Puppet users - Jul 2012 - Weird "cannot reassign variable name on node" error when I try to use standalone

Hi -- I''m trying call apply in standalone mode on a configuration
I''ve
written.
The way I call the command is like this:
  $ puppet apply manifests/site.pp -v --modulepath modules

The directory structure is simple:
  .
  manifests/site.pp
  manifests/nodes.pp
  modules/ ...

site.pp just includes nodes.pp, and nodes.pp looks like this:
https://gist.github.com/3181007

When I comment out the node declaration, it all compiles just fine, but
with the node declaration, I get this error:
  Cannot reassign variable name on node
ip-xx-xx-xx-xx.eu-west-1.compute.internal

Obviously, the node''s name in the original doesn''t have
''xx''s, but a valid
IP.

Can anybody advise me as to how to get this working? I''ve tried
everything
I can think of.
Thanks very much for any & all assistance,
   Doug.

The problem is in one of the classes declared by class
''imageserver'', not
in nodes.pp itself.  When you comment out the node declaration, no resource 
declarations remain for any node, so of course there is no error.

You didn''t say anything about the classes declared by class
''imageserver'',
so I can''t be more specific than that.  If I were to take a wild guess,
however, it would be that somewhere in there you have a defined type that 
attempts to assign a value to a local variable $name.  The variable names 
"name" and "title" are reserved inside defined types; for
each instance,
they are pre-assigned to the resource title, and like all puppet variables, 
their values cannot be reassigned.

Hmm.  I just realized that you are using Puppet in "apply" mode rather
than
"agent" mode.  The problem may simply be that puppet apply
doesn''t want to
handle node declarations.  I don''t use Puppet in "apply"
mode, so I''m not
sure, but node declarations don''t make much sense in that context.

Actually, your first answer was bang on the money -- thankyou ever so much
for that!
I''m now hacking through all the rest of the errors and typos to get it
all
running -- it''s maybe time I looked into the puppet test module!
Thanks again, that''s really appreciated,
   Doug.

Nah, node declarations work great with apply mode.  The use case is a 
little fuzzy, but let''s say you''re doing a whole standalone
site w/ puppet
apply being run out of cron. Node definitions would mean you still get the 
traditional benefit of only maintaining one codebase for many heterogeneous 
nodes, and then you just rsync the whole /etc/puppet directory around to 
every node. Every node would get a bunch of extraneous code it never uses, 
but assuming there''s no sensitive info in it, you probably
don''t mind.

(Apply mode can use an ENC too, come to think of it.)
