Plugins
=======
Plugins are the source of all logic used in building a config. They can perform one of several tasks:
#. Generating configuration inventory lists for clients
#. Generating configuration entry contents for clients
#. Probing client-side state (like hardware inventory, etc) -- the generic client probing mechanism is described at :doc:`probes`.
#. Automating administrative tasks (e.g. :doc:`sshbase` which automates ssh key management)
#. Generating client per-entry installation decision-lists
Enabling Plugins
================
In order for the bcfg2 server to use a plugin, it needs to be listed on the *plugins* line in bcfg2.conf.
Default Plugins
===============
The `Bcfg2 repository`_ has the default plugin list currently distributed with Bcfg2: http://trac.mcs.anl.gov/projects/bcfg2/browser/trunk/bcfg2/src/lib/Server/Plugins.
.. _Bcfg2 repository: http://trac.mcs.anl.gov/projects/bcfg2/browser/trunk/bcfg2/src/lib/Server/Plugins.
Metadata (Grouping)
-------------------
* :doc:`bb`
* :doc:`metadata`
Each of these plugins has a corresponding subdirectory with the same name in the Bcfg2 repository.
Abstract Configuration (Structures)
-----------------------------------
* :doc:`base`
* :doc:`bundler`
Each of these plugins has a corresponding subdirectory with the same name in the Bcfg2 repository.
Literal Configuration (Generators)
----------------------------------
* :doc:`account`
* :doc:`actions`
* :doc:`cfg`
* :doc:`decisions`
* :doc:`deps`
* :doc:`hostbase`
* :doc:`nagiosgen`
* :doc:`packages`
* :doc:`pkgmgr`
* :doc:`rules`
* :doc:`sshbase`
* :doc:`tcheetah`
* :doc:`tgenshi`
Each of these plugins has a corresponding subdirectory with the same name in the Bcfg2 repository.
Statistics Plugins
------------------
* :doc:`dbstats`
* :doc:`statistics`
DBStats can be enabled by adding it to the plugins line in /etc/bcfg2.conf.
Version Plugins
---------------
* :doc:`bzr`
* :doc:`fossil`
* :doc:`git`
* :doc:`svn`
Plugin Roles (in 1.0)
=====================
In version 1.0, plugins have been refactored into a series of roles. This are fine-grained plugin capabilities that govern how the server core interacts with plugins.
More details can be found in :doc:`plugin-roles`
