Examples

Basic initialization

import powerdns

PDNS_API = "https://my.pdns.api.domain.tld/api/v1"
PDNS_KEY = "mysupersecretbase64key"

api_client = powerdns.PDNSApiClient(api_endpoint=PDNS_API, api_key=PDNS_KEY)
api = powerdns.PDNSEndpoint(api_client)

Creation and deletion of zones

from datetime import date

# Creating new zone on first PowerDNS server
serial = date.today().strftime("%Y%m%d00")
soa = "ns0.domain.tld. admin.domain.tld. %s 28800 7200 604800 86400" % serial
soa_r = powerdns.RRSet(name='test.python-powerdns.domain.tld.',
                       rtype="SOA",
                       records=[(soa, False)],
                       ttl=86400)
zone = api.servers[0].create_zone(name="test.python-powerdns.domain.tld.",
                                  kind="Native",
                                  rrsets=[soa_r],
                                  nameservers=["ns1.domain.tld.",
                                               "ns2.domain.tld."])

# Getting new zone info
print(zone)
print(zone.details)

# Deleting newly created zone
api.servers[0].delete_zone(zone.name)

Creation and deletion of DNS records

zone = api.servers[0].get_zone("test.python-powerdns.domain.tld.")

comments = [powerdns.Comment("test comment", "admin")]

zone.create_records([
    powerdns.RRSet('a', 'A', [('1.1.1.1', False)], comments=comments),
    powerdns.RRSet('b', 'A', ['1.1.1.2', '1.1.1.3']),
    powerdns.RRSet('c', 'A', [('1.1.1.4', False)]),
    powerdns.RRSet('d', 'CNAME', ['a'])
])

zone.delete_records([
    powerdns.RRSet('a', 'A', [('1.1.1.1', False)]),
    powerdns.RRSet('d', 'CNAME', ['a'])
])

Where (for the first RRSet):

  • a is the NAME of the record
  • A is the TYPE of the record
  • [('1.1.1.1', False)] is a list of RDATA entries (tuples or just strings), where:
    • '1.1.1.1' is the RDATA
    • False tells that this RDATA entry is NOT disabled

Backup and restoration of zones

# Backup every zone of every PowerDNS server
for server in api.servers:
    backup_dir = "backups/%s" % server.id
    for zone in server.zones:
        zone.backup(backup_dir)

# Restore a single zone on first PowerDNS server
zone_file = "backups/pdns-server-01/my.domain.tld.json"
api.servers[0].restore_zone(zone_file)

Tests

PowerDNS service

A simple Dockerfile is provided to spawn a basic powerdns service for tests purposes. The container is built using:

docker build --tag pdns .

And started using:

docker run --rm -it pdns

Python Unit-Tests

Python unit-tests are available in the tests directory. Based on unittests, those are run using coverage run -m unittest discover or integrated in your IDE for development purposes. Those tests require a PDNS service to connect to (see PowerDNS service section above).

Those tests are very limited at the moment and will be improved in the future.
