After a couple of try, i understood it.

for anyone looking at the same solution, my code:

manifest:
$masterenvpath = print_environmentpath()
$path = 
"${masterenvpath}/${::environment}/modules/braveconf/files/puppet/puppet.conf-${::hostname}"
if ( file_exists ("${path}") == 1 ) {

function:
lib/puppet/parser/functions/print_environmentpath.rb
require"puppet"
  module Puppet::Parser::Functions
newfunction(:print_environmentpath, :type => :rvalue) do |args|
Puppet.initialize_settings unless Puppet[:environmentpath]
path = Puppet[:environmentpath]
if File.exists?(path)
  path
else
  nil
end
  end
end


Thank you very much Martin!

Daniele

Re: [Puppet Users] environmentpath in manifest

Hi Michael,

there are 2 possibilities:
1) i have not got what you mean.

2) you have not got what i mean.

To better explain:
your suggestion is to look over a fact in the agents.
my needed environmentpath variable is the master one.
i need to check over the existence of a file, but i want to have the full path 
as variables.
in example: $confdir in puppet.conf, but master section, not agent one.

which of the 2 cases? :)

Thanks in any case!

Daniele

Re: [Puppet Users] environmentpath in manifest

[wattersmt]

You may need to create a custom fact to determine the environment when
the agent runs.  For example, here's a
custom fact that reads the environment from a file.

Facter.add("environment") do
   setcode do
 Facter::Util::Resolution.exec('/bin/cat /usr/local/etc/environment')
   end
end

Your site manifest can also be set to update the file contents when it runs.

Hi,

i need to check if a file exists on the puppet master.

No big deal:
http://stackoverflow.com/questions/18784329/how-to-test-for-existence-of-a-file-on-the-puppet-master

So i made:
--
cat ./modules/braveconf/lib/puppet/parser/functions/file_exists.rb
require"puppet"
   module Puppet::Parser::Functions
 newfunction(:file_exists, :type => :rvalue) do |args|
 if File.exists?(args[0])
   return 1
 else
   return 0
 end
   end
end
--

Now, my problem is about path.

Since i have environmentpath, as seen is
puppet config print  environmentpath --section master --environment development
/etc/puppetlabs/code/environments

I would like to use, in the manifest:
--
if ( file_exists 
("${::environmentpath}/${::environment}/modules/module/files/configfile-${::hostname}")
 == 1 ) {
--

But ${::environmentpath} is empty.

How can i manage this topic, avoiding to hardcode 
/etc/puppetlabs/code/environments in the code?
Is there a way to get variable from puppet master config?

Thanks,
Daniele

The Ruby part must be a function - like in the example you provided in your 
first email.
You can then use the function inside your manifest.

Functions are always executed on the Master.

Best,
Martin

Hi Martin,

Thank you very much for your hint.

But I am not able to understand how to write it.
How can I interlock between this ruby code and the manifest?

Sorry if this is a FAQ question :)
Do you have some link or example to understand how this should work?

Thank you very much,
Daniele

You might want to access the Puppet settings:

Puppet.initialize_settings unless Puppet[:confdir]

and then check for the environmentpath setting.
