unkinben da4a66046a Add Tier-2 per-app Vector transform pipelines (structured logs) (#320)
Why: extend the Tier-1 survey with 7 more high-value log sources so they parse into logs.raw columns/.fields for real querying instead of the generic catch-all. **Stacks on #318 — merge after it.**

How:
- 7 mutually-exclusive app_route conditions + parse transforms into the ClickHouse sink: **bind_query** (k8s bind-* + VM named), **rancher_audit** (cattle-system sidecar JSON), **cnpg_pg** (ONE transform for all 10 CNPG clusters via the `.postgres` container), **gitea** (router+access, k8s+VM), **puppet** (openvoxserver/openvoxdb logback + access), **litellm** (JSON request logs), **postfix** (per-line maillog).
- Carve `.postgres` out of the Tier-1 authentik route + new puppet/gitea/litellm routes so the single cnpg_pg route claims every CNPG pod without double-insert (keeps app_route mutually exclusive). Catch-all intact.
- Companion k8s flips in this PR: litellm `JSON_LOGS=True`; bind `querylog yes` on both bind-internal BindClusters; gitea router+access logging to stdout. Rancher auditLog was already on.
- 15 new `vector test` cases (routing + field extraction + authentik-postgres→cnpg exclusivity proof); all 35 green (vector 0.57). Fields go into the existing `fields Map(String,String)` — no DDL change.

Puppet-side follow-ups (out of scope for argocd): enable named query logging (profiles/dns/server.pp); ship the VM vector rollout with `.file`/`.SYSLOG_IDENTIFIER` tags for named/gitea/puppetserver(+multiline logback join)/postfix maillog.

unkinben 7a889ca326 Flip resolver forwarding for k8s zones to the in-cluster bind (#288)
## Why

Step 3 of 3 in the external-dns → in-cluster bind migration: the client-visible cutover. The `openforwarder` resolvers currently forward `k8s.syd1.au.unkin.net` to the legacy VM anycast `198.18.19.20` (a temporary measure — commit 7ee5dfb) and have NO forwarder at all for the reverse zone `200.18.198.in-addr.arpa`. Once external-dns publishes to the in-cluster `bind-externaldns` (PR 2), resolvers must read from it.

## Changes

- Repoints the `fwd-k8s-syd1-au-unkin-net` forwarder from `198.18.19.20` (legacy VM) to `198.18.200.8` (in-cluster `bind-externaldns` VIP).
- Adds `fwd-200-18-198-in-addr-arpa` forwarding `200.18.198.in-addr.arpa` → `198.18.200.8`, closing the reverse-zone gap so PTR lookups for the k8s LB range keep resolving after cutover. Modeled exactly on the existing forward-zone entries.
- Refreshes the header comment to describe the in-cluster upstream.

`kubectl kustomize apps/overlays/au-syd1/bind-internal` builds clean; both zones render with forwarder `198.18.200.8` and there is no residual `198.18.19.20`.

## Merge gate

- PR 2 (`benvin/externaldns-incluster`) merged, AND
- record parity confirmed between legacy and in-cluster for the forward zone. Spot-check (repeat for each name):
  ```
  for n in puppetca puppet puppetdb encapi pdbmux artifactapi consul; do
    echo "$n:"
    dig +short @198.18.19.20 A $n.k8s.syd1.au.unkin.net
    dig +short @198.18.200.8  A $n.k8s.syd1.au.unkin.net
  done
  # plus 2-3 PTRs in the reverse zone:
  dig +short @198.18.19.20 -x 198.18.200.8
  dig +short @198.18.200.8  -x 198.18.200.8
  ```
  A/PTR answers from `198.18.200.8` must match those from `198.18.19.20` before merging.

## Verification (after merge)

```
dig +short @198.18.200.7 A puppet.k8s.syd1.au.unkin.net   # resolvers VIP
dig +short @198.18.200.7 -x 198.18.200.8                  # reverse via resolvers
```
Resolution through the `bind-resolvers` VIP should now answer for both the forward and reverse k8s zones.

## Rollback

Revert this PR — the `fwd-k8s-syd1-au-unkin-net` forwarder returns to `198.18.19.20` and the reverse forward is removed. The legacy VM is untouched and remains authoritative until decommission.

unkinben 39b180aec9 bind-internal: allow k8s pod network to query the resolvers (#271)
Kubernetes nodes querying the bind-resolvers LoadBalancer VIP (198.18.200.7) get REFUSED (EDE 18 Prohibited).

The service is `externalTrafficPolicy: Local`, which preserves the client source IP for traffic entering the cluster from outside — but a node querying the VIP never leaves via OSPF. Its own kube-proxy DNATs the LB IP in the OUTPUT chain and masquerades the source to a cluster-internal address (the node's flannel.1, e.g. 10.42.x.x). That address is not in `acl-main.unkin.net`, so the openforwarder view's match-clients rejects the query.

External clients preserve their real source IP and match acl-main, which is why only in-cluster hosts were affected.

Add `10.42.0.0/16` to `acl-main.unkin.net` so node-originated (masqueraded) resolver queries are permitted. This mirrors the authoritative cluster, which already allows the pod network (`allow-query { ...; 10.42.0.0/16; }`).

unkinben 7ee5dfbbcd TEMP: forward k8s.syd1.au.unkin.net to external external-dns service (#269)
The bind-resolvers `openforwarder` view forwarded `k8s.syd1.au.unkin.net` to the in-cluster bind-externaldns (198.18.200.8), which is not reliably serving those records yet, so lookups return NXDOMAIN.

