are there iterators and loops in puppet?

Question

When I define(?) a resource e.g. to ensure dir structure, are there any loops available?

Like that:

  for X in [app1,app2] do:
    file { \'/opt/app/         


        

Answer 1

As of version 3.2 there are lambdas

You must set parser = future in puppet.conf.

$a = [1,2,3]
each($a) |$value| { notice $value }

Another option for declaring multiple defined types is create_resources. Pass it a hash of hashes:

create_resources(file, {
 '/tmp/test1' => { 
      ensure => directory,
      owner  => 'root',
      group  => 'root',
      mode   => '0644',
    },  
 '/tmp/test2' => { 
      ensure => directory,
      owner  => 'www-data',
      group  => 'www-data',
      mode   => '0755',
    },  
})
