A module that adds data to the Pillar structure retrieved by an http request


Configuring the HTTP_YAML ext_pillar
====================================

Set the following Salt config to setup an http endpoint as the external pillar source:

.. code-block:: yaml

  ext_pillar:
    - http_yaml:
        url: http://example.com/api/minion_id
        username: username
        password: password
        header_dict: None
        auth: None

You can pass additional parameters, they will be added to the http.query call
:py:func:`utils.http.query function <salt.utils.http.query>`:

If the with_grains parameter is set, grain keys wrapped in can be provided (wrapped
in <> brackets) in the url in order to populate pillar data based on the grain value.

.. code-block:: yaml

  ext_pillar:
    - http_yaml:
        url: http://example.com/api/<nodename>
        with_grains: True

.. versionchanged:: 2018.3.0

    If %s is present in the url, it will be automatically replaced by the minion_id:

    .. code-block:: yaml

        ext_pillar:
          - http_json:
              url: http://example.com/api/%s
