### Features
|
||||
|
||||
Stuff that should probably be included in every configuration management,
|
||||
but is not. Or: Why I began to write cdist:
|
||||
|
||||
* Speed
|
||||
* Elegant code
|
||||
* Clean design
|
||||
* Elegant code and clean design
|
||||
* Type and core cleanly seperated
|
||||
* Small codebase in core
|
||||
* Good documentation (man pages)
|
||||
* Meaningful error messages
|
||||
* The no surprise factor
|
||||
* 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
|
||||
* Simple and well-known DSL: posix shell
|
||||
* It must be very easy to extend and debug cdist
|
||||
* Focus on reuse of existing functionality (like sh, ssh, find, rm, ...)
|
||||
* Easy upgrade: ***There is no need to update cdist on target hosts!***
|
||||
* cdist only needs to be update on the master server
|
||||
* 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

Cache:

Assume you want to configure stuff one host ("monitor node"),

|
||||
ask for all hosts, because cdist does not
|
||||
know which hosts are configured or may exist.
|
||||
|
||||
Example implementation
|
||||
|
||||
If cdist keeps ("caches") the configuration of every
|
||||
node it configures, each new node can query the
|
||||
cache for existing nodes that acquired the given
|
||||
configuration.
|
||||
remove --preseed from package_apt and add debconf_set_selection or similar
|
||||
-> much cleaner!
