[ci skip] Infrastructure hardening: security, monitoring, reliability, maintainability
Phase 1 - Critical Security:
- Netbox: move hardcoded DB/superuser passwords to variables
- MeshCentral: disable public registration, add Authentik auth
- Traefik: disable insecure API dashboard (api.insecure=false)
- Traefik: configure forwarded headers with Cloudflare trusted IPs
Phase 2 - Security Hardening:
- Add security headers middleware (HSTS, X-Frame-Options, nosniff, etc.)
- Add Kyverno pod security policies in audit mode (privileged, host
namespaces, SYS_ADMIN, trusted registries)
- Tighten rate limiting (avg=10, burst=50)
- Add Authentik protection to grampsweb
Phase 3 - Monitoring & Alerting:
- Add critical service alerts (PostgreSQL, MySQL, Redis, Headscale,
Authentik, Loki)
- Increase Loki retention from 7 to 30 days (720h)
- Add predictive PV filling alert (predict_linear)
- Re-enable Hackmd and Privatebin down alerts
Phase 4 - Reliability:
- Add resource requests/limits to Redis, DBaaS, Technitium, Headscale,
Vaultwarden, Uptime Kuma
- Increase Alloy DaemonSet memory to 512Mi/1Gi
Phase 6 - Maintainability:
- Extract duplicated tiers locals to terragrunt.hcl generate block
(removed from 67 stacks)
- Replace hardcoded NFS IP 10.0.10.15 with var.nfs_server (114
instances across 63 files)
- Replace hardcoded Redis/PostgreSQL/MySQL/Ollama/mail host references
with variables across ~35 stacks
- Migrate xray raw ingress resources to ingress_factory modules

[ci skip] right-size all pod resources based on VPA + live metrics audit
Full cluster resource audit: cross-referenced Goldilocks VPA recommendations,
live kubectl top metrics, and Terraform definitions for 100+ containers.
Critical fixes:
- dashy: CPU throttled at 98% (490m/500m) → 2 CPU limit
- stirling-pdf: CPU throttled at 99.7% (299m/300m) → 2 CPU limit
- traefik auth-proxy/bot-block-proxy: mem limit 32Mi → 128Mi
Added explicit resources to ~40 containers that had none:
- audiobookshelf, changedetection, cyberchef, dawarich, diun, echo,
excalidraw, freshrss, hackmd, isponsorblocktv, linkwarden, n8n,
navidrome, ntfy, owntracks, privatebin, send, shadowsocks, tandoor,
tor-proxy, wealthfolio, networking-toolbox, rybbit, mailserver,
cloudflared, pgadmin, phpmyadmin, crowdsec-web, xray, wireguard,
k8s-portal, tuya-bridge, ollama-ui, whisper, piper, immich-server,
immich-postgresql, osrm-foot
GPU containers: added CPU/mem alongside GPU limits:
- ollama: removed CPU/mem limits (models vary in size), keep GPU only
- frigate: req 500m/2Gi, lim 4/8Gi + GPU
- immich-ml: req 100m/1Gi, lim 2/4Gi + GPU
Right-sized ~25 over-provisioned containers:
- kms-web-page: 500m/512Mi → 50m/64Mi (was using 0m/10Mi)
- onlyoffice: CPU 8 → 2 (VPA upper 45m)
- realestate-crawler-api: CPU 2000m → 250m
- blog/travel-blog/webhook-handler: 500m → 100m
- coturn/health/plotting-book: reduced to match actual usage
Conservative methodology: limits = max(VPA upper * 2, live usage * 2)

right-size 14 services and scale down GPU-heavy workloads [ci skip]
Memory right-sizing based on VPA upperBound analysis:

dawarich 512→768Mi, kyverno-cleanup 128→192Mi, linkwarden 768→1Gi,
navidrome 64→128Mi, listenarr 768→896Mi, privatebin 64→128Mi,
ntfy 64→128Mi, health 128→256Mi, dbaas quota 16→20Gi,
mysql-operator 384→512Mi
- Decreases: rybbit 768→384Mi, nvidia-exporter added explicit 192Mi,
dcgm-exporter 2560→1536Mi
- Scale to 0: ebook2audiobook/audiblez-web, whisper (GPU node pressure)
Net effect: -496Mi cluster-wide, 13 ContainerNearOOM alerts resolved,
all ResourceQuota pressures cleared, GPU health green.
