How to read the files of puppet agent.

[shashank sinha]

Hi,

I have written a code on template to open & read file i.e passwd but it reads the file from the puppet server (Master-node) rather I want to read the file of each agent-nodes.

Is it possible to read files from the agent node or to copy the files from agent to master?

Thanks

Shashank,

The templates are compiled on the master but can incorporate data sent to it from several sources, such as built-in facts, custom facts and exported resources. Copying files from node to master isn't possible in the manner that you want.

I suppose in this case setting a custom fact is the easiest solution. You can create a custom fact in various ways. They can be simple hardcoded files on the node, or run a simple or complex program on the node to determine the desired value. In your case a simple script that reads a file on the agent node and outputs a fact would be easy. Check out the following docs for info and examples:

• http://docs.puppetlabs.com/facter/2.0/custom_facts.html
• http://docs.puppetlabs.com/facter/2.0/fact_overview.html
  

You could also look at Exported Resources (http://docs.puppetlabs.com/guides/exported_resources.html) which will 'share' actual Puppet resources between nodes. Kind of hard to explain, so check the Nagios example in the doc.

Hope this helps,
Martijn

Hi Martijn,

Thanks for the suggestion.

Just now I have implemented the custom facts as you have suggested and its exactly meets the requirement.

Thanks
