Special notes
-------------
What this formula can do
^^^^^^^^^^^^^^^^^^^^^^^^
Many times, in the process of setting up a host/vm, you need to install/remove
packages with no extra configuration or setup. This formula tries to help with
that. It can get a list of packages from a pillar, and it will try to install
them.
It provides a few states to install/remove system packages (currently
Debian/Redhat families), Python packages (using pip states) and Ruby gems
(using gem states).
It can also provide basic dependency management on certain other states/packages.
What this formula can't do
^^^^^^^^^^^^^^^^^^^^^^^^^^
This formula is not intended to configure packages, nor setup services or daemons.
When you need to do that for a package, you should probably be using another
formula.
Available states
----------------
.. contents::
:local:
``packages``
^^^^^^^^^^^^
*Meta-state (This is a state that includes other states)*.
Runs all the other states in the formula.
``packages.pkgs``
^^^^^^^^^^^^^^^^^
Allows you to manage system's packages. You can specify:
* ``held``: either a list of packages or a dict of `package: version`,
which will be installed and pinned to the installed version using
SaltStack's `hold/unhold` capability.
When upgrading a version, the package will be temporarily unheld,
upgraded and then held again.
In the RedHat family, helding packages depend on a yum plugin that you
need to install. In order to do this, you can add it using this formula, adding
to your ``pkgs.required.pkgs`` one of the following packages:
+ CentOS
.. code-block:: yaml
packages:
pkgs:
required:
pkgs:
- yum-plugin-versionlock
+ Fedora > 26 with Python3:
.. code-block:: yaml
packages:
pkgs:
required:
pkgs:
- python3-dnf-plugin-versionlock
+ Fedora > 26 with Python2:
.. code-block:: yaml
packages:
pkgs:
required:
pkgs:
- python2-dnf-plugin-versionlock
* ``wanted``: a list of packages which will be installed. Packages in this
list will be automatically unheld so, if you want to permanently unheld a
package you were previously helding to a version, just move it from the
``held`` dict to this list.
* ``unwanted`` system packages, which will be uninstalled.
* ``required system packages`` on which any of the ``wanted`` packages depend
for their correct installation.
* ``required states`` on which any of the ``wanted`` packages depend for their
correct installation.
``packages.pips``
^^^^^^^^^^^^^^^^^
You can specify:
* ``wanted`` python packages, which will be installed using pip. Requires you
specify the correct ``python-pip`` package for your distro, as a dependency
(see the pillar.example)
* ``unwanted`` python packages, which will be uninstalled using pip.
* ``required system packages`` on which any of the ``wanted`` python packages
depend for their correct installation. Usually, a ``python-pip`` package and/or
some other compiler packages are required.
* ``required states`` on which any of the ``wanted`` packages depend for their
correct installation (ie, ``epel`` for RedHat families).
``packages.gems``
^^^^^^^^^^^^^^^^^
You can specify:
* ``wanted`` ruby packages, which will be installed using gem. Requires you
specify the correct ``ruby`` package for your distro, as a dependency
(see the pillar.example)
* ``unwanted`` ruby packages, which will be uninstalled using gem.
* ``required system packages`` on which any of the ``wanted`` ruby packages
depend for their correct installation. Usually, a ``ruby`` package and/or
some other compiler packages are required.
* ``required states`` on which any of the ``wanted`` packages depend for their
correct installation (ie, ``epel`` for RedHat families).
``packages.npms``
^^^^^^^^^^^^^^^^^
This formula **DOES NOT** install ``nodejs/npm``, as it's outside of its scope:
nodejs/npm that comes with the distros is usually outdated, so it's required to add
a repo, run scripts, etc, and this formula manages packages :)
You can use the `nodejs-formula <https://github.com/saltstack-formulas/node-formula>`_
and add a dependency for it in the pillar `npms:required:sls` (see the pillar.example)
You can specify:
* ``wanted`` npm packages, which will be installed using npm. Requires you
specify the correct ``npm`` package for your distro, as a dependency
(see the pillar.example)
* ``unwanted`` npm packages, which will be uninstalled using npm.
