Puppet users - Jan 2011 - Passing node hostname to the Puppet managed node

Hi,

First of all, this is my very first message to this list, so please bear 
with me while I''m getting used to it.
Sorry for any non-standard way to ask a question here which I can be using 
without prior knowledgment.

I would like to be able to set up some config parameters on a given node 
which is going to be config-managed
by Puppet and, for various reasons, I would like to be able to set it''s
hostname on some node''s config files.

Is there any way I could make Puppet pass the node hostname via a 
manifest/class/whatever ? I know
thatone can use Facter''s variables into Puppet''s manifests (at
least I
recall reading about it somewhere)
but I was unable to actually get it working and I know that Facter does have 
hostname as one of the
available variables.

Any ideas ?

I believe you''re looking for templates.

http://docs.puppetlabs.com/guides/templating.html

As an example:

file { "/etc/hosts":
    content => template("hosts.erb")
}

And the template would contain this:

127.0.0.1  localhost
192.168.99.99  <%= hostname %> <%= fqdn %>

Hey, thanks for joining us.  We love to have new folks come in and
start using puppet. :)

Ben gave the syntax needed to use this in a template, but you should
be able to use either of the ''hostname'' or
''fqdn'' facts anywhere in
puppet when you run it.  If that isn''t working, it can help to post
the snippet of puppet code that is broken.  (Ideally, work out a
half-dozen lines that don''t work rather than your entire manifest,
that makes it easier to help you, but either way is fine.)

The reason for doing that is once, say, I have a copy of the manifest
I can test it on my machine and see if it works for me - or fix it, if
it doesn''t.  :)

Anyway, welcome to the list,
    Daniel

   I''ll give Ben''s suggestion a try once I get to my testing
environment again.
Thanks for the warm welcome. You guys rock :-)
