PDNS4 Backend¶

PDNS4 Configuration¶

The version PowerDNS in Ubuntu Xenial is pdns4. This has a different DB schema, and is incompatible with the legacy PowerDNS driver. In PDNS 4 the API was marked stable, and this is what we will use.

You will need to configure PowerDNS, and its database before performing these steps.

You will need to use a database backend for PowerDNS’s API to function.

See PowerDNS Docs for details.

1. Enable the API in the pdns.conf file.

webserver=yes
api=yes
api-key=changeme

2. Configure the PowerDNS Backend using this sample target snippet

  targets:
    - type: pdns4
      description: PowerDNS4 DNS Server

      # List out the designate-mdns servers from which PowerDNS servers should
      # request zone transfers (AXFRs) from.
      masters:
        - host: 192.0.2.1
          port: 5354

      # PowerDNS Configuration options
      options:
        host: 192.0.2.1
        port: 53
        api_endpoint: http://127.0.0.1:8081
        api_token: changeme

3. Then update the pools in designate

$ designate-manage pool update

See designate-manage pool for further details on the designate-manage pool command, and DNS Server Pools for information about the yaml file syntax
