cdist-manifest - Define types to be used
|
||||
|
||||
|
||||
DEFINE STATE IN THE INITIAL MANIFEST
|
||||
------------------------------------
|
||||
The **initial manifest** is the entry point for cdist to find out, which
|
||||
**objects** to configure on the selected host. Objects are instances of
|
||||
**types**, like in object orientated programming languages.
|
||||
An object is represented by the
|
||||
type + slash + object name: ***__file/etc/cdist-configured*** is an
|
||||
object of the type ***__file*** with the name ***etc/cdist-configured***.
|
||||
|
||||
Cdist searches for the initial manifest at **conf/manifest/init** and
|
||||
executes it as a shell script using **/bin/sh -e**.
|
||||
|
||||
Within this initial manifest, you define, which objects should be
|
||||
created on which host. To distinguish between hosts, you can use the
|
||||
environment variable **__target_host**. Let's have a look at a simple
|
||||
example:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
__cdistmarker
|
||||
|
||||
case "$__target_host" in
|
||||
localhost)
|
||||
__directory /home/services/kvm-vm --parents yes
|
||||
;;
|
||||
esac
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
This manifest says: Independent of the host, always use the type
|
||||
***__cdistmarker***, which creates the file **/etc/cdist-configured**,
|
||||
with the timestamp as content.
|
||||
The directory ***/home/services/kvm-vm***, including all parent directories,
|
||||
is only created on the host ***localhost***.
|
||||
|
||||
As you can see, there is no magic involved, the manifest is simple shell code that
|
||||
utilises cdist types. Every available type can be executed like a normal
|
||||
command. Use **ls conf/type** to get a list of available types. If you have
|
||||
setup the MANPATH correctly as, you can use **man cdist-reference** to access
|
||||
the reference with pointers to the manpages.
