Hiera and nested / reuse variables

[Helmut Schneider]

Hi,

common.yaml:

profiles:
mailserver:
postfix:
instances:
postfix-in:
instance_path: '/etc/postfix-in'
other_path: "%{instance_path}" <= required

Is it possible to nest both variables somehow? Or alternatively from
common.pp:

$instance_path =
$profiles['mailserver']['postfix']['instances'][postfix-in]['instance_pa
th']

Can I somehow use $instance_path from common.pp in common.yaml?

helmut@puppet:~$ sudo puppet agent -V
4.10.12
helmut@puppet:~$

Thank you!

common.yaml:

instance_path: '/etc/postfix-in'
profile:
mailserver:
postfix:
instances:
postfix-in:
instance_path: "%{hiera('instance_path')}"
other_path: "%{hiera('instance_path')}"

or, if you want to reuse value in the same file:

instance_path: &instance_path '/etc/postfix-in'
other_path: *instance_path

I don't think so. hiera is processed before catalog compilation.

I tried

profile:
mailserver:
postfix:
instances:
postfix-in:

instance_path: '/etc/posfix-in'
other_path:
"%{hiera('profile::mailserver::postifx::instances::postfix-in::instance_
path')}"

which gives an empty value.

This works but can I also construct a string here? Like

instance_path: &instance_path '/etc/postfix-in'
other_path: "*instance_path something_else"
