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

See the full `SaltStack Formulas installation and usage instructions
`_.

If you are interested in writing or contributing to formulas, please pay attention to the `Writing Formula Section
`_.

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 `_.

See `Formula Versioning Section `_ for more details.

If you need (non-default) configuration, please refer to:

- `how to configure the formula with map.jinja `_
- the ``pillar.example`` file
- the `Special notes`_ section

Contributing to this repo
-------------------------

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

**Commit message formatting is significant!!**

Please see `How to contribute `_ for more details.

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

`pre-commit `_ 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 `_, 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

Special notes
-------------

None.

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

.. contents::
:local:

``carbon-relay-ng``
^^^^^^^^^^^^^^^^^^^

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

Calls the install, config and service states below.

``carbon-relay-ng.install``
^^^^^^^^^^^^^^^^^^^^^^^^^^^

Installs the carbon-relay-ng package and manages some directories and files.

``carbon-relay-ng.config``
^^^^^^^^^^^^^^^^^^^^^^^^^^

Manages the configuration file using defined pillars.

``carbon-relay-ng.service``
^^^^^^^^^^^^^^^^^^^^^^^^^^^

Manages the carbon-relay-ng service.

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

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 ``carbon-relay-ng`` 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.
