📚 go-powerdns - Awesome Go Library for Networking
PowerDNS API bindings for Golang.
Detailed Description of go-powerdns
PowerDNS 4.x API bindings for Golang
This community project provides bindings for PowerDNS Authoritative Server. It's not associated with the official PowerDNS product itself.
Features
Conveniently manage
It works entirely with the Go standard library and can easily be customized.1
For more features, consult our documentation.
Setup
go get -u github.com/joeig/go-powerdns/v3
import "github.com/joeig/go-powerdns/v3"
Usage
Initialize the handle
import (
"github.com/joeig/go-powerdns/v3"
"context"
)
// Let's say
// * PowerDNS Authoritative Server is listening on `http://localhost:80`,
// * the virtual host is `localhost` and
// * the API key is `apipw`.
pdns := powerdns.New("http://localhost:80", "localhost", powerdns.WithAPIKey("apipw"))
// All API interactions support a Go context, which allow you to pass cancellation signals and deadlines.
// If you don't need a context, `context.Background()` would be the right choice for the following examples.
// If you want to learn more about how context helps you to build reliable APIs, see: https://go.dev/blog/context
ctx := context.Background()
Migrate NewClient

If you have used NewClient
before and want to migrate to New

err := pdns.Records.Delete(ctx, "example.com", "www.example.com", powerdns.RRTypeA)
records, err := pdns.Records.Get(ctx, "example.com", "www.example.com", powerdns.RRTypePtr(powerdns.RRTypeA))
Request server information and statistics

servers, err := pdns.Servers.List(ctx)
server, err := pdns.Servers.Get(ctx, "localhost")
Handle DNSSEC cryptographic material
cryptokeys, err := pdns.Cryptokeys.List(ctx)
cryptokey, err := pdns.Cryptokeys.Get(ctx, "example.com", "1337")
err := pdns.Cryptokeys.Delete(ctx, "example.com", "1337")
Create/change/delete TSIG keys

tsigkey, err := pdns.TSIGKeys.Change(ctx, "examplekey.", powerdns.TSIGKey{Key: powerdns.String("newkey")})
tsigkeys, err := pdns.TSIGKeys.List(ctx)
tsigkey, err := pdns.TSIGKeys.Get(ctx, "examplekey.")
err := pdns.TSIGKeys.Delete(ctx, "examplekey.")

Requirements
Tested PowerDNS versions
Supported versions of PowerDNS Authoritative Server ("API v1"):
- 4.7
- 4.8
- 4.9
Version 4.1, 4.2 and 4.3 are probably working fine, but are officially end-of-life. Be aware that there are breaking changes in "API v1" between PowerDNS 3.x, 4.0 and 4.1.
Tested Go versions
In accordance with Go's version support policy, this module is being tested with the following Go releases:
- 1.22
- 1.23
Contribution
This API client has not been completed yet, so feel free to contribute. The OpenAPI specification is a good reference.
You can use Docker Compose to launch a PowerDNS authoritative server including a generic SQLite3 backend, DNSSEC support and some optional fixtures:
docker-compose -f docker-compose-v4.9.yml up
docker-compose -f docker-compose-v4.9.yml exec powerdns sh init_docker_fixtures.sh
It's also possible to target mocks against this server, or any other PowerDNS instance which is running on http://localhost:8080
.
make test-without-mocks
The mocks assume there is a vHost/Server ID called localhost
and API key apipw
.

There is a dependency for
