curl output in variable using a function [closed]

updated 2016-11-29 15:04:26 -0600

I have a curl command as follows:

 curl -H "X-Token: token val" -X GET | jq -r .data.value

I would have to get the output from the above curl command and assign it to a variable in puppet, how do i do that?

I see that there is custom facts, generate command and custom functions. I am not sure which one to use and what is the difference between custom fact and custom function.

Also, the curl will be executed in the puppet agent node side, so i am not seeing generate as a best fit for this since in the docs it is mentioned it runs in the master. May be a ruby code for doing this ?

  $username1 = get_username($token, hiera(‘key1’))
  $password1 = get_password($token, hiera(‘key2’)) 
  $username2 = get_username($token, hiera(‘key3’))
  $password2 = get_password($token, hiera(‘key4’))

Please provide some examples, many thanks!

Here a very simple example.

cat ../lib/puppet/parser/functions/pw_retreiver.rb

require 'rest-client'
require 'json'
module Puppet::Parser::Functions
  newfunction(:pw_retreiver, :type => :rvalue) do |args|
    url = args[0]
    uri = args[1]
    res = RestClient.get(url + uri)
    data = JSON.parse(res.body)

Usage: [root@orc-app2 manifests]# grep -v "^#" init.pp

class m {
 $value = pw_retreiver('', '/users/1')

 notify { "Value:${value}": }



   [root@orc-app2 manifests]# puppet apply ../examples/init.pp 
    Notice: Compiled catalog for in environment production in 0.46 seconds
    Notice: Value:Leanne Graham
    Notice: /Stage[main]/M/Notify[Value:Leanne Graham]/message: defined 'message' as 'Value:Leanne Graham'
    Notice: Applied catalog in 0.01 seconds

Note: - No error checking - You need rest-client gem, if you're using PE you to install it with PE gem(/opt/puppetlabs/puppet/bin/gem) - You need to customise the args value to handle authentication - Actual data response of the url above can be view here
