[Puppet Users] new user - understanding arrays as variables in defined types

[Dusty Doris]

Lets say I wanted to make a declared type for adding custom firewall rules 
on a per-node basis.


define myfirewall::accept($proto, $port, $sources=[]) {
  include defaultfirewall

  $sources.each do |source|
    
    firewall { "100 allow $proto $port for $source":
      proto  => $proto,
      dport => $dport,
      source => $source,
      action   => 'accept',
    }

  end
}

I could use it something like this:

node "mynode" {
  myfirewall:: accept { "http": 
    proto => 'tcp',
    port   => '80',
    sources => ['1.1.1.1','2.2.2.2']
  }
}


Is there any way to do something like this with puppet?  I'm new to this 
and quite confused.
