## Why
v0.2.2's config-hash rolling restart exposed a latent non-determinism: `client.List` returns cache-ordered results, so the resolver's forward zones reshuffled every reconcile, flipping the config hash and rolling `bind-resolvers-2` endlessly. v0.2.3 (bind-operator #11) sorts every rendered list so `named.conf` is byte-identical across reconciles and the hash is stable.
## Changes
- Bump the operator image (`bind-system/deployment.yaml`) and the pulled CRD bundle URL (`bind-system/kustomization.yaml`) to `v0.2.3`.
- Bump the `bind-tsig-api` image (`bind-internal/tsig-api/tsig-api.yaml`) to `v0.2.3`.
CRDs are unchanged from v0.2.2 (controller-only change), so the generated kubeconform schemas need no update.
## Validation
- `bind-system` renders with the v0.2.3 CRD bundle; `bind-internal` passes `kubeconform` (56/56); pre-commit clean.
## Deploy note
On deploy the deterministic operator stops churning the ConfigMap; the config hash stabilizes and the stuck resolver rolling update completes, leaving all three pods Ready on one revision.

## Why
ArgoCD had no external ingress and only local admin auth. This exposes `argocd-server` behind the traefik-internal gateway and enables Authentik SSO, so operators log in with their Authentik identity and group membership. Pairs with unkin/terraform-authentik#3 (creates the OAuth2 provider).
## Changes
- **argocd-cm**: set `url` and `oidc.config` (Authentik issuer `identity.unkin.net/application/o/argocd/`, `argocd` client, openid/profile/email scopes). Client secret resolved from the `argocd-oidc` Secret via `$argocd-oidc:client_secret`.
- **argocd-rbac-cm**: match RBAC on the `groups` claim; default `role:readonly`; map the `argocd-admins` Authentik group to `role:admin`.
- **argocd-cmd-params-cm**: `server.insecure=true` so `argocd-server` serves HTTP behind the TLS-terminating gateway.
- Add **Gateway + HTTPRoutes** for `argocd.k8s.syd1.au.unkin.net` (mirrors the grafana pattern: traefik-internal, vault-issuer cert, external-dns).
- Add **VaultAuth + VaultStaticSecret** sourcing the OIDC client secret from `kv/kubernetes/namespace/argocd/default/oauth-credentials` into the `argocd-oidc` Secret (labelled `part-of=argocd` so ArgoCD will resolve the `$` reference).
## Notes / rollout
- Seed the client secret in Vault out of band (same path terraform-authentik reads).
- The argocd namespace `default` SA already has Vault read access via the `default` k8s role, so no terraform-vault change is needed.
- `argocd-server` needs a one-time rollout restart to pick up `server.insecure`.
Validated with `kustomize build --enable-helm clusters/au-syd1/bootstrap`, `make kubeconform`, and pre-commit (yamllint + no-plain-secrets).

## Why
v0.2.2 (bind-operator #10) stamps a `bind.unkin.net/config-hash` on the pod template, so a ConfigMap or `keys.conf` change flips the hash and triggers an operator-driven rolling restart. This fixes the class of bug where config edits (ACLs, forwarders, `validate-except`, primary address, TSIG rotation) never reached running pods — they held a startup snapshot and needed manual pod deletes.
## Changes
- Bump the operator image (`bind-system/deployment.yaml`) and the pulled CRD bundle URL (`bind-system/kustomization.yaml`) to `v0.2.2`.
- Bump the `bind-tsig-api` image (`bind-internal/tsig-api/tsig-api.yaml`) to `v0.2.2`.
CRDs are unchanged from v0.2.1 (controller-only change), so the generated kubeconform schemas need no update.
## Validation
- `bind-system` renders with the v0.2.2 CRD bundle; pre-commit clean.
## Deploy note
When the v0.2.2 operator first reconciles it stamps the config-hash annotation, triggering **one rolling restart per bind StatefulSet** — expected, and it also pulls in any already-pending config. From then on, config changes roll pods automatically.

## 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.

## 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`.
