not possible to access parameters from subclass

[Jens Kuehnel]

Hi all,

I'm using puppet for quite some time - about 10 years - but now I have a
problem that I can not fix.
I hope someone here can help me. I tried to google the problem, but the
solutions I found did not work.
The things that I tried are still in as a comment.

I have created a puppet modul that should be updated to include a config
class (normaly called a params class).

I simplified my setup and attached it at the end.

In the class servicea I tried to access the variable from the config
class, but I'm apparently not able to.

Can someone help me?

I case it is important I'm running Orcharhino 6.1. The Puppet-agent is
puppet-agent-6.28.0-1.el8.x86_64.

The output of puppet agent -t is:
Notice: In Config the servertype is: Frontend-Server
Notice: /Stage[main]/Testa/Testa::Config[config]/Notify[In Config the
servertype is: Frontend-Server]/message: defined 'message' as 'In Config

Notice: In Config the cluster_name is: mycluster

So you see that the variable is available from the config class, but
only the variable from init.pp is still accessible from the serivea
class. From the config class the variable is not avilable.

Thanks for any hints in advanced

This are the classes

# File init.pp
class testa (
$config = '',
$servertype = '',
) {
create_resources(testa::config, $config)
}

# File config.pp
define testa::config (
$cluster_name = '',
) {
# include testa
$servertype = $testa::servertype
notify{"In Config the servertype is: ${servertype}": }
notify{"In Config the cluster_name is: ${cluster_name}": }
include testa::servicea
}


# File servicea.pp
class testa::servicea {
#include testa::config
#Class[testa::config] -> Class[testa::servicea]
$servicea_cluster_name = $testa::config::servicea_cluster_name

notify{"In servicea the servertype is : ${testa::servertype}": }

notify{"in servicea the servicea_servicea are 1:
${::testa::config::servicea_servicea}": }
notify{"in servicea the servicea_servicea are 2:
${testa::config::servicea_servicea}": }
notify{"in servicea the servicea_servicea are 3:
${testa::servicea_servicea}": }
notify{"in servicea the servicea_servicea are 4: ${servicea_servicea}": }
}

Hi,

The testa::config manifests does not contain a class, but a defined resource types.
One can only access variables from included classes, but not from defined types.

Hth,
Martin
