Question

I have following manifest:

define foo($var) {
    file { $var: }
    $barclass::store += $var
}

class barclass {
    $store = []
    foo {
        "test1": var => "test1",
        "test2": var => "test2",
    }

    file { "myfile": content => template("puppet:///files/myfile.erb"); }
}

And following erb template:

<% store.each { |i| -%> 
<%= i + " " -%> 
<% } -%> 

My intention here is to collect all $var variables used as parameter of type foo. And provide them in myfile.erb template. In my example $store variable was used.

This example does not work. What have I wrong?

Is there better way to achieve same thing? I basically need to collect parameters used in some type and then provide them in some template.

You can’t access variables set in puppet manifests directly (only facter facts) – what you need is scope.lookupvar

scope.lookupvar('yourmodulename::barclass::store')

or just

scope.lookupvar('barclass::store')

if it’s not a module

SO

<% scope.lookupvar('barclass::store').each { |i| -%> 
<%= i + " " -%> 
<% } -%>
