DNS Examples
============

Create an 'A' record for all your compute nodes
-----------------------------------------------

This example creates a new ``mydomain2.com`` zone at Zerigo and an A record
for all your Rackspace nodes. Value for the A record is the Node's first
public IP address.

.. literalinclude:: /examples/dns/create_a_record_for_all_rackspace_nodes.py
   :language: python

Create a record with a custom TTL
---------------------------------

This example shows how to create a record with a custom TTL. Keep in mind that
not all of the providers support setting a custom, per record TTL.

.. literalinclude:: /examples/dns/create_record_custom_ttl.py
   :language: python

Create a MX record and specify a priority
-----------------------------------------

Some record types such as ``MX`` and ``SRV`` allow you to specify priority. This
example shows how to do that.

.. literalinclude:: /examples/dns/create_record_with_priority.py
   :language: python

Create a CAA record
-------------------

.. note::

    Support for CAA record type has been introduced in Libcloud v3.1.0. At this
    point it has only been implemented and tested with CloudFlare and Gandii
    Live DNS drivers.

When creating a CAA record, data fields needs to be in the following format:
``<flags> <tag> <domain name / url>`` as shown below.

.. literalinclude:: /examples/dns/create_record_caa_record_type.py
   :language: python

Export Libcloud Zone to BIND zone format
----------------------------------------

.. note::

    This functionality is only available in Libcloud 0.14.0 and above.

This example shows how to export Libcloud Zone to bind format.

Keep in mind that generated bind zone file content doesn't contain ``SOA`` and
``NS`` records. This should work fine if you just want to import this file
using a DNS provider web interface, but if you want to use it with BIND you
need to manually add those records.
