MongoDB configuration for Bind9

This is just a simple hack in order to use MongoDB as database with a REST backend.

Install :

• Install libcurl-dev and json-c library
• Clone git://github.com/guillaumerose/bind-http-json.git
• Build as usual
• ./configure
• make
• make install
• Run named with following configuration and web server

Sample configuration :

controls { /* empty */ };

options {
  directory "/var/cache/bind";

  allow-transfer { any; };
  // auth-nxdomain no;
  listen-on-v6 { any; };
};

zone "example.com" {
  type master;
  database "remote http://127.0.0.1:4567";
};

Ruby server :

require 'rubygems'
require 'mongo'
require 'sinatra'

db = Mongo::Connection.new('flame.local.mongohq.com', 27078).db('development')
db.authenticate("***", "***")
coll = db.collection('data')

get '/example.com/lookup' do
  content_type "application/json"
  
  entry = coll.find_one({"name" =>  params[:name]})
  
  return '{}' if entry.nil?
  
  '{"type" : "' + entry['type'] + '", "field" : "' + entry['value'] + '"}'
end

get '/example.com/authority' do
  content_type "application/json"
  
  '{
      "data" : [
          {
              "type" : "SOA",
              "field" : [
                  "ns1.example.com.",
                  "dns.example.com.",
                  2010122701
              ]
          },
          {
              "type" : "NS",
              "field" : "ns1.example.com."
          },
          {
              "type" : "NS",
              "field" : "ns2.example.com."
          }
      ]
  }'
end

This server assumes that your document looks like { “name” : “www”, “type” : “A”, “value” : “192.168.0.1”}
