Description

This little Chef Cookbook provides recipes and definitions to install Splunk Forwarders and setup monitors for Splunk Storm.

As you know, Splunk Storm uses a proprietary credentials file to setup access to the Splunk Storm servers/account. You probably won't want to have this file floating around in your cookbook unencrypted, so we're going to stuff the contents of the credentials file into a Secure Databag.

To do that, you'll need to:

  1. Create the data bag using knife (or whatever process you usually take)

    knife data bag create licenses storm --secret-file ~/.chef/encrypted_data_bag_secret
    
  2. Open irb and run the following script (make sure you update the variables to suit your setup)

    require 'base64'
    require 'chef'
    
    data_bag     = "licenses"
    data_bag_key = "storm"
    license_file = "stormforwarder_XXXXXXXX.spl"
    
    Chef::Config.from_file("#{ENV['HOME']}/.chef/knife.rb")
    c = Chef::DataBagItem.load(data_bag, data_bag_key)
    
    contents = [File.open(license_file, "rb") {|io| io.read}].pack("m")
    c['data'] = contents
    c['filename'] = license_file
    
    c.save
    
  3. You'll probably want to check-in your databag into your SCM

    knife data bag show licenses storm -Fj > data_bags/licenses/storm.json
    

If you need to get the credentials out of the databag and into an actual file (note: the cookbook takes care of this for you), you can run this command in irb

require 'base64'
require 'chef'

data_bag     = "licenses"
data_bag_key = "storm"

Chef::Config.from_file("#{ENV['HOME']}/.chef/knife.rb")
c = Chef::DataBagItem.load(data_bag, data_bag_key)

File.open(c['filename'], "wb") do |file|
  file.write(c['data'].unpack('m').first)
end