Concrete impact: Gitea cannot resolve the k8s-hosted CI host, so its outbound webhook fails and tagged releases never trigger CI (e.g. cutting a new bind-operator release from a tag).

This points the `fwd-k8s-syd1-au-unkin-net` forwarder at the existing external external-dns bind service anycast **198.18.19.20** (puppet `roles::infra::dns::externaldns` — master `ausyd1nxvm2127` + slaves `2128`/`2129`, advertised via OSPF), which still holds the working `k8s.syd1.au.unkin.net` records. It is in the same 198.18.19.0/24 anycast family as the consul forwarder (198.18.19.14) the resolvers already use, so it is reachable from the pods.

Temporary measure. Revert to 198.18.200.8 once external-dns publishes to the in-cluster bind-externaldns service. Only the forward target changes; no CRD/schema changes.

unkinben 197991a6ca bind-internal: allow admin workstation to query the resolver (#259)
## Why
Follow-up to #258 (which added workstation+router to the *authoritative* ACL). The **resolver** (bind-resolvers, 198.18.200.7) has its own `acl-main.unkin.net` gating its `openforwarder` view; the workstation is not in it, so recursive queries return REFUSED. This lets the workstation use the resolver as its normal nameserver.

## Changes
- Add `10.10.12.200/32` (workstation, wireguard) to resolver `acl-main.unkin.net`
- Add `198.18.21.160/32` (router) explicitly for documentation; already covered by existing `198.18.21.160/27` and `198.18.21.0/24` (no functional change for the router)

unkinben 69788a967c Fix validate-except syntax (resolver crash-loop) (#252)
## Why — urgent

PR #251 added `validate-except` to the resolver `BindCluster` but the list omitted the trailing semicolon after the final entry. `named` requires **every** entry in a list to be semicolon-terminated, including the last before the closing brace, so it fails config parse and the resolver pods crash-loop:

```
/run/named/named.conf:18: missing ';' before '}'
loading configuration: failure
exiting (due to fatal error)
```

The resolvers (`.7`) are down until this lands; the authoritative (`.6`/`.9`) and externaldns (`.8`) are unaffected.

## Fix

```diff
- validate-except { unkin.net; 18.198.in-addr.arpa; consul }
+ validate-except { unkin.net; 18.198.in-addr.arpa; consul; }
```

Renders to `validate-except { unkin.net; 18.198.in-addr.arpa; consul; };` — valid.

## Recovery

On merge + ArgoCD sync, the operator re-renders the ConfigMap with valid config and the crash-looping pods self-heal on their next restart (no manual `rollout restart` needed). Validated: `bind-internal` renders and pre-commit clean.

unkinben 5e7dc580b7 Exempt internal split-horizon zones from resolver DNSSEC validation (#251)
## Why

Resolving any `unkin.net` record through the resolver (`.7`) returns **SERVFAIL**, while the authoritative (`.6`) answers fine. Confirmed from the resolver's querylog:

```
view openforwarder:   validating unkin.net/SOA: got insecure response; parent indicates it should be secure
broken trust chain resolving 'ausyd1nxvm2120.main.unkin.net/A/IN': 198.18.200.6#53
query failed (broken trust chain)
```

The resolver runs `dnssec-validation auto`. The public `unkin.net` is DNSSEC-signed (the `.net` parent publishes a DS), but the in-cluster split-horizon authoritative serves `unkin.net` **unsigned**. The validator sees "parent says secure" + an insecure answer → treats it as spoofing → SERVFAIL. The authoritative works directly because it does no validation.

## Fix

Add `validate-except` (via `spec.extraOptions`) for the forwarded internal domains, so the resolver treats them as insecure and skips validation:

```
validate-except { unkin.net; 18.198.in-addr.arpa; consul }
```

- `unkin.net` covers all `*.unkin.net` (incl. `main.unkin.net`, `k8s.syd1.au.unkin.net`)
- `18.198.in-addr.arpa` covers every `NN.18.198.in-addr.arpa` reverse zone (subtree)
- `consul` covers the consul TLD

This also makes internal resolution independent of Internet egress (no DNSSEC chain-walk needed). External-name validation is unchanged. No operator change required.

## Validation

`bind-internal` renders and passes `kubeconform` (56/56); pre-commit clean.

## Activation

After merge + operator reconcile, the resolver ConfigMap re-renders; the running pods hold a startup snapshot, so they need a reload: `kubectl -n bind-internal rollout restart statefulset/bind-resolvers`.

unkinben e030f07986 Add primary (write) Services to authoritative + externaldns (#229)
**Stacked on #228** (needs operator v0.1.5). Merge #228 first; the diff collapses to just this after.

## Why
Writes (RFC2136/nsupdate) must go to pod-0 — the round-robin read Service would land them on a secondary (rejected). Adds a dedicated write endpoint per cluster (operator v0.1.5 `primaryService`).

## Changes
- `bind-authoritative`: LoadBalancer write endpoint on **198.18.200.9** (`bind-authoritative-primary`)
- `bind-externaldns`: ClusterIP write endpoint (`bind-externaldns-primary`, for in-cluster writers)
- regenerate the bindcluster kubeconform schema (primaryService + externalTrafficPolicy)

## Deferred
external-dns is **not** repointed at `bind-externaldns-primary` yet: it authenticates with the existing TSIG key, which the operator-generated key won't match until the planned Vault-sync + secret-reflection features exist. Until then external-dns keeps writing to the puppet externaldns.

## Validated
kustomize build + kubeconform (3 BindClusters valid against the v0.1.5 schema).

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.
