Description:

def compliance_report(filepath=None,
                      string=None,
                      renderer='jinja|yaml',
                      **kwargs):
    '''
    Return the compliance report.

    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:
                {{ grains.lo0.ipv4 }}:
                  prefix_length: 24
                _mode: strict
        - get_bgp_neighbors: {{ pillar.bgp.neighbors }}

    Output Example:

    .. code-block:: yaml
