DNS service overview
|
|
====================
|
|
|
|
The DNS service provides DNS Zone and RecordSet management for OpenStack
|
|
clouds. The DNS Service includes a REST API, a command-line client, and a
|
|
Horizon Dashboard plugin.
|
|
|
|
The DNS service consists of the following components:
|
|
|
|
``openstack`` command-line client plugin
|
|
A plugin for the OpenStack Client CLI that communicates with the REST API
|
|
|
|
``designate-api`` component
|
|
An OpenStack-native REST API that processes API requests by sending
|
|
them to the ``designate-central`` over Remote Procedure Call (RPC).
|
|
|
|
``designate-central`` component
|
|
Orchestrates the creation, deletion and update of Zones and RecordSets.
|
|
|
|
``designate-producer`` component
|
|
Orchestrates periodic tasks that are run by designate.
|
|
|
|
``designate-worker`` component
|
|
Is a generic task runner, that runs both zone create / update and deletes,
|
|
and periodic tasks, from ``designate-producer``
|
|
|
|
``designate-mdns`` component
|
|
A small DNS Server that is responsible for pushing DNS Zone information to
|
|
the customer facing DNS Servers. Can also pull in DNS information about
|
|
DNS Zones hosted outside of the Designate infrastructure
|
|
|
|
``designate-agent`` component
|
|
A small python daemon that can be used for a limited sub set of DNS Servers
|
|
Some DNS Servers requrire commands be run locally, and to do this we use
|
|
this component.
|
|
|
|
.. note:: The majority of the DNS service installs will not need this
|
|
component.
|
|
|
|
``Customer Facing DNS Servers``
|
|
Serves DNS requests to end users. They are orchestreated by the
|
|
``designate-worker``, and the supported list is maintained
|
|
:ref:`here <driver_matrix>`.
