groups.

Requirements
^^^^^^^^^^^^

* `role vbotka.freebsd.iocage`_
* root privilege in the managed nodes
* activated ``iocage``

Notes
^^^^^

* This example demonstrates a functionality similar to :ref:`example_010`.

* The `role vbotka.freebsd.iocage`_ is preinstalled in this collection.
