fix(externaldns): remove experimental Gateway API route sources

TLSRoute, GRPCRoute, TCPRoute, UDPRoute CRDs are not installed (Traefik experimentalChannel: false), causing external-dns to crash with a context deadline timeout on every sync cycle. Keep only gateway-httproute which is the only route type in use.

unkinben	0940cc20f8	fix(traefik): listen on port 443 directly for Gateway API compatibility (#138 ) ## Problem Gateway listeners with `port: 443` were rejected with `PortUnavailable: Cannot find entryPoint for Gateway: no matching entryPoint for port 443 and protocol "HTTPS"`. Traefik matches Gateway listener ports against its internal entryPoint ports (pod-level), not the Service's `exposedPort`. The `websecure` entryPoint was configured on port `8443`, so port `443` listeners had no match. ## Fix - `ports.websecure.port: 443` — Traefik now binds directly on 443 - `securityContext.capabilities.add: [NET_BIND_SERVICE]` — allows a non-root process to bind to privileged ports (<1024) The Service `exposedPort` stays at `443`, so external connectivity is unchanged. All existing Gateway listeners (`port: 443`) are correct as-is. Applies to both internal and external Traefik instances. ## Test plan - [ ] Traefik pods restart cleanly - [ ] `kubectl get gateway -A` shows listeners as `Programmed: True` - [ ] `https://rancher.k8s.syd1.au.unkin.net` (already merged) is reachable Reviewed-on: #138	2026-05-23 00:44:13 +10:00

unkinben	64dc5a0242	fix(traefik): add instance labels to GatewayClasses (#137 ) ## Problem GatewayClasses were `Unknown` even after controllerName was fixed. The `kubernetesGateway` `labelSelector` applies to all watched resources, including GatewayClasses themselves. Since neither GatewayClass had a `traefik.io/instance` label, both Traefik instances filtered them out and never accepted them. ## Fix - `gatewayclass-internal.yaml`: add `traefik.io/instance: internal` - `gatewayclass-external.yaml`: add `traefik.io/instance: external` ## Test plan - [ ] `kubectl get gatewayclass` shows both as `Accepted: True` Reviewed-on: #137	2026-05-23 00:23:18 +10:00
unkinben	57c14d32c0	fix(traefik): remove invalid controllerName flag causing CrashLoopBackOff (#136 ) ## URGENT — Traefik pods are CrashLoopBackOff The merged PR #135 added `--providers.kubernetesgateway.controllerName` as an `additionalArguments` entry. Traefik v3.7.0 does not support this flag and fails immediately on startup. Old replica sets are still running (one pod each) but new pods cannot come up. ## Fix - Remove `additionalArguments` from both `values-internal.yaml` and `values-external.yaml` - Revert GatewayClass `controllerName` back to `traefik.io/gateway-controller` (the hardcoded Traefik default — no override mechanism exists in v3.7.0) ## After merge GatewayClasses will remain `Unknown` until a separate solution for internal/external separation is implemented (the `labelSelector` approach needs further investigation).

unkinben	2df359c4a9	fix(traefik): set controllerName on GatewayClasses and Traefik providers (#135 ) ## Problem Both GatewayClasses (`traefik-internal`, `traefik-external`) were stuck as `Unknown`. Neither Traefik deployment had `controllerName` set in `kubernetesGateway`, so both defaulted to `traefik.io/gateway-controller` — which matched neither GatewayClass. ## Fix - `gatewayclass-internal.yaml`: `controllerName: traefik.io/gateway-controller-internal` - `gatewayclass-external.yaml`: `controllerName: traefik.io/gateway-controller-external` - `values-internal.yaml`: added `controllerName: traefik.io/gateway-controller-internal` - `values-external.yaml`: added `controllerName: traefik.io/gateway-controller-external` ## Test plan - [ ] ArgoCD syncs traefik-system cleanly - [ ] `kubectl get gatewayclass` shows both as `Accepted: True` Reviewed-on: #135	2026-05-22 23:44:06 +10:00
