[Puppet Users] Access puppet hash name in templates

[Dan]

Hi,

I've defined a hash like so in my nodes.pp:

net::addr { "eth5":
rt => {
rt1 => {
address => '192.168.10.0',
netmask => '255.255.255.0',
gateway => '192.5.28.19',
src => '192.5.28.21'
},
}

What I can't get to access is the title of the hash in my templates, so I
want to print out the title of the hash i.e. "eth5", how can I do that?
Also I have a variable called $int in my define class in the file for my
module (/etc/puppet/modules/net/manifests/addr.pp), how can I access that
using the scope.lookupvar function from this template in the same module?

Thanks Dan

"eth5" is not the name/title of a hash, it is the title of a *resource* of
defined type 'net::addr'. That resource has a parameter 'rt' that is a
hash of hashes. Inside the resource, you can access the title as $title or
$name (either one). Inside a template evaluated by a template() or
inline_template() call from within the definition body, you should be able
to access it as @title or @name (and the hash as @rt).

Resources are not data objects for consumption by the catalog compiler
(except classes, inasmuch as those are sometimes cast as resources). You
should not attempt to use them as such. What you could do, however, would
be something along these lines:

class net {
$addresses = {
'eth5' => {
rt => {
rt1 => {
address => '192.168.10.0',
netmask => '255.255.255.0',
gateway => '192.5.28.19',
src => '192.5.28.21'
}
}
}
}
}

You can then access it as $net::addresses['eth5'] from Puppet DSL, and you
can use scope.lookupvar('net::addresses') to retrieve the hash, and then
access the value of its 'eth5' key.
