I''ve got a generic user "java" that owns Java applications.
Due to
circumstances beyond my control, I cannot dictate a change here, so I need
to make Puppet work with the infrastructure on hand. The big problem,
though, is that java''s home directory varies with the application
that''s
being run. My thought for working around this was
class jboss {
include users
User["java"]{home => "/home/app1"
realize(User["java"])
}
where java is declared in
class users {
@user{"java": uid=500, gid=501}
}
Sadly, I get "err: Could not retrieve catalog from remote server: Error 400
on SERVER: Only subclasses can override parameters at
/var/puppet/src/modules/jboss/manifests/init.pp:23". Is there any way to
do
this that isn''t going to cause me severe pain? I suppose I can use a
define
for this particular account, but it seems ... stupid.

For your stated example the error means you need to use ''class jboss inherits users { }''[1]. This puts your Class[jboss] resources in the right scope so you can redefine existing resources from Class[users]. The existing ''include users'' will add that puppetclass, and resources, to your node but you aren''t in the correct scope to redefine them. You might also try #1088[2] style collections, with overrides[3]. I haven''t used these, but I think you''d do something like: class users { @user{ "java": uid => 500, gid => 500 } } class jboss { include users User <| name == "java" |> { home => "/home/app1" } } class notjboss { include users User <| name == "java" |> { home => "/home/app2" } } [1] http://docs.reductivelabs.com/guides/language_tutorial.html#classes [2] http://projects.puppetlabs.com/issues/1088 [3] http://docs.reductivelabs.com/guides/exported_resources.html -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Thanks. I''ll try that when I get in to the office tomorrow.

I''d recommend the following approach in you case:> class java { > user { java: ... } > } > > class jboss inherits java { > User[java] { home => "/home/jboss" } > } > > class tomcat inherits java { > User[java] { home => "/home/tomcat" } > }This will set the home of "java" to either of the two specified values, depending on which of the two classes jboss or tomcat you include. Including both leads to an error, keeping you from creating impossible configs. Best Regards, David -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
