Interface with Helm
:depends: pyhelm_ Python package

.. note::
This module use the helm-cli. The helm-cli binary have to be present in your Salt-Minion path.
Helm-CLI vs Salt-Modules
------------------------
This module is a wrapper of the helm binary.
All helm v3.0 command are implemented.
To install a chart with the helm-cli:
.. code-block:: bash
helm install grafana stable/grafana --wait --values /path/to/values.yaml
To install a chart with the Salt-Module:
.. code-block:: bash
salt '*' helm.install grafana stable/grafana values='/path/to/values.yaml' flags="['wait']"
