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 perfoming 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.

.. code-block:: ini

    webserver=yes
    api=yes
    api-key=changeme

2. Configure the PowerDNS Backend using this sample target snippet

.. literalinclude:: sample_yaml_snippets/pdns4.yaml
   :language: yaml

3. Then update the pools in designate

.. code-block:: console

    $ designate-manage pool update

See :ref:`designate_manage_pool` for further details on the ``designate-manage pool``
command, and :ref:`pools` for information about the yaml file syntax
