# == Define: concat
|
||||
#
|
||||
# Sets up so that you can use fragments to build a final config file,
|
||||
#
|
||||
# === Options:
|
||||
#
|
||||
# [*ensure*]
|
||||
# Present/Absent
|
||||
# [*path*]
|
||||
# The path to the final file. Use this in case you want to differentiate
|
||||
# between the name of a resource and the file path. Note: Use the name you
|
||||
# provided in the target of your fragments.
|
||||
# [*owner*]
|
||||
# Who will own the file
|
||||
# [*group*]
|
||||
# Who will own the file
|
||||
# [*mode*]
|
||||
# The mode of the final file
|
||||
# [*force*]
|
||||
# Enables creating empty files if no fragments are present
|
||||
# [*warn*]
|
||||
# Adds a normal shell style comment top of the file indicating that it is
|
||||
# built by puppet
|
||||
# [*force*]
|
||||
# [*backup*]
|
||||
# Controls the filebucketing behavior of the final file and see File type
|
||||
# reference for its use. Defaults to 'puppet'
|
||||
# [*replace*]
|
||||
# Whether to replace a file that already exists on the local system
|
||||
# [*order*]
|
||||
# [*ensure_newline*]
|
||||
# [*gnu*]
|
||||
# Deprecated
|
||||
#
|
||||
# === Actions:
|
||||
# * Creates fragment directories if it didn't exist already
|
||||
# * Executes the concatfragments.sh script to build the final file, this
|
||||
# script will create directory/fragments.concat. Execution happens only
|
||||
# when:
|
||||
# * The directory changes
|
||||
# * fragments.concat != final destination, this means rebuilds will happen
|
||||
# whenever someone changes or deletes the final file. Checking is done
|
||||
# using /usr/bin/cmp.
|
||||
# * The Exec gets notified by something else - like the concat::fragment
|
||||
# define
|
||||
# * Copies the file over to the final destination using a file resource
|
||||
#
|
||||
# === Aliases:
|
||||
#
|
||||
# * The exec can notified using Exec["concat_/path/to/file"] or
|
||||
# Exec["concat_/path/to/directory"]
|
||||
# * The final file can be referenced as File["/path/to/file"] or
|
||||
# File["concat_/path/to/file"]
