[chef] Databags parsing and templates

[Philippe Bérard < >]

I think I’ve a quite simple question for experts here, but this one’s driving me mad as there are only a very few examples on how to use databags with templates on the Web.

 

I have a databag on my CHEF server, named “instances” and organized like this :

owner : nobody

id : instances

type : dbapp {

                Java_webapp

               Tomcat

}

webapps : {

_default {

                port : “8001”

                name : “preprod1.test.com”

}

                testjava {

                port : “8002”

                name : “preprodjava.test.com”

}

                Testtomcat {

                port “8003”

                name : “preprodtomcat.test.com”

}

}

 

A template :

è /templates/default/test.conf.erb :

# Set up application listeners here.

worker.list = jkstatus

 

# Test configuration

 

<% @server.each do |server, port| %>

<%= server %>, <%= port %>

<% end %>

 

And my recipe to generate a proper configuration file :

è /recipes/default.rb

#

# Cookbook Name:: testdatabag

# Recipe:: default

#

# Copyright 2012, TEST

#

# All rights reserved - Do Not Redistribute

#

require 'chef/data_bag'

 

server=[]

port=[]

 

data_bag(‘instances’).each do |webapps|

    s = data_bag_item(‘instances’,'webapps')

    server << s['name']

    port << s['port']

end

 

 

template "test.conf" do

  path "/tmp/test.conf"

  source "test.conf.erb"

  owner "root"

  group "root"

  mode "0644"

  variables(

                :server => server,

                :port => port

)

 

My result should be :

# Test configuration

preprod1.test.com, 8001

preprodjava.test.com, 8002

preprodtomcat.test.com, 8003

 

And, well, it doesn’t work at all.

 

Thanks in advance for any help or hint.
