PATHS

$HOME/.cdist
The standard cdist configuration directory relative to your home directory This is usually the place
you want to store your site specific configuration

cdist/conf/
The distribution configuration directory This contains types and explorers to be used

confdir
Cdist will use all available configuration directories and create a temporary confdir containing
links to the real configuration directories. This way it is possible to merge configuration
directories. By default it consists of everything in $HOME/.cdist and cdist/conf/. For more details
see cdist(1)

confdir/manifest/init
This is the central entry point. 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. Its intent
is to used to define mapping from configurations to hosts.

confdir/manifest/*
All other files in this directory are not directly used by cdist, but you can separate configuration
mappings, if you have a lot of code in the conf/manifest/init file. This may also be helpful to have
different admins maintain different groups of hosts.

confdir/explorer/<name>
Contains explorers to be run on the target hosts, see cdist-explorer(7).

confdir/type/
Contains all available types, which are used to provide some kind of functionality. See
cdist-type(7).

confdir/type/<name>/
Home of the type <name>. This directory is referenced by the variable __type (see below).

confdir/type/<name>/man.text
Manpage in Asciidoc format (required for inclusion into upstream)

confdir/type/<name>/manifest
Used to generate additional objects from a type.

confdir/type/<name>/gencode-local
Used to generate code to be executed on the source host

confdir/type/<name>/gencode-remote
Used to generate code to be executed on the target host

confdir/type/<name>/parameter/required
Parameters required by type, \n separated list.

confdir/type/<name>/parameter/optional
Parameters optionally accepted by type, \n separated list.

confdir/type/<name>/parameter/default/*
Default values for optional parameters. Assuming an optional parameter name of foo, it’s default
value would be read from the file confdir/type/<name>/parameter/default/foo.

confdir/type/<name>/parameter/boolean
Boolean parameters accepted by type, \n separated list.

confdir/type/<name>/explorer
Location of the type specific explorers. This directory is referenced by the variable __type_explorer
(see below). See cdist-explorer(7).

confdir/type/<name>/files
This directory is reserved for user data and will not be used by cdist at any time. It can be used
for storing supplementary files (like scripts to act as a template or configuration files).

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.

OBJECTS

       For object to object communication and tests, the following paths are usable within a object directory:

       files
           This directory is reserved for user data and will not be used by cdist at any time. It can be used
           freely by the type (for instance to store template results).

       changed
           This empty file exists in an object directory, if the object has code to be executed (either remote
           or local)

       stdin
           This file exists and contains data, if data was provided on stdin when the type was called.

ENVIRONMENT VARIABLES (FOR READING)

The following environment variables are exported by cdist:

__explorer
Directory that contains all global explorers. Available for: initial manifest, explorer, type
explorer, shell

__manifest
Directory that contains the initial manifest. Available for: initial manifest, type manifest, shell

__global
Directory that contains generic output like explorer. Available for: initial manifest, type manifest,
type gencode, shell

__messages_in

gencode

ENVIRONMENT VARIABLES (FOR WRITING)

       The following environment variables influence the behaviour of cdist:

       require
           Setup dependencies between objects (see cdist-manifest(7))

       CDIST_LOCAL_SHELL
           Use this shell locally instead of /bin/sh to execute scripts

       CDIST_REMOTE_SHELL

       CDIST_OVERRIDE
           Allow overwriting type parameters (see cdist-manifest(7))
