how to transfer list of interfaces from hiera to class

[Andreas Dvorak]

Hi,

I would like to create network interfaces with puppet.
I have
define network_interface::managed_interface(
  $device='',
  $gateway='',
  $hostname='',
  $hwaddr='',
  $ipaddr='',
  $netmask='',
  $network='',
  $up=true,
){

and
class network_interface::create_interface (
  $device = hiera(....)',
){
  managed_interface { $device:
    device  => $device,
    ipaddr  => $ipaddr,
    netmask => $netmask,
  }
}

and hiera yaml file:
network_interface:
  eth0:
    ipaddr: 10.112.67.40
    netmask: 255.255.0.0
  eth1:
    ipaddr: 10.15.67.40
    netmask: 255.255.0.0

Now I don't know how to read the hiera values in the class network_interface::create_interface. The interface names can be different.
Can some please help me?

Best regards
Andreas

Dear all,

suddenly I found the solution:
network_interface::device_list:

  eth0:
    ipaddr: 10.112.67.40
    netmask: 255.255.0.0
  eth1:
    ipaddr: 10.15.67.40
    netmask: 255.255.0.0

class network_interface (
  $device_list={}
){
  create_resources('network_interface::managed_interface',$device_list,{})
}

define network_interface::managed_interface(
  $device=$title,

  $gateway='',
  $hostname='',
  $hwaddr='',
  $ipaddr='',
  $netmask='',
  $network='',
  $up=true,
){

Best regards
Andreas

Your other option if using the future parser is to use the each function and iterate around the hash like you would in any other language.

$interfaces = hiera('network_interfaces')

# https://docs.puppetlabs.com/references/latest/function.html#each

$interfaces.each { |$interface|

  managed_interface { $interface['device']:

    device  => $interface['name'],
    ipaddr  => $interface['ipaddr'],
    netmask => $interface['netmask'], 
  }

}
