- Remove viktorbarzin.me from split DNS (same IPs as public DNS,
was adding unnecessary tunnel overhead for every DNS query)
- Narrow reverse DNS split scope from 10.0.0.0/8 → 10.0.20.0/24
and 10.0.10.0/24 only; 192.168.0.0/16 → 192.168.1.0/24 only
- Add extra_records for key internal services (technitium, k8s-master)
for instant MagicDNS resolution without tunnel roundtrip
- Replace full Tailscale DERP map (29 regions) with curated set:
home + 8 European + 5 global fallback DERPs (14 total)
- Add custom derp.yaml to ConfigMap, sourced from Vault
Port 80 DERP dropped — Traefik's global HTTP→HTTPS redirect
prevents non-TLS DERP upgrades on the web entrypoint.
- Add SQLite backup CronJob (every 6h to NFS for cloud sync pickup)
- Move headscale-ui secrets (COOKIE_SECRET, ROOT_API_KEY) from hardcoded
values to Vault-managed secrets
- Add DERP IPv6 address (2001:470:6e:43d::2) for IPv6-capable clients
- Clean up stale test nodes, duplicate users, rename "localhost" nodes
Also updated headscale_config in Vault to include DERP ipv6 field
and headscale_ui_cookie_secret/headscale_ui_api_key secrets.
Phase 3: all 27 platform modules now run as independent stacks.
Platform reduced to empty shell (outputs only) for backward compat
with 72 app stacks that declare dependency "platform".
Fixed technitium cross-module dashboard reference by copying file.
Woodpecker pipeline applies all 27+1 stacks in parallel via loop.
All applied with zero destroys.
