Adds platform/cloudflared: a locally-managed tunnel whose ingress rules live in git. LAN/VPN-only hosts (plex, plex-vip, jackett, pihole, pihole-dns, semaphore, qbittorrent, radarr, sonarr, headlamp, unifi, crafty-mc) map to 404. The apex and *.home go to cilium-gateway-shared.gateway over TLS with matchSNItoHost. Last comes a catch-all 404. Nothing routes to the Kubernetes API. - 2-replica Deployment, hard node spread, non-root, pinned digest, PDB - default-deny plus an egress CNP: Cloudflare edge 7844/443, the Gateway, and Gateway backends by gateway-access=shared minus the LAN-only namespaces (needed because of the CVE-2025-30162 L7LB egress re-check) - PodMonitor plus two alerts that fire on absent series, with promtool tests - its own Flux Kustomization (dependsOn platform-config, wait:false, nothing depends on it), plus SOPS decryption patches in both overlays - placeholder credentials (SOPS-encrypted) so it can merge before enrolment - L0 cloudflared-ingress-rules, and a cloudflared_ scrape owner - runbooks/cloudflare-tunnel.md and decisions/2026-11-08-cloudflare-tunnel.md Co-Authored-By: Claude Opus 5.5 <[email protected]>
platform/cloudflared
Cloudflare Tunnel connector: inbound HTTPS from the Cloudflare edge to the shared Gateway, outbound-only from the cluster (no router port forward, no hairpin, no split-DNS dependency).
- Flux tier:
clusters/base/cloudflared.yaml— its own Kustomization,dependsOn: [platform-config],wait: false, and nothing depends on it. A missing or invalid credential can affect only the tunnel. - Runbook (enrolment, canary, alerts, rollback):
runbooks/cloudflare-tunnel.md - Design record:

| File | What it is |
|---|---|
config.yaml |
The locally-managed tunnel: literal tunnel UUID + ingress rules. LAN/VPN-only hosts → 404, apex + wildcard → https://cilium-gateway-shared.gateway.svc.cluster.local:443 with matchSNItoHost, catch-all 404. Never the Kubernetes API. |
cloudflared-credentials.sops.yaml |
SOPS-encrypted tunnel credentials JSON. Ships with REPLACE-ME; the operator fills it. |
deployment.yaml |
2 replicas, hard spread across nodes, non-root, read-only root fs, pinned digest; PDB minAvailable: 1. |
networkpolicy.yaml |
default-deny (single owner — not an app namespace) + Prometheus scrape allow + egress CNP: world 7844 tcp/udp and 443, the Gateway (ingress entity), and Gateway backends by gateway-access=shared minus the LAN-only namespaces. |
podmonitor.yaml, alerts.yaml |
Scrape of :2000 and the two alerts, both written to fire (not go quiet) when their series vanish. |
Phase 1 only. This component changes no live traffic: Cloudflare sends a hostname through the
tunnel only when its DNS record is a CNAME to <UUID>.cfargotunnel.com, and nothing here creates
one. Moving DNS (external-dns, Gateway annotations, Pi-hole/CoreDNS split horizon) is a later change.
