gathering instances of another type in a type.

[Steve Neuharth]

I'm writing a module to configure Oracle Weblogic (against my will).

I've created a type to handle the configuration of the config.xml file for the domain. In puppet, you'd use it like this:

  weblogic_domain{ $name:
    admin_server => $admin_server,
    domains_dir  => $domains_dir,
    require      => Exec["creating admin server for ${domain}"]
  }

so that's great... If i change my $admin_server, then my type changes admin_server in config.xml.

I'm having a bit of trouble, however, with the next part. A 'domain' in weblogic contains 'servers'... basically a hostname and port. I *could* do this:

  weblogic_domain{ $name:
    admin_server => $admin_server,
    domains_dir  => $domains_dir,
    servers          => $hash_of_servers_and_ports
    require      => Exec["creating admin server for ${domain}"]
  }

but what I'd really like to do is on each server, declare something like this:

  @weblogic_server{ $name:
    domain => myDomain
    port => 8000
  }

and then have my type gather up all the virtual resources and drop them into the server.xml automagically.

SO... how do I access the instances of one type from a different type? Can it be done? I've read the O'Reilly book on Types/Providers, skimmed a couple other books and scoured github for an example of this but I've come up with nothing.

please sir, a tuppence for a clue

This is pretty much exactly what datacat_collector does with its
datacat_fragment resources, so I think you'll find your answer if you
look at its code (or simply rework your stuff in terms of that)

fragments = resource.catalog.resources.find_all do |r|

r.is_a?(Puppet::Type.type(:datacat_fragment)) && ((our_names & [ r[:target] ].flatten).size > 0)

end

that's the nugget I was looking for. I think that should work very nicely.

Thank you very much,

Could you share the module on github ?

Thanks
