You can make use of parameterized classes:
class application::add($appname) {
path => '/var/${appname}',
...
}
Within your node definition you call the class with desired parameter:
node 'node1' {
class application::add { appname => 'app1' }
class application::add { appname => 'app3' }
}
Kind regards,
