Cdist searches for the initial manifest at **conf/manifest/init** and Cdist searches for the initial manifest at **conf/manifest/init** and
executes it as a shell script using **/bin/sh -e**. 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:
--------------------------------------------------------------------------------
__file /etc/cdist-configured
case "$__target_host" in
localhost)
__directory /home/services/kvm-vm --parents yes
;;
esac
--------------------------------------------------------------------------------
This manifest says: Independent of the host, always create the (empty) file
***/etc/cdist-configured***, but create the directory ***/home/services/kvm-vm***,
including all parent directories, only on the host ***localhost***.
As you can see, there is no magic involved, the manifest is simple shell code that
utilises cdist types.
PARTS BELOW HERE ARE TO-BE-DONE
MORE ABOUT TYPES AND OBJECTS
----------------------------
All available types in cdist can be called like normal executables.
