"""
A module to pull data from Foreman via its API into the Pillar dictionary


Configuring the Foreman ext_pillar
==================================

Set the following Salt config to setup Foreman as external pillar source:

.. code-block:: yaml

  ext_pillar:
    - foreman:
        key: foreman # Nest results within this key
        only: ['hostgroup_name', 'parameters'] # Add only these keys to pillar

  foreman.url: https://example.com/foreman_api
  foreman.user: username # default is admin
  foreman.password: password # default is changeme

The following options are optional:

.. code-block:: yaml

  foreman.api: apiversion # default is 2 (1 is not supported yet)
  foreman.verifyssl: False # default is True
  foreman.certfile: /etc/ssl/certs/mycert.pem # default is None
  foreman.keyfile: /etc/ssl/private/mykey.pem # default is None
  foreman.cafile: /etc/ssl/certs/mycert.ca.pem # default is None
  foreman.lookup_parameters: True # default is True

An alternative would be to use the Foreman modules integrating Salt features
in the Smart Proxy and the webinterface.

Further information can be found on `GitHub <https://github.com/theforeman/foreman_salt>`_.
