Puppet users - Jun 2007 - can i access module "files" w/o using client-server?

Hi,

I''m new to puppet and trying to get started using it just in local
mode.
My basic question is: how can i reference a static file within the module
(eg in the module''s files/ subdirectory, as described in
http://reductivelabs.com/trac/puppet/wiki/ModuleOrganisation).  I suppose i
could try using a full.absolute path to the file, but that seems to
completely defeat the purpose of a module.

I overcame my first hurdle - which was getting puppet to find the module at
all.  I created a puppet.conf containing a modulepath declaration.  At this
point, even without a fileserver.conf file at all, it seems like puppet
knows where my module is and should be able to find its files.

Here is my test setup
manifests/test.pp:
    import "testmod"
    include testmod

modules/testmod/manifests/init.pp
    class testmod {
        file { "/tmp/hithere.txt":
                ensure => present,
                source => "/testmod/hello.txt"
        }
    }

modules/testmod/files/hello.txt:
    hello world

puppet.conf:

modulepath=$confdir/modules:/usr/share/puppet/modules:/home/rich/puppet/modules

i run with the command:
    puppet test.pp
and get the output:
    notice: mount[localhost]: File source /testmod/hello.txt does not exist

I have tried numerous variations to no avail.  i have been reading the
puppet source code to try to understand how it works.  From what i gather,
here is what is happening:
    since the source of the file does not use the puppet: protocol, file: is
used, and pfile.rb forces @@localfileserver to a fileserver instance whose
only mount point is ''/''.  in particular, the modulepath is
ignored and no
configuration is read either.  (NOTE: i started playing around with a
fileserver.conf but found that the code specifically ignores it anyway)

Am i just being stupid here?  Can someone explain how to make this work?
Better yet, let me explain a bit more about what i really want and maybe
someone can suggest a better way :)  Basically, i''d like to create some
modules that include files to install.  So, my thinking is that i will copy
them to /tmp, so that i can subsequently refer to them using an absolute
path (/tmp/foo.zip, for example) in order to install them.  Is there a
better way?   Oh, and, yes, i expect to eventually move to a client-server
model, but prefer the simplicity (or so i thought!) of a completely local
setup, especially since at this point i don''t expect to run puppetd
daemon
on the client(s).


also, i''m interested in using this for systems running
nginx/mongrel/rails/mysql/monit/munin.  i''ve seen puppet recipes for
mysql
and munin (Thanks!), but if there are recipes available for the other parts
that somoene could point me to, i''d be most appreciative.  We are early
in
our development, so puppet is not ''necessary'' yet, but i
prefer having a
framework in place to build on from the start.

thanks
rich

I''ve just added my code stubs for setting up a Rails+Mongrel+Apache2 
+Proxybalancer -based railsstack. Feel free to take a look at it and  
comment back.

Looks like maybe there''s a bug using modules to find local files.   
Filed as a bug.

I guess I haven''t spent much time on the fileserver when used with  
puppet.  Clearly this is an oversight, and I''ve filed #658 (which was  
discussed a long time ago on the list) to help fix that oversight.
