Puppet users - Aug 2012 - Declare the same resource with different parameters

Hi all,

I''m developing  my own module, and i want to declare same resources in 
different class like this :

This resource is used to configure my Jboss server by copying conf files in 
/myappbase/applis/conf
class srhjboss::config::applis {

file { "/myappbase/applis/conf":

ensure => directory,
notify => Class[''srhjboss::service''],
recurse => true,
source => ''puppet:///modules/srhjboss/communs'',

}

}

The second class and resource is used to deploy the conf file of my war 
application like this :

class srhdeployit::war {

file { "/myappbase/applis/conf"'':
ensure => present,
source => "puppet://puppet/srnrepo/myappname",
recurse => true,
}

}

then i include the class in the node

node default {
   include srhjboss::config::applis
   include srhdeployit::war

I got the exact failure : 

err: Failed to apply catalog: Cannot alias File[ '' '' ] to 
["/sirhen/applis/conf"] at 
/etc/puppet/modules/srhjboss/manifests/config/applis.pp:47; resource 
["File", "/sirhen/applis/conf"] already declared at 
/etc/puppet/modules/srhdeployit/manifests/war.pp:44

Do you have suggestions on how to do it?

Thanks

Short version: use a define.

http://docs.puppetlabs.com/guides/language_guide.html#defined-resource-types


But did you mean to have unbalanced quotes here? There''s an extra
single quote.

file { "/myappbase/applis/conf"'':


Regardless of whether you use a define or a class, you can''t define the
same file resource twice.

In the first resource, this:

/myappbase/applis/conf

Will end up with the contents of:

puppet:///modules/srhjboss/communs

And in the second one, it will end up with these contents:

puppet://puppet/srnrepo/myappname

You''ll have to pick one per node.

Yes I want to fill  /myappbase/applis/conf with the content of twice 
sources, but in different class.

As Christopher explained, you cannot declare the same resource twice on the 
same node, as it is internally inconsistent.  You give Puppet conflicting 
information about the properties of the resource, so which is it supposed 
to apply?

Supposing that none of the files provided by class
''srhdeployit::war''
replace files provided by class ''srhjboss::config::applis'',
you should be
able to solve the problem by using separate File resources for each file or 
directory that the former wants to manage.  Note also that it looks like 
you probably need a ''requires'' parameter on the
''srhdeployit::war'' file(s).
