Puppet users - Nov 2012 - check if if file exists on client an master

Hi pupper community,

I am working with puppet on Windows and have an issue.
I want to check what version of a package is installed.
My idea was to add a file in the package package28112012.txt and while 
running the manifest check if that package28112012.txt exists on the agent?
Can I define a variable reading this filename on the master?

Regards and thanks in advance,

Romain

I think you would want to create a fact that publish that state to the
master.

there is what i tried:

# getpfoleproxyver.rb
#
Facter.add(:getpfoleproxyver) do
  setcode do
      Facter::Util::Resolution.exec(''basename `ls 
/softw4pc/Misc/pfoleproxy/pfoleproxy*.txt`'')
  end
end

the fact is working fine, but how to use this in my manifest?
i tried a lot but it was always empty?

$getpfoleproxyver should be correct, no?

Are you sure it''s working on the client? You can see the value when you
type facter -p | grep getpfoleproxyver

?

The facter should be executed on the server instead on the client.

Romain, I am confused.

In your first post you said you need to check if a package exists on the 
"Agent", the Puppet client.

Now below you say you need the check executed on the Master.

Facts are executed on the Agents and only ever on Agents. If you want to 
check for something on a client/agent machine, you use a Fact, like the one 
you posted below.

If you want to execute arbitrary code on the Master (during catalogue 
compilation) probably the simplest thing you are after is the Generate 
function:

http://docs.puppetlabs.com/references/latest/function.html#generate

On linux, I would use something that looks a bit like this:

class woof {
  $file_exists = generate(''/bin/test'', ''-f'',
''/softw4pc/Misc/pfoleproxy/pfoleproxy*.txt'')
  if $file_exists {
  ...
  }
}

There are other ways you can execute arbitrary code, like embedded Ruby 
with the inline_template() function, pure Ruby manifests, or bury the code 
somehow in a custom type and provider.

Does that help?

Hi,

I malformed my question.
This is a hint in the right direction.
