Puppet users - Oct 2013 - require one file from several environments

I would like to create one file with array, i.e.:

$pkg_versions = {
  soft1  => { prod => "0.0.6", test => "0.0.7" },
  soft2 => { prod => "1.1.4", test => "1.1.5" };
}

And "require" this file in several environments.

I tried to use "require /var/lib/puppet/somedir/etc/file.inc", but
puppet
can not find it.

What solution should I use? Or maybe is it possible to put this array in 
puppet class, include it in parent classe and get its values?

Thanks for help!

Data like this should probably go into hiera. Then write modules to
use the data via parameterized classes or hiera() lookups.  For
example we use the "datadir" directive in hiera to split out hiera
lookups to become environments aware.  This would simplify your data
structure to where you are just specifying the data for each
environment to use instead of having to code your manifests to
understand the data structure in a environmentally aware state.

Example in your prod environment hiera yaml:
software::soft1::version: 0.0.6

Example in your test environment hiera yaml:
software::soft1::version: 0.0.7

Then in your class:
class software::soft1($version) {
  package { ''soft1'':
    ensure => $version
}

Hiera would give your puppet clients the correct answer based on environment...

However if you just want to use your data structure you referenced
above you can place it into a module/class or even use import. However
importing in a file like site.pp is not really recommended for various
reasons.

Puppet does not provide a mechanism for interpolating DSL files.  The 
closest it comes is the ''import'' feature, but that
doesn''t do quite what
you''re looking for; in fact, it has approximately one good use case.

The ''require'' function you are trying to use is a specialized
version of
the ''include'' function, both of which ensure that the named
*class* is
included in the target node''s catalog.  Although that can trigger the 
autoloader to try to load a file it expects to contain the definition of 
the named class, that''s basically a side effect.

You can absolutely put it in a class, or even put it at top level in 
site.pp.  Puppet does not provide for data hiding, so you do not need to 
inherit from the data''s host class to have access to the data.  This
would
work, for example:

<module_path>/site/manifests/versions.pp
----
class site::versions {
  $pkg_versions = {
    soft1 => { prod => "0.0.6", test => "0.0.7" },
    soft2 => { prod => "1.1.4", test => "1.1.5" };
  }
}

<module_path>/soft1/manifests/init.pp
----
class soft1 {
  # ensure that site::versions is evaluated so that
  # its variables are available
  include site::versions.pp
  $soft1_versions = $site::pkg_versions[''soft1'']
  $my_version = $soft1_versions[$::environment]
  # ...
}

With all that said, however, I have to agree with Cory that this sort of 
problem is very well served by hiera, whether you actually use hiera 
automatically, as he demonstrates, or via explicit calls to the hiera() 
function.  If you have only this particular problem to solve then it might 
not be worth setting up and learning Hiera, but in truth, you''re likely
to
run into more such problems in the future.

Sorry, that should be

$soft1_versions = $site::versions::pkg_versions[''soft1'']

Thanks! That is what I need.
