Nico Schottelius <nico-cdist--@--schottelius.org>
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
$__type_explorer/<explorer name> (type explorer).
In case of significant errors, the explorer may exit non-zero and return an
error message on stderr, which will cause the cdist run to abort.
You can also use stderr for debugging purposes while developing a new
explorer.
EXAMPLES
--------
A very simple explorer may look like this:
--------------------------------------------------------------------------------
hostname
--------------------------------------------------------------------------------
Which is in practise the "hostname" explorer.
A type explorer, which could check for the status of a package may look like this:
--------------------------------------------------------------------------------
if [ -f "$__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-reference - Variable, path and type reference for cdist $(git describe)
DESCRIPTION
-----------
Various scripts which are not in the core need information on how
to find information. This manpage summarises the available environment
variables, types and paths and clearifies with part may access which variables.
PATHS
-----
If not specified otherwise, all paths are relative to the checkout directory.
conf/::
Contains the (static) configuration like manifests, types and explorers.
conf/manifest/init::
This is the central entry point used by cdist-manifest-init(1).
It is an executable (+x bit set) shell script that can use
values from the explorers to decide which configuration to create
for the specified target host.
It should be primary used to define mapping from configurations to hosts.
conf/manifest/*::
All other files in this directory are not directly used by cdist, but you
can seperate configuration mappings, if you have a lot of code in the
manifest/init file. This may also be very helpful to have different admins
maintain different groups of hosts.
conf/explorer/<name>::
Contains explorers to be run on the target hosts, see cdist-explorer(7).
conf/type/::
Contains all available types, which are used to provide
some kind of functionality. See cdist-type(7).
conf/type/<name>/::
Home of the type <name>.
This directory is referenced by the variable __type (see below).
conf/type/<name>/man.text::
Manpage in Asciidoc format (nequired for inclusion into upstream)
conf/type/<name>/manifest::
Used to generate additional objects from a type.
conf/type/<name>/gencode::
Used to generate code to be executed on the client.
conf/type/<name>/parameters/required::
Parameters required by type, \n seperated list.
conf/type/<name>/parameters/optional::
Parameters optionally accepted by type, \n seperated list.
conf/type/<name>/explorer::
Location of the type specific explorers.
This directory is referenced by the variable __type_explorer (see below).
See cdist-explorer(7).
out/::
This directory contains output of cdist and is usually located
in a temporary directory and thus will be removed after the run.
This directory is referenced by the variable __global (see below).
out/explorer::
Output of general explorers.
out/object::
Objects created for the host.
out/object/<object>::
Contains all object specific information.
This directory is referenced by the variable __object (see below).
out/object/<object>/explorers::
Output of type specific explorers, per object.
tmp_dir::
A tempdir and a tempfile is used by cdist internally,
which will be removed when the scripts end automatically.
See cdist-config(1).
TYPES
-----
The following types are available:
eof
for type in man7/cdist-type__*; do
name_1="${type#man7/cdist-type}"
name_2="${name_1%.7}"
name="$name_2"
echo "- $name"
done
cat << eof

cdist-config-layout(7)
======================
Nico Schottelius <nico-cdist--@--schottelius.org>
NAME
----
cdist-config-layout - Usage of paths in cdist
DESCRIPTION
-----------
If not specified otherwise, all paths are relative to the configuration
directory, which is normally /etc/cdist (but can be changed using environment
variables, see cdist-environment(7)).
- conf_dir/:
Contains the (static) configuration like manifests, types and
explorers.
- conf_dir/manifest/init:
This is the central entry point used by cdist-manifest-init(1).
It is an executable (+x bit set) shell script that can use
values from the explorers to decide which configuration to create
for the specified target host.
It should be primary used to define mapping from configurations to hosts.
- conf_dir/manifest/*:
All other files in this directory are not directly used by Cdist, but you
can seperate configuration mappings, if you have a lot of code in the
manifest/init file. This may also be very helpful to have different admins
maintain different groups of hosts.
- conf_dir/explorer/<name>
Contains explorers to be run on the target hosts, see cdist-explorers(7).
- conf_dir/type/
Contains all available types, which are used to provide
some kind of functionality. See cdist-stages(7).
- conf_dir/type/<name>/manifest:
Used to generate additional objects from a type.
See cdist-stages(7), cdist-types(7).
- conf_dir/type/<name>/gencode:
Used to generate code to be executed on the client.
See cdist-types(7).
- conf_dir/type/<name>/parameters/required:
Parameters required by type, \n seperated list.
See cdist-types(7).
- conf_dir/type/<name>/parameters/optional:
Parameters optionally accepted by type, \n seperated list.
See cdist-types(7).
- conf_dir/type/<name>/explorer:
Location of the type specific explorers.
See cdist-explorers(7).
- out_dir/
This directory contains output of cdist and is mirrored into the
cache after a successful run. This directory may be placed below
the tmpdir or at any other location and is also available on the
target.
- out_dir/explorer:
Output of general explorers.
- out_dir/object:
Objects created for the host.
- out_dir/object/<object>/explorers:
Output of type specific explorers, per object.
- tmp_dir: Temporary storage
A tempdir and a tempfile is provided by cdist-config(1), which
will be removed when the scripts ends automatically.
FUTURE
------
The following functionality may be implemented in one of the next releases:
- cache_dir/
The cache contains the out_dir from previous runs, which
may also be used in types to gather information about other hosts
(like ssh-keys).
- cache_dir/host/<name>:
Contains the last out_dir of the specific host.

cdist-explorer(7)
=================
Nico Schottelius <nico-cdist--@--schottelius.org>
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.
