filepath
        The absolute path to the validation file.

.. versionchanged:: 2019.2.0

Beginning with release codename ``2019.2.0``, this function has been
        enhanced, to be able to leverage the multi-engine template rendering
        of Salt, besides the possibility to retrieve the file source from
        remote systems, the URL schemes supported being:

- ``salt://``
        - ``http://`` and ``https://``
        - ``ftp://``
        - ``s3://``
        - ``swift:/``

Or on the local file system (on the Minion).

.. note::

The rendering result does not necessarily need to be YAML, instead
            it can be any format interpreted by Salt's rendering pipeline
            (including pure Python).

string
        .. versionadded:: 2019.2.0

The compliance report send as inline string, to be used as the file to
        send through the renderer system. Note, not all renderer modules can
        work with strings; the 'py' renderer requires a file, for example.

renderer: ``jinja|yaml``
        .. versionadded:: 2019.2.0

The renderer pipe to send the file through; this is overridden by a
        "she-bang" at the top of the file.

kwargs
        .. versionchanged:: 2019.2.0

Keyword args to pass to Salt's compile_template() function.

CLI Example:

.. code-block:: bash

salt '*' napalm.compliance_report ~/validate.yml
        salt '*' napalm.compliance_report salt://path/to/validator.sls

Validation File Example (pure YAML):

.. code-block:: yaml

- get_facts:
            os_version: 4.17

- get_interfaces_ip:
            Management1:
              ipv4:
                10.0.2.14:
                  prefix_length: 24
                _mode: strict

Validation File Example (as Jinja + YAML):

.. code-block:: yaml

- get_facts:
            os_version: {{ grains.version }}
        - get_interfaces_ip:
            Loopback0:
              ipv4:

    either from https://github.com/napalm-automation-community or defined in

        A list of configuration commands to be loaded on the remote device.

config_file
        Read the configuration commands from a file. The file can equally be a
        template that can be rendered using the engine of choice (see
        ``template_engine``).

This can be specified using the absolute path to the file, or using one
        of the following URL schemes:

- ``salt://``, to fetch the file from the Salt fileserver.
        - ``http://`` or ``https://``
        - ``ftp://``
        - ``s3://``
        - ``swift://``

exit_config_mode: ``True``
        Determines whether or not to exit config mode after complete.

delay_factor: ``1``
        Factor to adjust delays.

max_loops: ``150``
        Controls wait time in conjunction with delay_factor (default: ``150``).

strip_prompt: ``False``
        Determines whether or not to strip the prompt (default: ``False``).

strip_command: ``False``
        Determines whether or not to strip the command (default: ``False``).

config_mode_command
        The command to enter into config mode.

commit: ``False``
        Commit the configuration changes before exiting the config mode. This
        option is by default disabled, as many platforms don't have this
        capability natively.
