Clone selected `Salt formulas

<http://docs.saltstack.com/en/latest/topics/development/conventions/formulas.html>`_
|
|
Git repositories under ``/srv/formulas`` and makes them available in the
|
|
relevant ``file_roots`` settings. Pillar data can be used to customize all
|
|
paths, URLs, etc.
|
|
|
|
Here's a minimal pillar sample installing two formulas in the base
|
|
environment.
|
|
|
|
::
|
|
|
|
salt_formulas:
|
|
list:
|
|
base:
|
|
- salt-formula
|
|
- openssh-formula
|
|
|
|
See pillar.example for an exhaustive list of settings available via pillar. Note
|
|
that by default this state:
|
|
|
|
- downloads the latest formulas from the `saltstack-formulas project
|
|
<https://github.com/saltstack-formulas>`_ on GitHub.
|
|
- does not update the local repositories after the initial clone.
|
|
This is a safety measure since you do not control how the official
|
|
repositories evolve.
|
|
|
|
If you configure the state to download the formulas from repositories that
|
|
you control, then you can safely enable the
|
|
``salt_formulas:git_opts:default:update`` pillar setting to ``True``.
|
|
|
|
``Configuration``
|
|
=================
|
|
Every option available in the templates can be set in pillar. Settings under 'salt' will be overridden by more specific settings under ``salt['master']``, ``salt['minion']`` or ``salt['cloud']``
|
|
|
|
::
|
|
|
|
salt:
|
|
ret_port: 4506
|
|
master:
|
|
user: saltuser
|
|
...
|
|
minion:
|
|
user: saltuser
|
|
...
|
|
cloud:
|
|
providers: ec2
|
|
...
|
|
|
|
``Extending``
|
|
=============
|
|
Additional templates can be added by the user under salt/files/minion.d and master.d. This might be useful if, for example, a recently-added configuration option is not yet provided by the default template.
|
|
|
|
``Vagrant``
|
|
===========
|
|
|
|
Executing the provided `Vagrantfile <http://www.vagrantup.com/>`_ will create a Ubuntu 14.04 VM, add the default Saltstack Repository and install the current stable version.
|
|
|
|
The folders inside the VM will be set up in a way that enables you to simply execute 'sudo salt "*" state.highstate' to apply the salt formula to the VM, using the pillar.example config. You can check /etc/salt/ for results.
|
|
|
|
Remember, you will have to run ``state.highstate`` or ``state.sls salt.(master|minion|cloud)`` manually.
