|
||||
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
|
||||

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>/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).
|
||||

|

NAME
|
||||
----
|
||||
cdist-type-listing - Available types in cdist
|
||||
|
||||
|
||||
SYNOPSIS
|
||||
--------
|
||||
Types that are included in cdist $(git describe).
|
||||
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
Types are the main component of cdist and define functionality. If you
|
||||
use cdist, you'll write a type for every functionality you would like
|
||||
to use.
|
||||
|
||||
|
||||
HOW TO USE A TYPE
|
||||
-----------------
|
||||
You can use types from the initial manifest or the type manifest like a
|
||||
normal command:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
# Creates empty file /etc/cdist-configured
|
||||
__file /etc/cdist-configured --type file
|
||||
|
||||
# Ensure tree is installed
|
||||
__package tree --state installed
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
Internally cdist-type-emulator(1) will be called from cdist-manifest-run(1) to
|
||||
save the given parameters into a cconfig database, so they can be accessed by
|
||||
the manifest and gencode scripts of the type (see below).
|
||||
|
||||
|
||||
HOW TO WRITE A NEW TYPE
|
||||
-----------------------
|
||||
A type consists of
|
||||
|
||||
- parameter (optional)
|
||||
- manifest (optional)
|
||||
- explorer (optional)
|
||||
- gencode (optional)
|
||||
|
||||
Types are stored below conf/type/. Their name should always be prefixed with
|
||||
two underscores (__) to prevent collisions with other binaries in $PATH.
|
||||
|
||||
To begin a new type from a template, execute "cdist-type-template __NAME"
|
||||
and cd conf/type/__NAME.
|
||||
|
||||
|
||||
DEFINING PARAMETERS
|
||||
-------------------
|
||||
Every type consists of optional and required parameters, which must
|
||||
be created in a newline seperated file in parameters/required and
|
||||
parameters/optional. If either or both missing, the type will have
|
||||
no required, no optional or no parameters at all.
|
||||
|
||||
Example:
|
||||
--------------------------------------------------------------------------------
|
||||
echo servername >> conf/type/__nginx_vhost/parameter/required
|
||||
echo logdirectory >> conf/type/__nginx_vhost/parameter/optional
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
|
||||
WRITING THE MANIFEST
|
||||
--------------------
|
||||
In the manifest of a type you can use other types, so your type extends
|
||||
their functionality. A good example is the __package type, which in
|
||||
a shortened version looks like this:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
os="$(cat "$__global/explorer/os")"
|
||||
case "$os" in
|
||||
archlinux) type="pacman" ;;
|
||||
debian|ubuntu) type="apt" ;;
|
||||
gentoo) type="emerge" ;;
|
||||
*)
|
||||
echo "Don't know how to manage packages on: $os" >&2
|
||||
exit 1
|
||||
;;
|
||||
esac
|
||||
|
||||
__package_$type "$@"
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
As you can see, the type can reference different environment variables,
|
||||
which are documented in cdist-environment-variables(7).
|
||||
|
||||
Always ensure the manifest is executable, otherwise cdist will not be able
|
||||
to execute it.
|
||||
|
||||
|
||||
THE TYPE EXPLORERS
|
||||
------------------
|
||||
If a type needs to explore specific details, it can provide type specific
|
||||
explorers, which will be executed on the target for every created object.
|
||||
|
||||
The explorers are stored under the "explorer" directory below the type.
|
||||
It could for instance contain code to check the md5sum of a file on the
|
||||
client, like this (shortened version from real type __file):
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
if [ -f "$__object/parameter/destination" ]; then
|
||||
destination="$(cat "$__object/parameter/destination")"
|
||||
else
|
||||
destination="/$__object_id"
|
||||
fi
|
||||
|
||||
if [ -e "$destination" ]; then
|
||||
md5sum < "$destination"
|
||||
fi
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
|
||||
WRITING THE GENCODE SCRIPT
|
||||
--------------------------
|
||||
The gencode script can make use of the parameters, the global explorers
|
||||
and the type specific explorers. The output (stdout) of this script is
|
||||
saved by cdist and will be executed on the target.
|
||||
|
||||
If the gencode script encounters an error, it should print diagnostic
|
||||
messages to stderr and exit non-zero. If you need to debug the gencode
|
||||
script, you can write to stderr:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
# Debug output to stderr
|
||||
echo "My fancy debug line" >&2
|
||||
|
||||
# Output to be saved by cdist for execution on the target
|
||||
echo "touch /etc/cdist-configured"
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
|
||||
HINTS FOR TYPEWRITERS
|
||||
----------------------
|
||||
It must be assumed that the target is pretty dumb and thus does not have high
|
||||
level tools like ruby installed. If a type requires specific tools to be present
|
||||
on the target, there must be another type that provides this tool and the first
|
||||
type should create an object of the specific type.
|
||||
|
||||
|
||||
HOW TO INCLUDE A TYPE INTO UPSTREAM CDIST
|
||||
-----------------------------------------
|
||||
If you think your type may be useful for others, ensure it works with the
|
||||
current master branch of cdist and submit the git url containing the type for
|
||||
inclusion to the mailinglist **cdist at cdist -- at -- l.schottelius.org**.
|
||||
|
||||
Ensure a corresponding manpage named cdist-type__NAME is included.

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.

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.
