unkinben 4d1041925c Use externalTrafficPolicy: Local on the DNS services
ci/woodpecker/pr/pre-commit Pipeline was successful
ci/woodpecker/pr/kubeconform Pipeline failed
Preserves client source IPs so the authoritative/resolver source-IP ACLs
actually apply to external clients (Cluster SNATs them to node IPs).

- externalTrafficPolicy: Local on bind-authoritative/resolvers/externaldns
- bump operator to v0.1.5 (CRD link + image) for the new service field

unkinben 3ab8bcc34b Restrict authoritative queries to internal networks (#227)
Mirrors the puppet authoritative `master-zones` view (match-clients `acl-main.unkin.net`, recursion no) — restricting who can query bind-authoritative.

## Changes
- add `auth-acl-main` BindACL with the puppet authoritative acl-main.unkin.net networks (13-17,19,20,24-29)
- `allow-query { auth-acl-main; 10.42.0.0/16; }` on bind-authoritative via extraOptions

## Notes
- Implemented as a global `allow-query` rather than a BindView: dynamic *primary* zones inside a view would need per-view `allow-new-zones` (an operator gap). Functionally equivalent for the single master-zones view.
- `10.42.0.0/16` (pod network) is included so secondaries can SOA-refresh from the primary during catalog replication — without it, replication breaks.
- Works on the current operator (no HOLD).

## Caveat
The DNS Services use externalTrafficPolicy: Cluster, which SNATs external clients to node IPs (198.18.19.x, already in acl-main), so this ACL doesn't truly restrict *external* clients yet. True source-IP restriction needs externalTrafficPolicy: Local — happy to switch if wanted.

unkinben c8d61205ce Configure resolvers like puppet (openforwarder view + forward zones) (#226)
## Why
`dig google.com @198.18.200.7` was refused: the resolver never set allow-recursion, so BIND defaulted to localnets/localhost. This mirrors the puppet resolver (/etc/named/views.conf + acls.conf) exactly.

## Changes
- `openforwarder` BindView: `match-clients` = the 4 internal ACLs, recursion yes, allow-recursion/allow-query `any` (match-clients gates)
- 4 BindACLs from puppet acls.conf (acl-main.unkin.net/acl-dmz/acl-common/acl-nomad-jobs)
- 26 conditional forward zones in the view (unkin→198.18.19.15, consul→.14, k8s→.20, dmz/network/prod + 10.10.x reverse → 10.10.16.32/33)
- global forwarders 8.8.8.8/1.1.1.1
- operator image → v0.1.4

## Note
Forward-zone upstreams point at the **puppet anycast** servers (still authoritative during migration); flip to the in-cluster authoritative/externaldns LBs once zone data is migrated.

## Validated
kustomize build (59 docs), kubeconform clean.

unkinben ce8ebc71ce Consolidate BIND DNS into one bind-internal namespace (#225)
**HOLD until v0.1.3 is tagged/built** (operator #4 merged + tagged) — this PR bumps the operator to v0.1.3, whose CRD adds the `clusterRef` field these keys use.

## Why
Put all BIND DNS services in one `bind-internal` namespace and name the StatefulSets clearly.

## Changes
- 3 clusters consolidated into `bind-internal`, StatefulSets renamed **bind-authoritative** / **bind-resolvers** / **bind-externaldns**; LBs kept on 198.18.200.6/.7/.8; external-dns hostnames renamed to match
- `clusterRef` added to `transfer-key` (→ bind-authoritative) and `externaldns-key` (→ bind-externaldns) so keys are scoped per cluster
- removed the old `ns-auth`/`ns-resolver`/`ns-externaldns` apps; ApplicationSet + AppProject now list `bind-internal`
- bumped `bind-system` operator to **v0.1.3** (CRD link + image)
- operator stays in `bind-system`

## Deploy impact
ArgoCD prunes the old ns-* namespaces (StatefulSets/PVCs — data is only seed SOA+NS, no migrated records yet) and creates the renamed clusters in bind-internal.

## Validated
`kustomize build` → 28 docs (3 BindCluster, 20 BindZone, 2 catalog, 2 keys, ns); kubeconform clean.
