As Patrick mentions, one solution i recommend is to enable storeconfigs and
have each node export a host entry for itself tagged with the tag you want
other hosts to collect.
For example, each node may export it's host entry with:
@@host { "$fqdn": ip_address => $ipaddress, tags => "webserver" }
The cluster may collect these resources to build the hosts file with:
Host <<|| tag == "webserver" ||>>
On my phone, so parameter names may not be perfect.
Hope this helps,

Take a look at http://docs.puppetlabs.com/guides/exported_resources.html. I
think this will give you what you want. *It will only work if you turn on
storeconfigs.*

Thanks for the feedback Jeff. Interesting feature that I had
unfortunately overlooked until now, but the basic question still
remains; how would I then generate specific hostfiles based on nodes
of the same tag? For instance, a web server to only have host entries
for items tagged webserver only, and not one large on-size-fits-all
file. Thanks,

Hello All,
Can someone point me in the right direction here. I'm trying to
create an erb template for my /etc/hosts file, so that when executed,
it populates the /etc/hosts file only with entries that are tag
relevant. For instance, if a server is tagged apache, only the apache
tagged entries would be populated into the /etc/hosts file. Thanks in
advance for you help.
I recommend using the built in host type to model and manage entries
in /etc/hosts rather than a template.
Modeling your configuration using a type rather than a file will allow
you to declare the resources as virtual, then simply realize them if
they're tagged with the tag you care about. In addition, you'll
receive a bunch of additional features "for free" like the
relationship graph, meta-parameters, reporting, etc...
For example:
class apache {
@host { "zaphod": ip => "1.2.3.4" }
}
# Realize host entries tagged with "apache"
Host <| tag == "apache" |>
