If a type is flagged as a singleton, it may be used only

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.
|
||||
Every type consists of required, optional and boolean parameters, which must
|
||||
be created in a newline seperated file in ***parameter/required***,
|
||||
***parameter/optional*** and ***parameter/boolean***. If either is missing,
|
||||
the type will have no required, no optional, no boolean or no parameters at
|
||||
all.
|
||||
|
||||
Example:
|
||||
--------------------------------------------------------------------------------
|
||||
echo servername >> conf/type/__nginx_vhost/parameter/required
|
||||
echo logdirectory >> conf/type/__nginx_vhost/parameter/optional
|
||||
echo use_ssl >> 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 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
