cdist is an alternative to other configuration management systems like
But cdist ticks differently, here is the feature set that makes it unique:
Keywords | Description
Simplicity | There is only one type to extend cdist called ***type***
Design | Type and core cleanly seperated
Design | 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
Design | Push architecture: Instantly apply your changes
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, Security | Uses well-know [SSH](http://www.openssh.com/) as transport protocol
Requirements, Simplicity | Requires only shell and SSH server on the target
UNIX | Reuse of existing tools like cat, find, mv, ...
UNIX, familar environment, documentation | Is available as manpages and HTML
UNIX, simplicity, familar environment | cdist is written in POSIX shell
UNIX, simplicity, familar environment | cdist is configured in POSIX shell
The cdist documentation is included as manpages in the distribution.
* You can [browse the documentation of the latest version online](man) as well.
* Or you can watch the youtube **video**
[cdist installation and first usage in less than 60 seconds][http://www.youtube.com/watch?v=PRMjzy48eTI).
* Have a look at the [given speeches](speeches)
### OS support
cdist was tested or is know to run on at least
* [Mac OS X](http://www.apple.com/macosx/)
* A posix like shell
### Client ("target host")
* A posix like shell
## 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.
To install cdist, execute the following commands:
git clone git://git.schottelius.org/cdist
export PATH=$PATH:$(pwd -P)/bin
# If you want the manpages (requires gmake and asciidoc to be installed)
export MANPATH=$MANPATH:$(pwd -P)/doc/man
Afterwards you can run ***cdist-quickstart*** to get an impression on
how to use cdist.
### Available versions
There are at least the following branches available:
* Development: master
* Current Stable: 1.7 (Bugfixes, cleanups, new type and explorer rename)
* 1.6: New types, cleaned up \_\_package* types, internal cleanup
* 1.5: Focus on object orientation instead of global stage orientation
* 1.4: Support for redefiniton of objects (if equal)
* 1.3: Support for local and remote code execution (current stable)
* 1.2: Dependencies supported
* 1.1: \_\_file to \_\_file, \_\_directory, \_\_link migration
* 1.0: First official release
Other branches may be available for features or bugfixes, but they
may vanish at any point. To select a specific branch use
# Generic code
git checkout -b <name> origin/<name>
# Stay on a specific version
git checkout -b $version origin/$version
* git://github.com/telmich/cdist.git ([github](https://github.com/telmich/cdist))
* git://git.sans.ethz.ch/cdist ([sans](http://git.sans.ethz.ch/?p=cdist;a=summary))
To upgrade cdist in the current branch use
# Also update the manpages
export MANPATH=$MANPATH:$(pwd -P)/doc/man
If you stay on a version branche (i.e. 1.0, 1.1., ...), nothing should break.
The master branch on the other hand is the development branch and may not be
working, break your setup or eat the tree in your garden.
### Upgrading from 1.6 to 1.7
* If you used the global explorer **hardware_type**, you need to change
your code to use **machine** instead.
### Upgrading from 1.5 to 1.6
* If you used **\_\_package_apt --preseed**, you need to use the new
type **\_\_debconf_set_selections** instead.
* The **\_\_package** types accepted either --state deinstalled or
--state uninstaaled. Starting with 1.6, it was made consistently
to --state removed.
### Upgrading from 1.3 to 1.5
### Upgrading from 1.2 to 1.3
Rename **gencode** of every type to **gencode-remote**.
### Upgrading from 1.1 to 1.2
### Upgrading from 1.0 to 1.1
In 1.1 the type **\_\_file** was split into **\_\_directory**, **\_\_file** and
**\_\_link**. The parameter **--type** was removed from **\_\_file**. Thus you
need to replace **\_\_file** calls in your manifests:
* Remove --type from all \_\_file calls
* If type was symlink, use \_\_link and --type symbolic
* If type was directory, use \_\_directory
You can join the development ***IRC channel***
[#cstar on irc.freenode.org](irc://irc.freenode.org/#cstar).
### Mailing list
Bug reports, questions, patches, etc. should be send to the
[cdist mailing list](http://l.schottelius.org/mailman/listinfo/cdist).

You can request commercial support for cdist from
