ब्रह्मन् brahman

brahman (ब्रह्मन्)

It is written as an extendable library for building DNS Balancer/Server.
Running it is pretty simple:

• Start the brahman app
• Implement a socket server(using :gen_udp or netlink)
• Implement a handler function
• Call Brahman.Dns.Handler.handle/2

Overview

Querying

Aims to make it as easy as possible to build DNS LB/Server.

iex> packet = File.read!("test/packet_data/dns_query.raw")
iex> handler_fn = &IO.inspect/1
iex> Brahman.Dns.Handler.handle(packet, handler_fn)

The handler_fn is a higher order function or form of {function(), [:args]}.

Zone Interfaces

• Brahman.Dns.Zones.put/2

  name = "example.com"
  
  records = [
    %{
      name: "dummy1.example.com",
      type: "A",
      ttl: 3600,
      data: %{ip: "192.168.5.1"}
    },
    %{
      name: "dummy2.example.com",
      type: "A",
      ttl: 3600,
      data: %{ip: "192.168.5.2"}
    },
    %{
      name: "dummy3.example.com",
      type: "A",
      ttl: 3600,
      data: %{ip: "192.168.5.3"}
    }
  ]
  
  :ok = Brahman.Dns.Zones.put(name, records)

• Brahman.Dns.Zones.get/1

  ^records = Brahman.Dns.Zones.get("example.com")

• Brahman.Dns.Zones.delete/1

  :ok = Brahman.Dns.Zones.delete("example.com")
  [] = Brahman.Dns.Zones.get("example.com")
