An interface with an external DNS service is defined for Neutron. A reference implementation is also included, based on Designate. The interface and the driver will enable users to publish in the external DNS service the dns_name and dns_domain attributes associated with floating ips, ports and networks. As a consequence, the floating ips and networks api is extended to manage dns_name and dns_domain attributes. The dns_name attribute was added to ports in a preceding commit DocImpact: Introduce config option external_dns_driver to specify a driver for external dns integration.

Integration with external DNS services
|
|
======================================
|
|
|
|
Since the Mitaka release, neutron has an interface defined to interact with an
|
|
external DNS service. This interface is based on an abstract driver that can be
|
|
used as the base class to implement concrete drivers to interact with various
|
|
DNS services. The reference implementation of such a driver integrates neutron
|
|
with
|
|
`OpenStack Designate <http://docs.openstack.org/developer/designate/index.html>`_.
|
|
|
|
This integration allows users to publish *dns_name* and *dns_domain*
|
|
attributes associated with floating IP addresses, ports, and networks in an
|
|
external DNS service.
|

|
Changes to the neutron API
|
|
--------------------------
|
|
|
|
To support integration with an external DNS service, the *dns_name* and
|
|
*dns_domain* attributes were added to floating ips, ports and networks. The
|
|
*dns_name* specifies the name to be associated with a corresponding IP address,
|
|
both of which will be published to an existing domain with the name
|
|
*dns_domain* in the external DNS service.
|
|
|
|
Specifically, floating ips, ports and networks are extended as follows:
|
|
|
|
* Floating ips have a *dns_name* and a *dns_domain* attribute.
|
|
* Ports have a *dns_name* attribute.
|
|
* Networks have a *dns_domain* attributes.
