A SaltStack formula that is empty. It has dummy content to help with a quick
start on a new formula and it serves as a style guide.

General notes
-------------

See the full `SaltStack Formulas installation and usage instructions
<https://docs.saltstack.com/en/latest/topics/development/conventions/formulas.html>`_.

If you are interested in writing or contributing to formulas, please pay attention to the `Writing Formula Section
<https://docs.saltstack.com/en/latest/topics/development/conventions/formulas.html#writing-formulas>`_.

If you want to use this formula, please pay attention to the ``FORMULA`` file and/or ``git tag``,
which contains the currently released version. This formula is versioned according to `Semantic Versioning <http://semver.org/>`_.

See `Formula Versioning Section <https://docs.saltstack.com/en/latest/topics/development/conventions/formulas.html#versioning>`_ for more details.

-------------------------

Commit messages
^^^^^^^^^^^^^^^

**Commit message formatting is significant!!**

Please see `How to contribute <https://github.com/saltstack-formulas/.github/blob/master/CONTRIBUTING.rst>`_ for more details.

pre-commit
^^^^^^^^^^

`pre-commit <https://pre-commit.com/>`_ is configured for this formula, which you may optionally use to ease the steps involved in submitting your changes.
First install  the ``pre-commit`` package manager using the appropriate `method <https://pre-commit.com/#installation>`_, then run ``bin/install-hooks`` and
now ``pre-commit`` will run automatically on each ``git commit``. ::

  $ bin/install-hooks
  pre-commit installed at .git/hooks/pre-commit
  pre-commit installed at .git/hooks/commit-msg

None

Available states
----------------

.. contents::
   :local:

``unbound``
^^^^^^^^^^^^

*Meta-state (This is a state that includes other states)*.

This installs the unbound package,
manages the unbound configuration file and then
starts the associated unbound service.

``unbound.package``
^^^^^^^^^^^^^^^^^^^^

This state will install the unbound package only.

``unbound.config``
^^^^^^^^^^^^^^^^^^^

This state will configure the unbound service and has a dependency on ``unbound.install``
via include list.

``unbound.service``
^^^^^^^^^^^^^^^^^^^^

This state will start the unbound service and has a dependency on ``unbound.config``
via include list.

``unbound.clean``
^^^^^^^^^^^^^^^^^^

*Meta-state (This is a state that includes other states)*.

this state will undo everything performed in the ``unbound`` meta-state in reverse order, i.e.
stops the service,
removes the configuration file and
then uninstalls the package.

``unbound.service.clean``
^^^^^^^^^^^^^^^^^^^^^^^^^^

This state will stop the unbound service and disable it at boot time.

``unbound.config.clean``
^^^^^^^^^^^^^^^^^^^^^^^^^

This state will remove the configuration of the unbound service and has a
dependency on ``unbound.service.clean`` via include list.

``unbound.package.clean``
^^^^^^^^^^^^^^^^^^^^^^^^^^

This state will remove the unbound package and has a depency on
``unbound.config.clean`` via include list.

``unbound.subcomponent``
^^^^^^^^^^^^^^^^^^^^^^^^^

*Meta-state (This is a state that includes other states)*.

This state installs a subcomponent configuration file before
configuring and starting the unbound service.

``unbound.subcomponent.config``
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This state will configure the unbound subcomponent and has a
dependency on ``unbound.config`` via include list.

``unbound.subcomponent.config.clean``
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This state will remove the configuration of the unbound subcomponent
and reload the unbound service by a dependency on
``unbound.service.running`` via include list and ``watch_in``
requisite.

Testing
-------

Linux testing is done with ``kitchen-salt``.

Requirements
^^^^^^^^^^^^

* Ruby
* Docker

.. code-block:: bash

   $ gem install bundler
   $ bundle install
   $ bin/kitchen test [platform]

Where ``[platform]`` is the platform name defined in ``kitchen.yml``,
e.g. ``debian-9-2019-2-py3``.

``bin/kitchen converge``
^^^^^^^^^^^^^^^^^^^^^^^^

Creates the docker instance and runs the ``unbound`` main state, ready for testing.

``bin/kitchen verify``
^^^^^^^^^^^^^^^^^^^^^^

Runs the ``inspec`` tests on the actual instance.

``bin/kitchen destroy``
^^^^^^^^^^^^^^^^^^^^^^^

Removes the docker instance.

``bin/kitchen test``
^^^^^^^^^^^^^^^^^^^^

Runs all of the stages above in one go: i.e. ``destroy`` + ``converge`` + ``verify`` + ``destroy``.

``bin/kitchen login``
^^^^^^^^^^^^^^^^^^^^^

Gives you SSH access to the instance for manual testing.
