Changelog 2026-07-15 -- D-120 ADOPTED: Office1 service re-IP into the static band

What changed

Adopted D-120 (static-services addressing convention for MAAS-managed compose /24s) as option (a), executed, and re-IP'd Office1's two running services out of the MAAS node band into the .2-.49 static band:

office1-netbox     10.10.1.201 -> 10.10.1.10
office1-tailscale  10.10.1.202 -> 10.10.1.11

No wipe. Both services verified on the wire:

  • NetBox: HTTP 200 at http://10.10.1.10:8000/login/, reachable vcloud-side; old .201 dead.
  • Tailscale: BackendState=Running, PrimaryRoutes=["10.10.0.0/22"] unchanged, tailnet 100.64.0.53 unchanged; old .202 dead.

How (method, for the DC replication that reuses this)

  • MAAS could NOT be updated -- it refuses interface edits on a Deployed machine ("Cannot unlink subnet interface because the machine is not New, Ready, Allocated, or Broken"). The only lift is Release->redeploy = WIPE (forbidden; destroys the seeded sandbox). So MAAS-model drift is ACCEPTED: MAAS still shows .201/.202 mode=auto. It reconciles for free at the next teardown/redeploy. No collision: MAAS auto-assigns nodes from .201+ upward (observed -- the two services themselves landed at .201/.202), so the low .2-.49 band is off its allocation path. (Being outside the dynamic range is NOT the guarantee; the whole non-dynamic space is the static pool.)
  • The live address was set on each guest via BOTH /etc/netplan/50-cloud-init.yaml and /etc/cloud/cloud.cfg.d/50-curtin-networking.cfg (the latter so it survives a reboot / cloud-init re-render), then netplan apply. Backups saved on each guest: .bak-reip201 / .bak-reip202.
  • Driven over lxc exec from voffice1, NOT SSH-to-the-guest-IP -- the LXD socket is immune to the netplan apply that swaps the address, so the control channel never dropped. lxc exec/ console was also confirmed as the recovery backstop BEFORE the first apply.
  • NetBox ALLOWED_HOSTS is * (config default, not overridden in env/netbox.env), so it served at .10 with no restart. Tailscale re-asserted automatically (no tailscale up needed).

Repo references swept (.201->.10, .202->.11)

  • Code: SANDBOX_HOSTS allowlist in netbox/dc-dc-prefixes-import.py, netbox/roles-aggregates-import.py, netbox/d115-office-carve.py; tests/dc-dc-prefixes-import/test_logic.py (both sandbox-URL hosts). The on-box working copy /home/ubuntu/nbimport/netbox/d115-office-carve.py was updated too (else a --commit against the now-.10 sandbox would be REFUSED as non-sandbox).
  • Docs: docs/vr1-office1-as-built.md (+ a MAAS-model-drift caveat), docs/session-ledger.md, docs/dc-dc-netbox-buildout-scope.md, docs/dc-dc-deployment-workflow.md, runbooks/dc-dc-phase1-office1-standup.md, docs/design-decisions.md (D-120 flip + Execution), runbooks/dc-dc-office1-service-reip.md (PENDING markers resolved to the measured method).
  • Dated changelogs left as historical snapshots (they record the deploy-time .201/.202).

Gauntlet

bash scripts/run-tests-all.sh -> ALL GREEN (58 harnesses). bash scripts/repo-lint.sh -> 0 fail, 1 documented legacy WARN (design-decisions non-ASCII carve-out; my additions are ASCII-clean).

Still owed (NOT done here)

  • D-120 Step 6 / C2: register the 10.10.1.0/24 child ranges (static .2-.49 / dynamic .100-.200 / node .201-.254) and the two service IPs IN the sandbox NetBox, then feed upstream. Rides with C2.

Revert

  • Repo: git revert <this commit> restores the .201/.202 references.
  • Live services: on each guest via lxc exec, restore /etc/netplan/50-cloud-init.yaml and /etc/cloud/cloud.cfg.d/50-curtin-networking.cfg from the .bak-reip201 / .bak-reip202 backups, then netplan apply. MAAS needs no rollback (its model was never changed). The on-box importer copy reverts with sed -i s#10.10.1.10#10.10.1.201#g /home/ubuntu/nbimport/netbox/d115-office-carve.py.
