Designate in Kolla
|
|
==================
|
|
|
|
Overview
|
|
========
|
|
Designate provides DNSaaS services for OpenStack:
|
|
|
|
- REST API for domain/record management
|
|
- Multi-tenant
|
|
- Integrated with Keystone for authentication
|
|
- Framework in place to integrate with Nova and Neutron
|
|
notifications (for auto-generated records)
|
|
- Support for PowerDNS and Bind9 out of the box
|
|
|
|
Configuration on Kolla deployment
|
|
---------------------------------
|
|
|
|
Enable Designate service in ``/etc/kolla/globals.yml``
|
|
|
|
.. code-block:: console
|
|
|
|
enable_designate: "yes"
|
|
|
|
Configure Designate options in ``/etc/kolla/globals.yml``
|
|
|
|
.. important::
|
|
|
|
Designate MDNS node requires the ``dns_interface`` to be reachable from
|
|
public network.
|
|
|
|
.. code-block:: console
|
|
|
|
dns_interface: "eth1"
|
|
designate_backend: "bind9"
|
|
designate_ns_record: "sample.openstack.org"
|
|
|
|
Neutron and Nova Integration
|
|
----------------------------
|
|
|
|
Create default Designate Zone for Neutron:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack zone create --email admin@sample.openstack.org sample.openstack.org.
|
|
|
|
Create designate-sink custom configuration folder:
|
|
|
|
.. code-block:: console
|
|
|
|
$ mkdir -p /etc/kolla/config/designate/designate-sink/
|
|
|
|
Append Designate Zone ID in ``/etc/kolla/config/designate/designate-sink.conf``
|
|
|
|
.. code-block:: console
|
|
|
|
[handler:nova_fixed]
|
|
zone_id = <ZONE_ID>
|
|
[handler:neutron_floatingip]
|
|
zone_id = <ZONE_ID>
|
|
|
|
Reconfigure Designate:
|
|
|
|
.. code-block:: console
|
|
|
|
$ kolla-ansible reconfigure -i <INVENTORY_FILE> --tags designate
|
|
|
|
Verify operation
|
|
----------------
|
|
|
|
List available networks:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack network list
|
|
|
|
Associate a domain to a network:
|
|
|
|
.. code-block:: console
|
|
|
|
$ neutron net-update <NETWORK_ID> --dns_domain sample.openstack.org.
|
|
|
|
Start an instance:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack server create \
|
|
--image cirros \
|
|
--flavor m1.tiny \
|
|
--key-name mykey \
|
|
--nic net-id=${NETWORK_ID} \
|
|
my-vm
|
|
|
|
Check DNS records in Designate:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack recordset list sample.openstack.org.

Query instance DNS information to Designate ``dns_interface`` IP address:
|
|
|
|
.. code-block:: console
|
|
|
|
$ dig +short -p 5354 @<DNS_INTERFACE_IP> my-vm.sample.openstack.org. A