* ``required system packages`` on which any of the ``wanted`` npm packages
depend for their correct installation. Usually, a ``npm`` package and/or
some other compiler packages are required.
* ``required states`` on which any of the ``wanted`` packages depend for their
correct installation (ie, ``epel`` for RedHat families).
``packages.archives``
^^^^^^^^^^^^^^^^^^^^^
'Archive file` handler for common 'download' and 'checksum' states. All formats recognized by `salt.states.archive.extracted` (tar, rar, zip, etc) will be extracted. Alternatively `raw` formats are supported (`raw`, `bin`,) for standard and binary executable files.
* ``wanted`` archive package software, which will be installed by extraction.
* ``unwanted`` archive package software, which are uninstalled by directory removal.
* ``required archive packages`` on which any of the ``wanted`` items depend on. Optional.
``packages.snaps``
^^^^^^^^^^^^^^^^^^
You can specify:
* ``wanted`` snapd packages, which will be installed using snap.
* ``classic`` snapd packages, chich will be installed using snap with classic confinement.
* ``unwanted`` snapd packages, which will be uninstalled using snap.
* ``required system packages`` on which any of the ``wanted`` snapd packages
depend for their correct installation.
* ``required states`` on which any of the ``wanted`` packages depend for their
correct installation (ie, ``epel`` for RedHat families).
.. note::
Centos has no native ``snapd`` package at this time.
``packages.golang``
^^^^^^^^^^^^^^^^^^^
You can specify:
* ``clean`` golang packages, removed using ``go clean -i <item>...``.
* ``goget`` golang packages, installed using ``go get``.
``packages.remote_pkgs``
^^^^^^^^^^^^^^^^^^^^^^^^
You can specify a dictionary of remote system packages (deb/rpm) that you want
to install, in the format:
``name: url``
``packages.chocolatey``
^^^^^^^^^^^^^^^^^^^^^^^
You can specify:
* ``wanted`` chocolatey packages, which will be installed using chocolatey. Requires you
specify the correct ``chocolatey`` package (see the pillar.example)
* ``unwanted`` chocolatey packages, which will be uninstalled using chocolatey.
* ``required system packages`` on which any of the ``wanted`` system packages
depend for their correct installation.
* ``required states`` on which any of the ``wanted`` packages depend for their
correct installation (ie, ``regedit`` for configurations).
.. note::
You must configure `winrepo-ng <https://github.com/saltstack/salt-winrepo-ng>`_ in order to install chocolatey required 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 ``packages`` main states, 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.
Testing with Vagrant
--------------------
Windows/FreeBSD/OpenBSD testing is done with ``kitchen-salt``.
Requirements
^^^^^^^^^^^^
* Ruby
* Virtualbox
* Vagrant
Setup
^^^^^
.. code-block:: bash
$ gem install bundler
$ bundle install --with=vagrant
$ bin/kitchen test [platform]
Where ``[platform]`` is the platform name defined in ``kitchen.vagrant.yml``,
e.g. ``windows-81-latest-py3``.
Note
^^^^
When testing using Vagrant you must set the environment variable ``KITCHEN_LOCAL_YAML`` to ``kitchen.vagrant.yml``. For example:
.. code-block:: bash
$ KITCHEN_LOCAL_YAML=kitchen.vagrant.yml bin/kitchen test # Alternatively,
$ export KITCHEN_LOCAL_YAML=kitchen.vagrant.yml
$ bin/kitchen test
Then run the following commands as needed.
``bin/kitchen converge``
^^^^^^^^^^^^^^^^^^^^^^^^
Creates the Vagrant instance and runs the ``packages`` main states, ready for testing.
``bin/kitchen verify``
^^^^^^^^^^^^^^^^^^^^^^
Runs the ``inspec`` tests on the actual instance.
``bin/kitchen destroy``
^^^^^^^^^^^^^^^^^^^^^^^
Removes the Vagrant instance.
``bin/kitchen test``
^^^^^^^^^^^^^^^^^^^^
Runs all of the stages above in one go: i.e. ``destroy`` + ``converge`` + ``verify`` + ``destroy``.
``bin/kitchen login``
^^^^^^^^^^^^^^^^^^^^^
Gives you RDP/SSH access to the instance for manual testing.
