Shark / powerdns-consul

PowerDNS connector for the Consul key value store

powerdns-consul

powerdns-consul is a utility written in Go that allows you to use the Consul key value store as a backend for PowerDNS through the Pipe backend.

Some of the PowerDNS-related code is inspired by mindreframer's work.

Usage

1. Customize the powerdns-consul.json.example configuration
2. Execute ./powerdns-consul -config=/path/to/powerdns-consul.json

• Set DEBUG=1 to make powerdns-consul print each request and response

Architecture

powerdns-consul implements the PowerDNS pipe backend protocol. It can use various key-value stores to query for DNS records. Supported key-value store backends are:

• Consul (tested against v0.7.0)
• etcd (tested against v3.0.14)

You can organize the data in the key-value store in two different ways (schemas):

• Flat schema (docs)
• SkyDNS schema (docs, this will be implemented in a future version)

Building

• Clone the repository in your $GOPATH/src/github.com/Shark/powerdns-consul
• Run go get ./...
• Run make

Testing

• Go tests: run make test
• End to end test
  • Run make end2end_test.
  • Requires a working Docker setup.
  • This test will build powerdns-consul and a Docker image with PowerDNS, Consul and powerdns-consul. It will then bootstrap the Consul key-value store and run some 'real world' tests against this setup using dig.
