Runbook 07 — Designate Zones and Records (v1: A records only)

STATUS: PLACEHOLDER — drafted post-deploy.

Purpose

Create the cloud's DNS zones in Designate, populate API VIP A records (v1: IPv4 only), and configure Neutron defaults to push Designate as tenant DNS resolver.

Prerequisites

• Designate charm in active/idle
• Keystone, Neutron API reachable
• API VIP hostnames already in /etc/hosts on all OpenStack nodes (per D-008 Layer 0 bootstrap)

TODO

• Create primary zone:

  `openstack zone create --email admin@neumatrix.local \
   omega.dc0.vr0.cloud.neumatrix.local.`

• Populate API VIP A records for each public service:

  - keystone, glance, nova, neutron, cinder, placement, octavia,
    barbican, magnum, horizon, designate
  - **v1: A records only** (IPv4 VIPs from the Provider API VIP range
    10.12.4.224-.254)
  - **v2 will add AAAA records when IPv6 Provider VIPs become active**

• Configure Neutron defaults:

  `juju config neutron-api default-dns-domain=omega.dc0.vr0.cloud.neumatrix.local.`
  `juju config neutron-api dns-domain=omega.dc0.vr0.cloud.neumatrix.local.`

• Configure Neutron DHCP to push Designate as resolver:

  `juju config neutron-api dns-servers=<designate-vip-ipv4>`

• Verify from a test tenant VM:

  `nslookup keystone.omega.dc0.vr0.cloud.neumatrix.local`
  resolves to Provider API VIP
