Hi,
I needed a function to check if a file is existing on the Debian box I
am configuring. So I used this one
module Puppet::Parser::Functions
newfunction(:file_exists, :type => :rvalue) do |args|
if File.exists?(args[0])
return 1
else
return 0
end
end
end
It work greats for some service where apache2 doesn''t work for me.
I am using it this way
"file_exists(''/etc/init.d/apache2'') == 1" if
this return true I will stop the service or do nothing.
In my case, the file /etc/init.d/apache2 exists on the puppet master
running through Passenger, but the puppet client doesn''t have it.
But when I run the puppetd -vt it returns me an error because it''s
thinking the file /etc/init.d/apache2 exists on the puppet client and
tries to stop the service.
do you have any idea, is there a caching system on puppet client where
we could delete a cached function?
Thank you!

Hi there, So, functions will ALWAYS be executed on the Puppet MASTER server. They''re never executed on the client. This is why you''re seeing the behavior that you do.

What is the purpose of running such function if they are not running on the client?

As Nigel said, custom FACTS will be run on the client side (only), and so you can create a custom fact that will give you what you need. Check out the documentation if you need some more help with that --> http://docs.puppetlabs.com/guides/custom_facts.html On Wed, Feb 22, 2012 at 12:27 PM, DRivard <dominick.rivard@gmail.com> wrote:> What is the purpose of running such function if they are not running > on the client? > > On Feb 22, 3:22 pm, Gary Larizza <g...@puppetlabs.com> wrote: > > Hi there, > > > > So, functions will ALWAYS be executed on the Puppet MASTER server. > They''re > > never executed on the client.
