[ci skip] Redis: upgrade to Bitnami Helm chart with Sentinel HA
- Replace manual redis:7-alpine deployment with Bitnami Redis Helm chart v25.3.2
- Architecture: replication with Sentinel (1 master + 1 replica + sentinels)
- Automatic failover via Sentinel (quorum=2, masterSet=mymaster)
- Service 'redis.redis' always points at current master (transparent to clients)
- 120 clients connected immediately after deployment
- Sentinel confirmed tracking redis-node-0 as master
- Local-path PVCs for persistence (2Gi per node)
- Auth disabled (matches previous setup)
- Hourly RDB backup CronJob to NFS preserved
- OCI chart pulled via pull-through cache (10.0.20.10:5000)

[ci skip] Phase 2: migrate Redis from NFS to local disk
- Switch from redis/redis-stack:latest to redis:7-alpine
  (modules were completely unused — zero module commands in stats)
- Move data from NFS (/mnt/main/redis) to local-path PVC
  (RDB saves: 39s on NFS → <1s on local disk)
- Start fresh (old RDB had redis-stack module data incompatible with plain redis;
  all Redis data is transient — queues and caches rebuild automatically)
- Add hourly redis-backup CronJob: redis-cli --rdb to NFS for backup pipeline
- Remove RedisInsight UI ingress (port 8001, only in redis-stack)
- Add redis-backup to NFS exports
- 110 clients reconnected immediately after switchover
- Memory savings: ~100MB from dropping unused modules

[ci skip] codify CNPG PostgreSQL in Terraform, decommission old NFS-backed PG
Phase 1 complete — PostgreSQL fully migrated off NFS:

dbaas module changes:
- Replace old kubernetes_deployment.postgres with null_resource.pg_cluster
  (CNPG Cluster CR managed via kubectl apply due to webhook mutation issues)
- Update postgresql Service selector: app=postgresql → cnpg primary
- Update backup CronJob: use postgres user + read password from CNPG secret
  (pg-cluster-superuser) instead of hardcoded root password
- Add kube_config_path variable for kubectl in null_resource
- Old deployment deleted from cluster (was scaled to 0)

CNPG cluster status:
- 2 instances: primary (k8s-node4), replica (k8s-node2)
- PostGIS image (ghcr.io/cloudnative-pg/postgis:16)
- 20Gi local-path storage per instance
- All 13 dependent services verified running
- Backup CronJob verified working with new endpoint

[ci skip] Phase 1: PostgreSQL migrated to CNPG on local disk
Major milestone - shared PostgreSQL moved from NFS to CloudNativePG:
- CNPG cluster (pg-cluster) running in dbaas namespace on local-path storage
- PostGIS image (ghcr.io/cloudnative-pg/postgis:16) for dawarich compatibility
- All 20 databases and 19 roles restored from pg_dumpall backup
- postgresql.dbaas Service patched to point at CNPG primary
- Old PG deployment scaled to 0 (NFS data intact for rollback)
- All 12+ dependent services verified running:
  authentik, n8n, dawarich, tandoor, linkwarden, netbox, woodpecker,
  rybbit, affine, health, resume, trading-bot, atuin
- Authentik PgBouncer working through the switched endpoint

TODO: codify CNPG cluster in Terraform, add 2nd replica, update backup CronJob

fix: use plain string for cache_from/cache_to and fix caretta helm_release
- cache_from/cache_to must be plain strings, not YAML lists — the
  plugin-docker-buildx treats them as single string values and the
  Woodpecker settings layer was splitting comma-separated list items
  into separate --cache-from flags (type=registry and ref=... separately)
- caretta.tf: replace deprecated set{} blocks with values=[yamlencode()]
  to fix Terraform plan error with newer Helm provider

[ci skip] nextcloud: increase resource limits to prevent OOM crash loop
Default LimitRange (256Mi) was too low — pod was using 227Mi/256Mi and
getting OOM killed under sync client load, causing 500s and blank web UI.

[ci skip] technitium: add primary-secondary DNS HA with AXFR zone replication
Secondary instance on a separate node replicates all zones from primary via

least 1 DNS pod survives voluntary disruptions. Setup job automates zone
transfer enablement and secondary zone creation via Technitium REST API.

[ci skip] VPA: reduce LimitRange defaults, add overcommit check, protect tier-0
- Reduce Kyverno LimitRange default limits ~4x across all tiers to fix
  800-900% memory overcommitment on worker nodes
- Add cluster health check #25: per-node resource overcommitment
  showing requests and limits vs allocatable capacity
- Add Kyverno policy for Goldilocks VPA mode by tier: tier-0 namespaces
  get VPA Off mode (recommend only, no evictions) to prevent downtime
  on critical infra (traefik, cloudflared, authentik, technitium, etc.)
- Non-tier-0 namespaces get VPA Auto mode for active right-sizing

[ci skip] kyverno: scale to 2 replicas, eliminate API calls from policies
- Scale admission controller to 2 replicas with topology spread across nodes
- Rewrite inject-priority-class-from-tier: use namespaceSelector instead of
  API call per pod admission (eliminates Kyverno→API server round-trip)
- Rewrite sync-tier-label-from-namespace: same namespaceSelector approach
- Extract governance_tiers local to DRY up tier definitions

[ci skip] Fix Woodpecker GitHub forge: add explicit GITHUB_URL to prevent Forgejo URL bleed
When both WOODPECKER_GITHUB and WOODPECKER_FORGEJO are enabled without
an explicit WOODPECKER_GITHUB_URL, the GitHub forge inherits the Forgejo
URL causing all GitHub API calls to hit forgejo.viktorbarzin.me with
GitHub OAuth credentials, resulting in 401 Unauthorized on repo add and
cron jobs. Also adds Forgejo forge variables to Terraform.

[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
