Puppet users - May 2009 - Struggling to understand classes, nodes, and case statements

I am struggling with a multiple operating system Puppet setup.  My
Ubuntu client complains that "Configuration could not be instantiated"
and the warning message references a module that is for OpenSolaris
clients only (blastwave).

Please help me if you can.  I have been spinning my wheels for hours.

/etc/puppet/manifests/site.pp:

import "nodes"
import "templates"



/etc/puppet/manifests/templates.pp:

node basenode {
        case $operatingsystem {
                "Debian": { include baseapps }
                "Solaris": {
                        include automount, blastwave, ips, syslog,
timeslider
                }
        }
}

node default inherits basenode {}



/etc/puppet/manifests/nodes.pp:

node foo inherits basenode {
        include named::server, ntp::server
}

node bar inherits basenode {}

I think that the problem is that I have another case $operatingsystem
in the baseapps class that my basenode includes.  I don''t fully
understand why, but it seems to me that you can only use a variable
once.

That shouldn''t be the case.  Can you show us your full manifest? 
It''s
hard to trouble-shoot if we only see part of the manifest.

Thanks

James,

You are correct.  I misunderstood the problem I encountered.  Funny
enough my manifests are following your book almost verbatim.  :-)

My setup start working with a "case $operatingsystem" in templates.pp
and modules/sshd/manifests/init.pp.  Out of desperation I restarted
the server process.  Does the server require a restart to affect
changes to /etc/puppet/manifests/templates.pp?

If that isn''t it, I don''t know what fixed my problem, but I am
okay
now.

Regards,

Joe Kotran
