[[!meta title="cdist - configuration management"]]

[[!toc levels=2]]

|
|
## Introduction
|
|
|
|
cdist configures your system and is similar to
|
|
other configuration management systems like
|
|
[cfengine](http://www.cfengine.org/),
|
|
[bcfg2](http://trac.mcs.anl.gov/projects/bcfg2),
|
|
[chef](http://wiki.opscode.com/display/chef/)
|
|
and [puppet](http://www.puppetlabs.com/), but
|
|
it ticks differently:
|
|
|
|
* cdist sticks completly to the KISS (keep it simple and stupid) paradigma
|
|
* cdist's core is very small (< 1k lines of code)
|
|
* There is only one type to extend cdist called ***type***.
|
|
* One main development target: ***It must be incredible easy to add new types.***
|
|
* cdist is UNIX
|
|
* It reuses existing tools like cat, find, mv, ...
|
|
* cdist's documentation is bundled as manpages
|
|
* cdist is written in POSIX shell
|
|
* No special requirements like high level interpreters needed on server or target
|
|
|
|
|
|
### Architecture
|
|
|
|
* Push mode (server pushes configuration)
|
|
* Pull mode planned (client triggers configuration)
|
|
* User defines configuration in shell scripts (called ***manifests***)
|
|
* Cdist generates internal configuration (cconfig style) and afterwards applies configuration
|
|
|
|
### Features
|
|
|
|
Stuff that should probably be included in every configuration management,
|
|
but is not. Or: The reason why I began to write cdist.
|
|
|
|
* Speed
|
|
* Elegant code
|
|
* Clean design
|
|
* Good documentation (man pages)
|
|
* Meaningful error messages
|
|
* No surprise factor
|
|
* Consistency in behaviour, naming and documentation
|
|
* Easy integration nacked installations
|
|
* Simple and well-known DSL: posix shell
|
|
* It is very easy to
|
|
* extend cdist
|
|
* debug cdist-core and cdist-types
|
|
* Focus on reuse of existing functionality
|
|
* ssh
|
|
* sh
|
|
* find, rm, ...
|
|
|
|
## Requirements
|
|
|
|
### Server
|
|
|
|
* A posix like shell
|
|
* SSH-Client
|
|
|
|
### Client ("target host")
|
|
|
|
* A posix like shell
|
|
* SSH-Server
|
|
|

|
## Getting cdist
|
|
|
|
You can clone cdist from git, which gives you the advantage of having
|
|
a version control in place for development of your own stuff as well.
|
|
|
|
There are at least two branches available:
|
|
|
|
* 1.0: stable branch of version 1.0
|
|
* next: preparing next cdist version
|
|
|
|
Other branches may be available as well for features or bugfixes, but they
|
|
may vanish at any point.
|
|
|
|
|
|
### Installation
|
|
|
|
To install cdist, execute the following commands:
|
|
|
|
git clone git://git.schottelius.org/cdist
|
|
cd cdist
|
|
export PATH=$PATH:$(pwd -P)/bin
|
|
|
|
|
|
### Update
|
|
|
|
As the stable branch always contains the stable code, you can upgrade
|
|
cdist using
|
|
|
|
git pull
|
|
|
|
If there are any incompatibilities, at least the minor version (1.0 -> 1.1)
|
|
will change and thus a git pull will never break your cdist installation
|
|
(in theory).
|
|
|
|
## Support
|
|
|
|
### IRC
|
|
|
|
You can join the development ***IRC channel***
|
|
[#cLinux on irc.freenode.org](irc://irc.freenode.org/#cLinux).
|
|
|
|
### Mailing list
|
|
|
|
Bug reports, questions, patches, etc. should be send to the
|
|
[cdist mailing list](http://l.schottelius.org/mailman/listinfo/cdist).
