pdns-cassandra

Remote backend backend for PowerDNS that talks to Cassandra

Getting started

Create Cassandra schema with cqlsh (tested with Cassandra 2.0.8):

CREATE KEYSPACE powerdns WITH replication = {
    'class': 'SimpleStrategy',
    'replication_factor': '3'
};

USE dns;

CREATE TABLE domain_metadata (
    name ascii,
    kind ascii,
    content ascii,
    PRIMARY KEY (name, kind)
);

CREATE TABLE domains (
    zone ascii,
    kind ascii,
    masters list<ascii>,
    PRIMARY KEY (zone)
);

CREATE TABLE records (
    qname ascii,
    qtype ascii,
    content ascii,
    priority int,
    ttl int,
    PRIMARY KEY (qname, qtype, content)
);

CREATE TABLE supermasters (
    nameserver ascii,
    ip ascii,
    account ascii,
    PRIMARY KEY (nameserver, ip)
);

Make sure you have the Cassandra driver from Datastax installed: https://github.com/datastax/python-driver

The recommended way is to just:

$ pip install cassandra-driver

Configure the PowerDNS remote backend:

launch=remote
remote-connection-string=http:url=http://localhost:5000

Now start the application:

DEBUG=True CASSANDRA_NODES=10.0.0.1,10.0.0.2 python pdns_cassandra.py
