cdist-explorer(7)

NAME
----
cdist-explorer - Explore the target systems
DESCRIPTION
-----------
Explorer are small shell scripts, which will be executed on the target
host. The aim of the explorer is to give hints to types on how to act on the
target system. An explorer outputs the result to stdout, which is usually
a one liner, but may be empty or multi line especially in the case of
type explorers.
There are general explorers, which are run in an early stage, and
type explorers. Both work almost exactly the same way, with the difference
that the values of the general explorers are stored in a general location and
the type specific below the object.
Explorers can reuse other explorers on the target system by calling
$__explorer/<explorer_name> (general and type explorer) or
$__type_explorer/<explorer name> (type explorer).
In case of significant errors, the explorer may exit non-zero and return an
error message on stderr, which will cause the cdist run to abort.
EXAMPLES
--------
A very simple explorer may look like this:
--------------------------------------------------------------------------------
hostname
--------------------------------------------------------------------------------
Which is in practise the "hostname" explorer.
A type explorer, which could check for the status of a package may look like this:
--------------------------------------------------------------------------------
if [ -f "$__object/parameter/name" ]; then
name="$(cat "$__object/parameter/name")"
else
name="$__object_id"
fi
# Except dpkg failing, if package is not known / installed
dpkg -s "$name" 2>/dev/null || exit 0
--------------------------------------------------------------------------------

NAME

cdist-explorer - Explore the target systems
DESCRIPTION
-----------
Cdist explorer are small shell scripts, which will be executed
on the target host. The aim of the explorer is to give hints
to types on how to act on the target system.
The explorer output the result of its investigation
to stdout and should be a one-liner. The output may be empty,
though.
Cdist knows about general explorers, which are run in an early
stage and type specific explorers. Both work exactly the same way,
with the difference that the values of the general explorers
are stored in a general location and the type specific below
the types.
Explorers can reuse other explorers on the target system
by calling ./<explorer_name> (i.e. explorers are run
from their location).
In case of significant errors, the shell script may exit
non-zero and return an error message on stderr, which
will cause the cdist run to abort.
