Designate + Nova/Neutron

slide-25
SLIDE 25

What we are configuring

Database PowerDNS Backend Central API AMQP Keystone User Nova / Neutron Sink

slide-26
SLIDE 26

Designate Sink and Notification Handlers

  • Designate Sink consumes notification events from:

○ Nova ○ Neutron ○ possibly other services

  • Designate Sink turns events into DNS operations.
  • What events and what DNS operations are performed are determined by custom notification

handlers: ○ nova_fixed ○ neutron_floatingip

slide-27
SLIDE 27

Nova Configuration Changes

  • Enable notifications for Designate in nova.conf:

[DEFAULT] notification_driver = nova.openstack.common.notifier.rpc_notifier notification_topics = monitor notify_on_state_change = vm_and_task_state

slide-28
SLIDE 28

Neutron Configuration Changes

  • Enable notifications for Designate in neutron.conf:

[DEFAULT] notification_driver = neutron.openstack.common.notifier. rpc_notifier notification_topics = monitor

slide-29
SLIDE 29

Designate Configuration Changes

  • Enable Designate Sink in designate.conf:

[service:sink] enabled_notification_handlers = nova_fixed, neutron_floatingip

  • Enable Nova notification handler in designate.conf:

[handler:nova_fixed] domain_id = <random uuid> notification_topics = monitor control_exchange = 'nova' format = '%(display_name)s.%(domain)s'

slide-30
SLIDE 30

Designate Configuration Changes (continued)

  • Enable Neutron notification handler in designate.conf:

[handler:neutron_floatingip] domain_id = <random uuid> notification_topics = monitor control_exchange = 'neutron' format = '%(display_name)s.%(domain)s'

  • Restart Designate services:

○ sudo killall designate-api ○ sudo killall designate-central ○ sudo designate-central & ○ sudo designate-api &

  • Start Designate Sink service:

○ sudo designate-sink &

slide-31
SLIDE 31

Creating and Deleting VM

  • Setup the environment for the user1 user:

○ source openrc.user1

  • List the images:

○ nova image-list

  • List the flavors:

○ nova flavor-list

  • Create the VM instance:

○ nova boot testvm --image <image-id> --flavor <flavor-id> ○ nova list

  • Show the records:

○ designate domain-list ○ designate record-list <domain-id for example.com.> ○ dig @localhost testvm.example.com.

slide-32
SLIDE 32

Create and Delete VM (continued)

  • Delete the VM instance:

○ nova delete testvm ○ nova list

  • Show the records:

○ designate domain-list ○ designate record-list <domain-id for example.com.> ○ dig @localhost testvm.example.com.

Getting Involved - Bare Necessities

  • Get a good IRC client.. You’ll need it.

○ Join #openstack-dns and introduce yourself :)

  • Attend the weekly IRC meetings:

○ Wednesdays @ 17:00 UTC in #openstack-meeting-alt ○ Agenda - https://wiki.openstack.org/wiki/Meetings/Designate

  • File a bug/blueprint for your idea - Then add it to the agenda…

○ It’s OK to only have a rough sketch of the idea - that’s usually enough to begin discussions.

  • Sign the Contributors License Agreement
  • Get familiar with Gerrit - We can’t accept patches outside of Gerrit (Gerrit enforce the CLA)

Plugin Interfaces

Designate has several plugin interfaces, where replacement/additional implementations can be dropped in without the need to modify core code, these can even be provided by out of tree Python modules, avoiding the need to fork for private plugins.

  • New API v1 Endpoints (v2 will eventually be pluggable)
  • Storage Drivers (SQLAlchemy in the box)
  • Backend Drivers (PowerDNS, NSD4, FreeIPA, DynECT, BIND9 (kinda..))
  • Sink’s Notification Handlers

Full List: http://goo.gl/5ZwMzO

slide-38
SLIDE 38

REST APIs

  • Designate uses Flask for the v1 API, and Pecan for the v2

API.

  • designate-api is intentionally a separate service in

designate, we’ve always had a DNS based “API” in mind.

  • API v1 is in “maintenance mode” - We’re trying really hard

to not add new features here!

  • API v2 is still experimental - We have some more changes

to simplify in the pipeline!

slide-39
SLIDE 39

Central Service

  • Designate’s “Core” service - If you’re not sure, it probably belongs in here

somewhere

  • Designate’s other services are all intended to be lightweight, each doing as

little as possible - i.e. only what’s specific to the particular interface.
