Issue #2269 has been updated by Luke Kanies.

Status changed from Needs design decision to Rejected

Yeah, this behaviour definitely belongs in the external node tool.  Puppetrun 
can even talk to ldap, getting node group information (classes are essentially 
node groups).

Feature #2269: Node list feature

Hi,

I would like to see a feature to define a list of nodes in Puppet.
As far as I understand, we can currently define multiple nodes like this:

node server1, server2, server3 {
include someresource
}

This wouldn't scale very well with puppetrun, because I would have to use 
something like:
sudo puppetrun --host server1 --host server2 --host server3
where the number of nodes could be 100.

Instead, I would like to have a node list like this:
nodelist servergroup1 {
server1,
server2,
server3
include resources
}

and I can puppetrun this with
puppetrun --nodelist servergroup1

A feature to group nodes together adds a layer of abstraction in node 
management.  It's very common to want to group similar nodes (i.e. servers 
under a single load-balancer) and be able to apply the same configuration in 
one shot, without having to go through each node definition and update 
appropriate resources.

If there is already a way to do this, my apologies for not knowing puppet 
enough. As far as I have asked around on IRC #puppet, people only pointed me to 
listing multiple hosts in one line like I described here.
