create_resource from a HoH

[Arnau]

Hi all,

I'm running hiera 1.3.1 and puppet 3.8.6.

I'd like to create resources based on some custom data structure. I'd like to group all data related to a tomcat instance in the same hash key in hiera:

cert/hostname.yaml

tomcatinst:

  instA:

    instance:

     server_control_port : '8001'

     http_port                  : '8011'

     ajp_port                   : '8111'

     ajp_params          :

       tomcatAuthentication : 'false'

     manage_firewall     : true

    warfile:

     path                : '/var/lib/tomcats/instaA/webapps/sample.war'

     owner               : tomcat

     group               : root

     source              : '/custom/sample.war'

InstA is the common key for the tomcat instance plus its warfile.  (Instance is a ::tomcat::instance resource and warfile is a file resource).

There is a main class that creates the tomcat instance + the warfile using a custom define (my_tomcat::instances)::

my_tomcat/init.pp

create_resources ('my_tomcat::instances', hiera_hash(tomcatinst))

* I need this define cause I'll be creating more than one insatnce per host.

The define where I called create_resource for the above resources (and here is where I have all the problems):

my_tomcat/instance.pp

define my_tomcat::instance (

  $instance  ='',

  $war        = '',

) {

$instance_hash={$name => $instance }

create_resource('::tomcat::instance', "$instance_hash")

$war_hash={$name => $war }

create_resource('file', "$war_hash")

Inside the define I don't have a hash that I can directly use in the creat_resource calls (such hash would make everything simple), $name is the key of the hash, and $name['insatnce'] and $name['warfile'] are the actual hashes that I must use for each resource. So, acording to my understanding, I must pass the hash { $name => $instance } and { $name => $war } to the create_resource function.

but it fails to create the resources. AFAIU it fails cause in puppet 3 the creation of hashes with variables as keys is not working ( I tried to use static values as keys and my code works). But it could be that I'm misunderstanding the whole thing :-) .

The workaround I'm implementing is a define that does not create resources with create_resources:

define my_tomcat::instances (

 $instance             = '',

 $war                  = '',

 $extra                = '',

) {

#create_resources('::tomcat::instance', "{$name => $instance}", $defaults)

tomcat::instance { "$name" :

    server_control_port  => $instance['server_control_port'],

    http_port            => $instance['http_port'],

    ajp_port             => $instance['ajp_port'],

    ajp_params           => $instance['ajp_params'],

    manage_firewall      => $instance['manage_firewall'],

}

#$mywars = hiera("my_tomcat::instances::$name::wars")

file { "$name" :

    path   => $war['path'],

    owner  => $war['owner'],

    group  => $war['group'],

    source => $war['source'],

}

which works as expected.

But I'm wondering if if there is way to use the create_resource function directy with the above HoH.

TIA,

Arnau
