|

=============

Nico Schottelius <nico-cdist--@--schottelius.org>
|
||||
|
||||
|
||||
NAME
|
||||
----
|
||||
cdist-type - Functionality bundled
|
||||
|
||||
|
||||
SYNOPSIS
|
||||
--------
|
||||
__TYPE ID --parameter value [--parameter value ...]
|
||||
|
||||
__TYPE --parameter value [--parameter value ...] (for singletons)
|
||||
|
||||
|
||||
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
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
A list of supported types can be found in the cdist-reference(7) manpage.
|
||||
|
||||
|
||||
SINGLETON TYPES
|
||||
---------------
|
||||
If a type is flagged as a singleton, it may be used only
|
||||
once per host. This is useful for types which can be used only once on a
|
||||
system. Singleton types do not take an object name as argument.
|
||||
|
||||
Example:
|
||||
--------------------------------------------------------------------------------
|
||||
# __issue type manages /etc/issue
|
||||
__issue
|
||||
|
||||
# Probably your own type - singletons may use parameters
|
||||
__myfancysingleton --colour green
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
|
||||
HOW TO WRITE A NEW TYPE
|
||||
-----------------------
|
||||
A type consists of
|
||||
|
||||
- parameter (optional)
|
||||
- manifest (optional)
|
||||
- singleton (optional)
|
||||
- explorer (optional)
|
||||
- gencode (optional)
|
||||
|
||||
Types are stored below cdist/conf/type/. Their name should always be prefixed with
|
||||
two underscores (__) to prevent collisions with other executables in $PATH.
|
||||
|
||||
To implement a new type, create the directory **cdist/conf/type/__NAME**.
|
||||
|
||||
|
||||
DEFINING PARAMETERS
|
||||
-------------------
|
||||
Every type consists of required, optional and boolean parameters, which must
|
||||
each be declared in a newline separated file in ***parameter/required***,
|
||||
***parameter/required_multiple***, ***parameter/optional***,
|
||||
***parameter/optional_multiple*** and ***parameter/boolean***.
|
||||
Parameters which are allowed multiple times should be listed in
|
||||
required_multiple or optional_multiple respectively. All other parameters
|
||||
follow the standard unix behaviour "the last given wins".
|
||||
If either is missing, the type will have no required, no optional, no boolean
|
||||
or no parameters at all.
|
||||
|
||||
Example:
|
||||
--------------------------------------------------------------------------------
|
||||
echo servername >> cdist/conf/type/__nginx_vhost/parameter/required
|
||||
echo logdirectory >> cdist/conf/type/__nginx_vhost/parameter/optional
|
||||
echo server_alias >> cdist/conf/type/__nginx_vhost/parameter/optional_multiple
|
||||
echo use_ssl >> cdist/conf/type/__nginx_vhost/parameter/boolean
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
|
||||
USING PARAMETERS
|
||||
----------------
|
||||
The parameters given to a type can be accessed and used in all type scripts
|
||||
(e.g manifest, gencode-*, explorer/*). Note that boolean parameters are
|
||||
represented by file existence. File exists -> True,
|
||||
file does not exist -> False
|
||||
|
||||
Example: (e.g. in cdist/conf/type/__nginx_vhost/manifest)
|
||||
--------------------------------------------------------------------------------
|
||||
# required parameter
|
||||
servername="$(cat "$__object/parameter/servername")"
|
||||
|
||||
# optional parameter
|
||||
if [ -f "$__object/parameter/logdirectory" ]; then
|
||||
logdirectory="$(cat "$__object/parameter/logdirectory")"
|
||||
fi
|
||||
|
||||
# boolean parameter
|
||||
if [ -f "$__object/parameter/use_ssl" ]; then
|
||||
# file exists -> True
|
||||
# do some fancy ssl stuff
|
||||
fi
|
||||
|
||||
# parameter with multiple values
|
||||
if [ -f "$__object/parameter/server_alias" ]; then
|
||||
for alias in $(cat "$__object/parameter/server_alias"); do
|
||||
echo $alias > /some/where/usefull
|
||||
done
|
||||
fi
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
|
||||
INPUT FROM STDIN
|
||||
----------------
|
||||
Every type can access what has been written on stdin when it has been called.
|
||||
The result is saved into the ***stdin*** file in the object directory.
|
||||
|
||||
Example use of a type: (e.g. in cdist/conf/type/__archlinux_hostname)
|
||||
--------------------------------------------------------------------------------
|
||||
__file /etc/rc.conf --source - << eof
|
||||
...
|
||||
HOSTNAME="$__target_host"
|
||||
...
|
||||
eof
|
||||
--------------------------------------------------------------------------------
|
||||
If you have not seen this syntax (<< eof) before, it may help you to read
|
||||
about "here documents".
|
||||
|
||||
In the __file type, stdin is used as source for the file, if - is used for source:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
if [ -f "$__object/parameter/source" ]; then
|
||||
source="$(cat "$__object/parameter/source")"
|
||||
if [ "$source" = "-" ]; then
|
||||
source="$__object/stdin"
|
||||
fi
|
||||
....
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
|
||||
WRITING THE MANIFEST
|
||||
--------------------
|
||||
In the manifest of a type you can use other types, so your type extends
|
||||
their functionality. A good example is the __package type, which in
|
||||
a shortened version looks like this:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
os="$(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 "$@"
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
As you can see, the type can reference different environment variables,
|
||||
which are documented in cdist-reference(7).
|
||||
|
||||
Always ensure the manifest is executable, otherwise cdist will not be able
|
||||
to execute it. For more information about manifests see cdist-manifest(7).
|
||||
|
||||
|
||||
SINGLETON - ONE INSTANCE ONLY
|
||||
-----------------------------
|
||||
If you want to ensure that a type can only be used once per target, you can
|
||||
mark it as a singleton: Just create the (empty) file "singleton" in your type
|
||||
directory:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
touch cdist/conf/type/__NAME/singleton
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
This will also change the way your type must be called:
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
__YOURTYPE --parameter value
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
As you can see, the object ID is omitted, because it does not make any sense,
|
||||
if your type can be used only once.
|
||||
|
||||
|
||||
THE TYPE EXPLORERS
|
||||
------------------
|
||||
If a type needs to explore specific details, it can provide type specific
|
||||
explorers, which will be executed on the target for every created object.
|
||||
|
||||
The explorers are stored under the "explorer" directory below the type.
|
||||
It could for instance contain code to check the md5sum of a file on the
|
||||
client, like this (shortened version from the type __file):
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
if [ -f "$__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
|
||||
--------------------------
|
||||
There are two gencode scripts: ***gencode-local*** and ***gencode-remote***.
|
||||
The output of gencode-local is executed locally, whereas
|
||||
the output of gencode-remote is executed on the target.
|
||||
The gencode scripts can make use of the parameters, the global explorers
|
||||
and the type specific explorers.
|
||||
|
||||
If the gencode scripts 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.
|
||||
|
||||
If your type wants to save temporary data, that may be used by other types
|
||||
later on (for instance __file), you can save them in the subdirectory
|
||||
"files" below $__object (but you must create it yourself).
|
||||
cdist will not touch this directory.
|
||||
|
||||
If your type contains static files, it's also recommended to place them in
|
||||
a folder named "files" within the type (again, because cdist guarantees to
|
||||
never ever touch this folder).
|
||||
|
||||
|
||||
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 have a look at cdist-hacker(7) on
|
||||
how to submit it.
