[![Hackage version](https://img.shields.io/hackage/v/pocket-dns.svg?style=flat)](https://hackage.haskell.org/package/pocket-dns)  [![Build Status](https://travis-ci.org/junjihashimoto/pocket-dns.png?branch=master)](https://travis-ci.org/junjihashimoto/pocket-dns)

PocketDNS is multi-backend (zookeeper and sqlite) DNS Server using persistent-library.

## Getting started

Install this from Hackage.

    cabal update && cabal install pocket-dns

When backend is zookeeper, conf.yml's format is below.

```
backend: zookeeper
coord: localhost:2181/
timeout: 300000
num-stripes: 1
idletime: 300000
max-resource: 30
```

When backend is sqlite, conf.yml's format is below.

```
