NAME
|
|
----
|
|
cdist-types - Functionality bundled
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
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 (__),
|
|
because types will be executed and the two underscores prevent
|
|
collisions with real binaries (like "file").
|
|
|
|
It must be assumed that the clients are pretty dumb
|
|
and thus do not have high level tools like python
|
|
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 call
|
|
"exit 1", so the configuration is aborted.
|
|
|
|
- are independent of hosts in general
|
|
- may make use of other types to realise a new type
|
|
- can overwrite stuff (HOW?)
|
|
- overwrite in own tree?
|
|
- needs knowledge of inherited provider
|
|
- similar to current situation in puppet,
|
|
but more like reusable defines
|
|
- or may implement some functionality on their own
|
|
|
|
|
|
HOW TO WRITE A NEW TYPE (TODO)
|
|
-----------------------
|
|
Assume you want to create the new type named "coffee":
|
|
|
|
Create the directory /etc/cdist/types/coffee/
|
|
Create the file /etc/cdist/types/coffee/README containing a description of the
|
|
type.
|
|
If your type supports attributes, create the directory /etc/cdist/types/coffee/
|
|
attributes.
|
|
For each attribute, create the file
|
|
/etc/cdist/types/coffee/attributes/$attribute_name which contains
|
|
|
|
a short description on the first line
|
|
then a blank line
|
|
then a long description (probably over several lines)
|
|
|
|
If you think your type may be useful for others, submit it for inclusion
|
|
into cdist at cdist -- at -- l.schottelius.org.
|
|
|
|
Create /etc/cdist/types/coffee/init which reads $configinput
|
|
(either via cconfig or via environment) and outputs a block of
|
|
shell code suitable for running on the client.
