Hey hackers,
|
||||
|
||||
this README is for you, for those who want to dig into cdist, hack it or try
|
||||
to get a deeper understanding.
|
||||
|
||||
A lot of documentation is still missing, but running cdist-quickstart should
|
||||
give you an impression of how cdist works.
|
||||
to get a deeper understanding. Please read doc/man/cdist-hacker.text.
|
||||
|
||||
I hope you have a lot of fun with cdist, because it was also a lot of fun to
|
||||
develop it!
|
||||
|
||||
-- Nico, 20110304
|
||||
|
||||
|
||||
## Conventions
|
||||
|
||||
- All variables exported by cdist are prefixed with a double underscore (__)
|
||||
- All cdist-internal variables are prefixed with __cdist_ and are generally not exported.

cdist-type__apt_update_index - resynchronize the apt package index

|

|

DESCRIPTION
|
||||
-----------
|
||||
This cdist type allows you to resynchronize the package index files from their
|
||||
sources. In other words, it runs `apt-get update`.

||||

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

For instance, the monitor host would like to know,

which hosts are configured with the provider

"apache" and option --start true.
|

This requires the monitor node to be able to

query all other configured nodes. It can't

know which hosts are configured or may exist.

If cdist keeps ("caches") the configuration of every

cdist-hacker - How to get (stuff) into cdist

|

|

WELCOME
|

-------
|
||||
Welcome dear hacker! I invite you to a tour of pointers to
|
||||
get into the usable configuration mangament system, cdist.
|
||||
|
||||
The first thing to know is probably that cdist is brought to
|
||||
you by people who care about how code looks like and who think
|
||||
twice before merging or implementing a feature: Less features
|
||||

UNDERSTANDING CDIST INTERNALS
|
||||
-----------------------------
|
||||
IF you are interested in how cdist internally works, you can open
|
||||
bin/cdist-config and bin/cdist-deploy-to in your favorite editor and
|
||||
read the scripts bin/cdist-deploy-to calls. The magnificent HACKERS_README
|
||||
may be of great help as well.
|
||||
|
||||
|
||||
CODING CONVENTIONS (CORE)
|
||||
-------------------------
|
||||
- All variables exported by cdist are prefixed with a double underscore (__)
|
||||
- All cdist-internal variables are prefixed with __cdist_ and are generally not exported.
|
||||
|
||||
|
||||
HOW TO SUBMIT STUFF FOR INCLUSION INTO UPSTREAM CDIST
|
||||
-----------------------------------------------------
|
||||
If you did some cool changes to cdist, which you value as a benefit for
|
||||
everybody using cdist, you're welcome to propose inclusion into upstream.
|
||||
|
||||
There are though some requirements to ensure your changes don't break others
|
||||
work nor kill the authors brain:
|
||||
|
||||
- Code submission must be done via git
|
||||
- Code to be included should be branched of the upstream "master" branch
|
||||
- Exception: Bugfixes to a version branch
|
||||
- Code submissions must be in your master branch
|
||||
- Exception: If you only want a comment on your code, but not an inclusion.
|
||||
- Do not add conf/manifest/init - This file should only be touched in your
|
||||
private branch!
|
||||
|
||||
As soon as your work meets these requirements, you can contact me
|
||||
(IRC, Mailinglist, Phone, RFC 1149) and I'll check your code before
|
||||
including it.
|
||||
|
||||
|
||||
HOW TO SUBMIT A NEW TYPE
|
||||
------------------------
|
||||
Submitting a type works as described above, with the additional requirement
|
||||
that a corresponding manpage named man.text in asciidoc format with
|
||||
the manpage-name "cdist-type__NAME" is included in the type directory
|
||||
AND asciidoc is able to compile it.
