and [puppet](http://www.puppetlabs.com/), but it ticks differently.
|

Here are some features that makes it unique:
|
||||
|
||||
* 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

Simplicity | There is only one type to extend cdist called ***type***
|
||||
Design | Type and core cleanly seperated
|
||||
Design | cdist sticks completly to the KISS (keep it simple and stupid) paradigma
|
||||
Design | Meaningful error messages - do not lose time debugging error messages
|
||||
Design | Consistency in behaviour, naming and documentation
|
||||
Design | No surprise factor: Only do what is obviously clear, no magic
|
||||
Design | Define target state, do not focus on methods or scripts
|
||||
Small core | cdist's core is very small - less code, less bugs
|
||||
Fast development | Focus on straightforwardness of type creation is a main development objective
|
||||
Requirements, Scalability | No central server needed, cdist operates in push mode and can be run from any computer
|
||||
Requirements, Scalability, Upgrade | cdist only needs to be updated on the master, not on the target hosts
|
||||
Requirements | cdist requires only SSH and a shell on the target

### Documentation
|
||||
|
||||
The cdist documentation is included as manpages in the distribution.
|
||||
You can [browse the documentation for the latest version online](man) as well.
|
||||
|
||||
### Architecture
|
||||
|
||||
* Push mode (server pushes configuration)
|
||||
* User defines configuration in shell scripts (called ***manifests***)
|
||||
* Generates internal configuration (cconfig style)
|
||||
* Uses ***types*** to generate code be executed on the target
|
||||
* And finally executes the code on the target / applies the configuration
|
||||
|
||||
### Features
|
||||
|
||||
* Elegant code and clean design
|
||||
* Type and core cleanly seperated
|
||||
* Small codebase in core
|
||||
* Good documentation (man pages)
|
||||
* Consistency in behaviour, naming and documentation
|
||||
* Meaningful error messages
|
||||
* Either standard error messages from tools or added description for clearification
|
||||
* The no surprise factor
|
||||
* No magic guessing of what the user wants
|
||||
* Simple and well-known DSL
|
||||
* Posix shell
|
||||
* Easy integration into bare metal installations
|
||||
* requires only ssh + sh
|
||||
* Easy upgrade
|
||||
* ***There is no need to update cdist on target hosts!***
|
||||
* cdist only needs to be updated on the master server(s)
|
||||
* Very easy to extend
|
||||
* Can be done via types, which can be stacked on top of others
|
||||
* Reuse of existing functionality
|
||||
* sh, ssh, find, rm, mv, ...
|
||||
* Very easy to debug
|
||||
* Just add set -x in the scripts
|
||||

||||
### OS support
