[Puppet Users] resources from specific class only to apply to a node
Hi do I apply only one class to a node?
In my `site.pp'' file I am saying
puppet@sys-ubuntu:/etc/puppet$ cat manifests/site.pp
#site.pp
import "classes/*.pp"
node default { include nmc-delete }
But the node is also getting resources from other classes like `nmc''
notice: //Nmc::Myuser[tkimpto]/User[tkimpto]/ensure: created
Here is a list of classes
puppet@sys-ubuntu:/etc/puppet$ ls -1 manifests/classes/*.pp
manifests/classes/newungrp.pp
manifests/classes/newuthngrp.pp
manifests/classes/nmc2.pp
manifests/classes/nmc-delete.pp
manifests/classes/nmc.pp
manifests/classes/sudo.pp
How do I force a node to get resources only from one specific class
and do not look into others?

This works the same way in nodes."ok so using --tage classname works just fine. thanks a lot. learned something cool however, if I run the puppetd as a daemon, then I like to control this from the puppetmasterd. Is is possible to config a resource where a node will only get a specific class and nothing else?> > > > > -- > Nigel Kersten > nigelk@google.com > System Administrator > Google, Inc. > > > >-- Asif Iqbal PGP Key: 0xE62693C5 KeyServer: pgp.mit.edu A: Because it messes up the order in which people normally read text.

The classes specified by the chosen node spec (and only those) are applied to that client. That''s how it should be, and that''s how it works for me in version 0.24.8. I can think of several possible explanations for the behavior you see: 1) Your "nmc-delete" class includes other classes, which are therefore also applied to any node that gets nmc-delete. 2) You have another node spec somewhere (nodes.pp ?) that matches your client more closely than the default node spec, and you are getting the extra classes from there. 3) You are not talking to the puppetmaster you think you are talking to (e.g., test vs. production). There are surely other possibilities, but those seem the most likely to me.

If I''m reading your manifests correctly, your resources are not in classes at all. They are being applied [only] because you are importing them directly into site.pp. I think you need to structure your code something like this: class nmc-delete { define mygroup ($gid){ group { "$title": gid => "$gid", ensure => present, } } define deluser { exec { "/usr/sbin/userdel $name": } exec { "/usr/bin/rm -rf /export/home/$name": } } deluser { "seagate": } deluser { "abradley": } deluser { "bobrien": } } (And similarly for your other manifests.)
