puppet variables

Question

I am trying to use variables in my modules manifest.pp with little luck

class mysoftware($version="dev-2011.02.04b") {
  File {
    links => follow
  }

  file { "/opt/mysoftware":
    ensure => directory
  }
  file { "/opt/mysoftware/share":
    source => "puppet://puppet/mysoftware/air/$version",
    recurse => "true",
  }
  }

This does not seem to be working when I assign this to a node via the nodes.pp file.

I am running puppetmaster 2.6.4 puppetd clients are 0.25

Answer 1

I believe that you need to reference it like this:

source => "puppet://puppet/mysoftware/air/${version}",

Here's how I use something similar:

class aliases($al="aliases") {
    file { "/etc/aliases":
        mode  => 640,
        source => "puppet:///files/sendmail/${al}",
        owner => "root",
        group => "root",
        before  => Exec["create aliases db"]
    }

     exec { "new_aliases":
        command => "/usr/bin/newaliases",
        subscribe => File["/etc/aliases"],
        alias => "create aliases db",
        refreshonly => true,
     }
}

Which I reference from manifests/nodes.pp. I actually don't need to do it that way but set it up and tested it on your behalf (my other examples would have been much longer). Works like a charm.

Answer 2

Are you using 2.6 or older? Parameterized classes are new in 2.6, so if you're using an older version, this should not work.
