Hi,
No, that is impossible to do. Once a class is declared it cannot be
undeclared. Puppet is an additive model.
The way that node inheritance works means you can *NOT* even do this:
class prod_scripts {
if ($actually_do_prod_scripts) {
...
...
}
}
node prod_base {
include prod_scripts
}
node server1 inherits prod_base {
$actually_do_prod_scripts = 1
}
... because $actually_do_prod_scripts is not defined when your prod_base
node declares your prod_scripts class.
Sorry to be the one to tell you, but when other people have asked about
what you are asking the reply is usually to redesign what you're trying
to do ;-)
Two ways forward:
Set all your variables in your nodes first, then at the last possible
moment you start to instantiate classes, this gets around the
inheritance model.
Redesign your modules and classes to be additive. If some nodes don't
need 'base_scripts' then it's not really appropriate in node 'prod_base'.
Hope that helps,
-Luke

Hi Team,
sorry for the delay. My setup is like this.
we have a 2 .pp file. one for production ( prod_base.pp) and
other for development ( dev_base.pp) under
/etc/puppet/manifests/nodes . we have included the respective
module in these 2 .pp files. for eg:
prod_base.pp has the below content
---------------------------------------------------
node prod_base {
# Prod Module
include prod_scripts
include prod_disabled_services
include prod_apache
}
--------------------------------------------------
now we also have a different .pp file for individual servers under
/etc/puppet/manifests/nodes by name servername.pp. for eg:
server1.pp, server2.pp etc.. content of the server1.pp file is as
below
-------------------------------------------------
node server1 inherits prod_base {
}
-------------------------------------------------
now server1 inherits all the module which is mentioned in
prod_base.pp.
now my requirements is to exclude some of the modules from
prod_base.pp for server server1.pp. How i can exclude certain
module from the inherited list?
Thanks,
Jeeva

Two comments: I think you are a bit impatient, and I think
there is insufficient detail/info to formulate an answer.
