[Puppet Users] Variable scoping question

[Bret Wortman]

I'm trying to improve my code reuse a bit, and I have some templates that 
all start with a common case statement to determine a local proxy (I'm 
simplifying the file slightly for our discussion here):

file: proxy.erb
<% proxy = case @site
   when "a" then "proxya"
   when "b" then "proxyb"
   when "c" then "proxyc"
   when "d" then "proxyd"
end -%>

This gets included in each template something like this:

file: CentOS-Base.repo.erb
<%= scope.function_template(["yum/proxy.erb"]) -%>
:
[base]
name=CentOS-$releasever - Base
:
<% if $proxy -%>
proxy=http://<%= $proxy %>:3128
<% end -%>
:

The problem is that the "proxy" variable isn't visible from the outer 
scope. How can I either qualify the outer reference to see it, or somehow 
export it? Is this possible in some other fashion? I don't want to repeat 
this code across all the various repo files; adding a proxy shouldn't mean 
editing every single repo file template when it could mean editing just one 
file that gets included somehow. At least, that's the goal.

Thanks!

[Puppet Users] Variable scoping question

Hi all,

I have a configuration similar to the following (the puppet version is
2.6.16):

node basenode {
$ldapenvironment = "office"
}
node mynode inherits basenode {
include ldap
}

class ldap {
file {
"/etc/openldap/ldap.conf":
owner => "root",
group => "root",
mode => 644,
source => [
"puppet:///modules/ldap/oldap.${ldapenvironment}.conf",
"puppet:///modules/ldap/oldap.conf",
],
sourceselect => first;

}

if ($operatingsystemmajorrelease == "6") {
include ldap::ldap-sssd
}
}

class ldap::ldap-sssd {
file {
"/etc/sssd/sssd.conf":
owner => "root",
group => "root",
mode  => 600,
source => 
"puppet:///modules/ldap/sssd.${ldapenvironment}.conf",
subscribe => Package["sssd"];
}
}


For the ldap class, things work as I expect, $ldapenvironment is
interpolated into the source. However, with the sub-class
ldap::ldap-sssd, the $ldapenvironment variable is empty and puppet
tries to fetch "sssd..conf".

Does variable scoping work differently in includes under node
definitions than under class definitions?

I could not find a good explanation for this in the docs, pointers
would be appreciated.
