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.

Was man mit cdist type machen kann.....
|
||||
|
||||
A cdist type describes some kind of functionality, starting from simple stuff
|
||||
like copying files until complex user auth/ldap/ kerberos infrastructure
|
||||
designs. The name of every type is prefixed with two underscores (__) by convention.
|
||||
|
||||
|
||||
, because
|
||||
types will be executed and the two underscores prevent collisions with real
|
||||
binaries (like "file").
|
||||
In general, types should be written independent of hosts (as in reusable
|
||||
code), but may be used implement functionality only needed on one host
|
||||
as well.
|
||||
It must be assumed that the clients are pretty dumb and thus do 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 must create an object of the specific type.
|
||||
If the generated code fails on the client, it must print diagnostistic messages on
|
||||
stderr and exit non-zero, so the configuration is aborted.
|
||||
Types may make use of other types to realise a new type or may implement some
|
||||
functionality on their own.
|
||||
|
||||
Types may consist of
|
||||
- a number of required and optional parameters they accept,
|
||||
- a manifest script that makes use of the parameters and may create other objects
|
||||
- explorers that explore type specific information on the target
|
||||
- a gencode script, that may generate code to be executed on the target
|
||||
|
||||
Every time a type is used, a new object is created of the specific type,
|
||||
with a type specific unique id that stores the parameters
