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.  

```elixir

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`

  ```elixir

  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`

  ```elixir

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

  ```

- `Brahman.Dns.Zones.delete/1`

  ```elixir

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

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

  ```
