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.
The documentation is very unfortunately using Users as example for
virtual resources when in actuality they seldom need this extra
indirection. 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.
