[[!meta title="Why should I use cdist?"]]
|
||
|
|
|
||
|
|
There are several motivations to use cdist, these
|
||
|
|
are probably the most popular ones.
|
||
|
|
|
||
|
|
## Known language
|
||
|
|
|
||
|
|
Cdist is being configured in
|
||
|
|
[shell script](https://en.wikipedia.org/wiki/Shell_script).
|
||
|
|
Shell script is used by UNIX system engineers for decades.
|
||
|
|
So when cdist is introduced, your staff does not need to learn a new
|
||
|
|
[DSL](https://en.wikipedia.org/wiki/Domain-specific_language)
|
||
|
|
or programming language.
|
||
|
|
|
||
|
|
## Powerful language
|
||
|
|
|
||
|
|
Not only is shell scripting widely known by system engineers,
|
||
|
|
but it is also a very powerful language. Here are some features
|
||
|
|
which make daily work easy:
|
||
|
|
|
||
|
|
* Configuration can react dynamicly on explored values
|
||
|
|
* High level string manipulation (using sed, awk, grep)
|
||
|
|
* Conditional support (**if, case**)
|
||
|
|
* Loop support (**for, while**)
|
||
|
|
* Support for dependencies between cdist types
|
||
|
|
|
||
|
|
## More than shell scripting
|
||
|
|
|
||
|
|
If you compare regular shell scripting with cdist, there is one major
|
||
|
|
difference: When using cdist types,
|
||
|
|
the results are
|
||
|
|
[idempotent](https://en.wikipedia.org/wiki/Idempotence).
|
||
|
|
In practise, that means it does not matter in which order you
|
||
|
|
call cdist types, the result is always the same.
