Should the following approach to optionally including site-specific
information in modules work? It's the third pattern documented at
http://serialized.net/2009/07/puppet-module-patterns/
In my case, I have
modules/manifests/ntp/init.pp
import "classes/*"
if ($ntp_servers) {
$servers = $ntp_servers
} else {
$servers = ["0.rhel.pool.ntp.org", "1.rhel.pool.ntp.org",
"2.rhel.pool.ntp.org"]
notice("ntp: ntp_servers not set. Using red hat's by default.")
}
modules/manifests/ntp/classes/ntp.pp
class ntp {
package { "ntp":
ensure => installed;
}
service { "ntpd":
enable => true,
ensure => running,
subscribe => File["/etc/ntp.conf"];
}
# template iterates over values in $servers array
file { "/etc/ntp.conf":
ensure => file,
owner => "root",
group => "root",
mode => "644",
content => template("ntp/ntp.conf.erb");
}
}
And then in different classes [0] I set the ntp servers and include the
module like:
$ntp_servers = ["timeserver1.example.edu", "timeserver2.example.edu"]
include ntp
I often receive the error message "Failed to parse template
ntp/ntp.conf.erb: Could not find value for 'servers' at
/etc/puppet/modules/ntp/manifests/classes/ntp.pp:19 on node
foo.example.edu" or my own notice() from the manifest above during runs.
I tried moving setting $ntp_servers from a class into a node, but that
did not make a difference.
Can anyone point out what I'm doing wrong or why this approach won't
work? I've read quite a bit on variable scope on the mailing list and
wiki, but I could still be missing something. I'm running puppet 0.24.8
on RHEL5.
[0] I have various nodes defined by function (e.g. database server) that
inherit from a base node. One thing the base node does is check a fact
that returns the location of the client. It then includes a module with
the location-specific configuration, such as the ntp server.
