Today looking for a solution to this I came up with a nice solution. I know
this is old but I'm posting it just in case is useful for somebody:
on hiera.yaml:
:hierarchy:
- 'host/%{::domain}/%{::hostname}'
- 'domain/%{::domain}'
- 'role/%{system_role}'
- 'common'
on site.pp
node default {
$system_role = get_system_role()
}
and get_system_role is a custom function:
require 'yaml'
module Puppet::Parser::Functions
newfunction(:get_system_role, :type => :rvalue) do |args|
hostname = lookupvar('fqdn')
enc = %x[/etc/puppet/node.rb #{hostname}]
yaml = YAML::load enc
system_role = yaml['classes'].keys.first.scan(/::([a-z]*)/).flatten[0]
end
end
This is asuming you use an ENC to assign classes like foreman / cobbler or
pe
Cheers
Juan
