Hi *!
Here is a hack to emulate cfengines editfiles/Group behaviour.
{{{
$splice_dir = "/var/local/puppet/splice"
file { $splice_dir:
ensure => directory,
tag => "file_splice",
}
# Replace a section marked by
# comment_char {BEGIN,END} pattern
# with the given content
# if checksum is set to "none", no resource is defined for the edited
file
define file_splice ($file, $pattern = "PUPPET SECTION", $comment_char
= "#",
$content = "", $input_file = "", $checksum = md5)
{
case $checksum {
"none": {}
default: { file { $file: checksum => $checksum } }
}
# the splice command needs at least the BEGIN line in the file
append_if_no_such_line { "seed-$file-$pattern":
file => $file,
line => "$comment_char BEGIN $pattern",
require => File [ $file ],
}
case $content {
"": {
case $input_file {
"": {
fail ("either input_file or content have to be
supplied")
}
default: {
exec{ "/usr/local/bin/file_splice ''$input_file''
''$comment_char'' ''$pattern''
$file":
require => Append_if_no_such_line [
"seed-$file-$pattern" ],
subscribe => [ File[$input_file], File[$file] ],
}
}
}
}
default: {
$splice_file = "$splice_dir/$name"
file { $splice_file:
mode => 0600, owner => root, group => root,
content => $content,
require => File [ $splice_dir ],
}
exec{ "/usr/local/bin/file_splice ''$splice_file''
''$comment_char'' ''$pattern''
$file":
require => Append_if_no_such_line [
"seed-$file-$pattern" ],
subscribe => [ File [ $splice_file ], File[$file] ]
}
}
}
}
}}}
Usage example: manual conf.d style includes
{{{
# monitor this file for updates
$munin_includes = "$splice_dir/munin_conf_includes"
file { $munin_includes: checksum => md5, }
# this directory collects munin-node definitions from the munin-nodes
$NODESDIR = "/var/local/puppet/munin-nodes"
# concatenate all definitions into one file
exec { create_munin_includes:
command => "/bin/sh -c ''/bin/cat $NODESDIR/* >
$munin_includes''",
subscribe => File[$NODESDIR]
}
# include the file in the main config
file_splice { munin_conf_includes:
file => "/etc/munin/munin.conf",
input_file => "$splice_dir/munin_conf_includes",
require => Exec[create_munin_includes],
subscribe => File[$munin_includes],
}
}}}
Feedback, alternatives and improvements very welcome! Perhaps one day
I''ll
even make a better integrated version without a perl(!) script but a real
ruby type which recognizes when it should or should not run.
Regards, David
