How to iterate over an array in Puppet

Question

I would like to iterate over an array that is stored as a Facter fact, and for each element of the array create a new system user and a directory, and finally make API calls

Answer 1

As of puppet 3.2 this is possible using the "future" parser like so:

$my_env = [ 'shared1', 'shared2', 'shared3', ]
each($my_env) |$value| {
  file { "/var/tmp/$value":
    ensure => directory,
    mode => 0600,
  }
  user { $value:
    ensure -> present,
  }
}
