A same class/module/orwhateveritis multiple times

Question

Puppet must hate me. I have been reading the doc for hours on end and still cannot manage to achieve the following:

• a class or module (or what is it called) with a variable in it (a parameterized class?);
• this class to be included multiple times in a single host.

In pseudo-code, that would be:

# The class
classorwhatever myclass ($value) {
    notify { "$value world" }
}

# In the node definition
node whatever {
    myclass("Hello")
    myclass("Goodbye")
}

I feel so stupid it is not even funny. I know it must be doable. But how? :(

You can only use a parameterized class once. If you plan to hit a node several times with a function while varying the data definitions are the way to go.

example

class apache ( $module ) {
  if module = ssl then and so on
}

define apache::vhost ($priority=99) {
  file { "apache/vhost.d/${name}":
    content => template("apache/vhosts/$name.erb"),
  }
}

node webserver {
  class { 'apache': module => 'ssl', }
  apache::vhost { 'www': priority => 00, }
  apache::vhost { 'test': priority => 99, } 
}
