custom script execution and sending output back to master

[kaustubh chaudhari]

Hi All,

I am looking to run a shell script on the agent, i know there are many ways to to do that through manifests, customfacts etc.

What i want is, how to send output of this shell script or a file that is created by shell script back to master.

eg: i am running below script

==
#!bin/bash
cat /etc/issue > /tmp/test.txt
==

I want puppet agent to send this file or the output of the command # cat /etc/issue to the master?

Is this possible, if yes can some one suggest or redirect me to some docs that i can refer too.

Thanks in advance!

Cheers
Kaustubh

That requirement is practically the verbatim definition of External Facts.

Thanks for the reply Felix,

I was wondering if we can get the output of a executable custom fact to a specific-seperate file instead of standard servername.yml file ?

Hi,

I'm at a loss to what you are referring here, specifically. What is that
servername.yml you speak of?

If you want a custom fact to cache its value in some file, then modify
it to store the value there.

HTH,

Hey,

Thanks for the reply. I tried what you suggested.

Sorry i am not a programmer, trying to find my way through.

I am looking for a best way to achieve this.

run a script on nodes user.sh which will create a file user.out, all i am looking for getting this user.out file back to the puppet master.

can you suggest any ideas thoughts on this ?

(i am running user.sh through my manifest)

It should be as simple as this custom fact:

Facter.add('user_sh_output') do
setcode do
File.read('/path/to/user.out')
end
end

https://docs.puppetlabs.com/facter/2.1/custom_facts.html#loading-custom-facts

This documentation explains what is what and where to put the code.

HTH,
Felix

Cool!!! Thanks for that Felix. It did what i was looking for.

The only catch was formatting of the file is messed, but i did some scripting on the master server and fixed it.

Thanks for your help .....

more i work with puppet.. more i fell in love with it!!!
