cdist-config-layout - Usage of paths in cdist
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
-----------
|
|
|
|
|
If not otherwise specified, all paths are relative to the configuration
|
|
|
|
|
directory, which is normally /etc/cdist (but can be changed using environment
|
|
|
|
|
variables, see cdist-environment(7)).
|
|
|
|
|
|
|
|
|
|
- manifests/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 for 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.
|
|
|
|
|
|
|
|
|
|
- manifests/*: All other files in this directory
|
|
|
|
|
Cdist does not use them directly, 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.
|
|
|
|
|
|
|
|
|
|
- explorers/<name>
|
|
|
|
|
Contains explorers to be run on the target hosts, see cdist-explorers(7).
|
|
|
|
|
|
|
|
|
|
- types/
|
|
|
|
|
Contains all available types, which are used to provide
|
|
|
|
|
some kind of functionality. See cdist-stages(7).
|
|
|
|
|
|
|
|
|
|
- types/<name>/init:
|
|
|
|
|
Used to generate additional objects from a type.
|
|
|
|
|
See cdist-stages(7), cdist-types(7).
|
|
|
|
|
|
|
|
|
|
- types/<name>/gencode:
|
|
|
|
|
Used to generate code to be executed on the client.
|
|
|
|
|
See cdist-types(7).
|
|
|
|
|
|
|
|
|
|
- cache/
|
|
|
|
|
The cache contains results from previous runs, which may also
|
|
|
|
|
be used in types to gather information about other hosts
|
|
|
|
|
(like ssh-keys).
|
|
|
|
|
|
|
|
|
|
- cache/
|
|
|
|
|
|
|
|
|
|
- tmpdir: Temporary storage
|
|
|
|
|
A tempdir and a tempfile is provided by cdist-config(1), which
|
|
|
|
|
will be removed when the scripts ends automatically.
|
|
|
|
|
|
|
|
|
|
- tmpdir/cache/: New cache
|
|
|
|
|
This directory contains elements for the new cache of the host.
|
|
|
|
|
If all stages are completed successfully, the new cache is used
|
|
|
|
|
to replace the previous one.
|
|
|
|
|
|
|
|
|
|
- tmpdir/explorers/: Output of explorers
|
|
|
|
|
If the run was successful, the results are copied into the new cache.
|
|
|
|
|
|
|
|
|
|
- tmpdir/objects/: Objects created during run
|
|
|
|
|
If the run was successful, the results are copied into the new cache.

- If cdist encounters type in manifest,
|
|
|
|
|
a wrapper script is run, that creates a
|
|
|
|
|
new entry in the cconfig database and adds
|
|
|
|
|
attribute values. This defines a cconfig
|
|
|
|
|
tree, that may look as follows:
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
<hostname>/<type>/<id>/<parameters>:
|
|
|
|
|
|
|
|
|
|
myhost/__file/cdist_bin/source
|
|
|
|
|
myhost/__file/cdist_bin/destination
|
|
|
|
|
...
