Module for working with Windows PowerShell DSC (Desired State Configuration)
This module is Alpha
This module applies DSC Configurations in the form of PowerShell scripts or
MOF (Managed Object Format) schema files.
Use the ``psget`` module to manage PowerShell resources.
The idea is to leverage Salt to push DSC configuration scripts or MOF files to
the Minion.
:depends:

Compile a DSC Configuration in the form of a PowerShell script (.ps1) and
apply it. The PowerShell script can be cached from the master using the
``source`` option. If there is more than one config within the PowerShell
script, the desired configuration can be applied by passing the name in the
``config`` option.
This command would be the equivalent of running ``dsc.compile_config``
followed by ``dsc.apply_config``.
Args:
path (str): The local path to the PowerShell script that contains the
DSC Configuration. Required.
source (str): The path to the script on ``file_roots`` to cache at the
location specified by ``path``. The source file will be cached
locally and then executed. If source is not passed, the config
script located at ``path`` will be compiled. Optional.
config_name (str): The name of the Configuration within the script to
apply. If the script contains multiple configurations within the
file a ``config_name`` must be specified. If the ``config_name`` is
not specified, the name of the file will be used as the
``config_name`` to run. Optional.
config_data (str): Configuration data in the form of a hash table that
will be passed to the ``ConfigurationData`` parameter when the
``config_name`` is compiled. This can be the path to a ``.psd1``
file containing the proper hash table or the PowerShell code to
create the hash table.
.. versionadded:: 2017.7.0
config_data_source (str): The path to the ``.psd1`` file on
``file_roots`` to cache at the location specified by
``config_data``. If this is specified, ``config_data`` must be a
local path instead of a hash table.
.. versionadded:: 2017.7.0
script_parameters (str): Any additional parameters expected by the
configuration script. These must be defined in the script itself.
.. versionadded:: 2017.7.0
salt_env (str): The salt environment to use when copying the source.
Default is 'base'
Returns:
bool: True if successfully compiled and applied, otherwise False
CLI Example:
To compile a config from a script that already exists on the system:
.. code-block:: bash
salt '*' dsc.run_config C:\\DSC\\WebsiteConfig.ps1
To cache a config script to the system from the master and compile it:
.. code-block:: bash
