Marathon
========

Proxy minion for managing a Marathon cluster.

Dependencies
------------

- :mod:`marathon execution module (salt.modules.marathon) <salt.modules.marathon>`

Pillar
------

The marathon proxy configuration requires a 'base_url' property that points to
the marathon endpoint:

.. code-block:: yaml

    proxy:
      proxytype: marathon
      base_url: http://my-marathon-master.mydomain.com:8080

.. versionadded:: 2015.8.2
