## Testing cdist
|
||||
|
||||
cdist-build-explorer| ssh localhost
|
||||
|
||||
set -e
|
||||
git clone git://git.schottelius.org/cdist
|
||||
cd cdist
|
||||
export PATH=$PATH:$(pwd -P)/bin
|
||||
cdist-build-explorer | ssh localhost
|
||||
|
||||
|
||||
## Architecture
|
||||
|
||||
- User write shell scripts, which are run on the server
|
||||
- Shell scripts call cdist functions
|
||||
- cdist functions generate cconfig, which can be verified
|
||||
- if verified, generate "command file" to execute on the client
|
||||
- client only sees the commands
|
||||
- no special requirements on the client
|
||||
|
||||
## next: cdist-deploy-to
|
||||
|
||||
- sync conf/{lib/,modules,host/$name}

||||

||||
## Introduction
|
||||
|
||||
cdist configures your system. It is similar to
|
||||
[cfengine](http://www.cfengine.org/) and
|
||||
[puppet](http://www.puppetlabs.com/).
|
||||
[cfengine](http://www.cfengine.org/) and [puppet](http://www.puppetlabs.com/).
|
||||
It is inspired by both of those tools:
|
||||
|
||||
* Try to redo the great power you get
|
||||
* But leave out the bugs you also got
|
||||
|
||||
### Principles

||||
And cdist is UNIX:
|
||||
|
||||
cdist is unix: It's designed to reuse existing tools
|
||||
and does not need high level scripting language interpreters.
|
||||
It's designed to reuse existing tools,
|
||||
does not require high level scripting language interpreters
|
||||
and is equipped with manpages.
|
||||
|
||||
### Requirements
|
||||
### Architecture
|
||||
|
||||
* KISS (keep it simple and stupid)
|
||||
* Allow very easy extension of cdist (creating own types for instance)
|
||||
* Push (server pushes configuration) and Pull (client retrieves config) supported
|
||||
* User defines configuration in shell scripts using cdist functions
|
||||
* Cdist generates internal configuration (cconfig style) and afterwards applies configuration
|
||||
|
||||
## Requirements
|
||||
|
||||
### Server
|
||||
|
||||
* A posix like shell
|
||||
* SSH-Client (for push architecture)
|
||||
* SSH-Server (for pull architecture)
|
||||
|
||||
### Client
|
||||
|
||||
* A posix like shell
|
||||
* SSH-Client (for pull architecture)
|
||||
* SSH-Server (for push architecture)
