afb8a16623 [infra] Scale down unused services + remove DoH ingress
Scale to 0 replicas:
- ollama: low usage, saves ~2Gi memory + 59GB NFS-SSD model data idle
- poison-fountain: RSS link archiver, not actively used
- travel-blog: Hugo blog, not actively used

Remove technitium DoH ingress (dns.viktorbarzin.me): externally unreachable
and unused. DNS is served on UDP/TCP port 53 via LoadBalancer (10.0.20.201).

Clears 3 of 5 ExternalAccessDivergence services. Remaining 2 (pdf, travel)
should clear now that the Uptime Kuma monitors will report both down.

e80b2f026f [infra] Migrate Terraform state from local SOPS to PostgreSQL backend
Two-tier state architecture:
- Tier 0 (infra, platform, cnpg, vault, dbaas, external-secrets): local
  state with SOPS encryption in git — unchanged, required for bootstrap.
- Tier 1 (105 app stacks): PostgreSQL backend on CNPG cluster at
  10.0.20.200:5432/terraform_state with native pg_advisory_lock.

Motivation: multi-operator friction (every workstation needed SOPS + age +
git-crypt), bootstrap complexity for new operators, and headless agents/CI
needing the full encryption toolchain just to read state.

Changes:
- terragrunt.hcl: conditional backend (local vs pg) based on tier0 list
- scripts/tg: tier detection, auto-fetch PG creds from Vault for Tier 1,
  skip SOPS and Vault KV locking for Tier 1 stacks
- scripts/state-sync: tier-aware encrypt/decrypt (skips Tier 1)
- scripts/migrate-state-to-pg: one-shot migration script (idempotent)
- stacks/vault/main.tf: pg-terraform-state static role + K8s auth role
  for claude-agent namespace
- stacks/dbaas: terraform_state DB creation + MetalLB LoadBalancer
  service on shared IP 10.0.20.200
- Deleted 107 .tfstate.enc files for migrated Tier 1 stacks
- Cleaned up per-stack tiers.tf (now generated by root terragrunt.hcl)

216d4240c9 [infra] Add Cloudflare provider to all stack lock files and generated providers
Terragrunt now generates cloudflare_provider.tf (Vault-sourced API key)
and includes cloudflare in required_providers. These are the generated
files from running `terragrunt init -upgrade` across all stacks.

b1d152be1f [infra] Auto-create Cloudflare DNS records from ingress_factory
## Context

Deploying new services required manually adding hostnames to
cloudflare_proxied_names/cloudflare_non_proxied_names in config.tfvars —
a separate file from the service stack. This was frequently forgotten,
leaving services unreachable externally.

## This change:

- Add `dns_type` parameter to `ingress_factory` and `reverse_proxy/factory`
  modules. Setting `dns_type = "proxied"` or `"non-proxied"` auto-creates
  the Cloudflare DNS record (CNAME to tunnel or A/AAAA to public IP).
- Simplify cloudflared tunnel from 100 per-hostname rules to wildcard
  `*.viktorbarzin.me → Traefik`. Traefik still handles host-based routing.
- Add global Cloudflare provider via terragrunt.hcl (separate
  cloudflare_provider.tf with Vault-sourced API key).
- Migrate 118 hostnames from centralized config.tfvars to per-service
  dns_type. 17 hostnames remain centrally managed (Helm ingresses,
  special cases).
- Update docs, AGENTS.md, CLAUDE.md, dns.md runbook.

```
BEFORE                          AFTER
config.tfvars (manual list)     stacks/<svc>/main.tf
        |                         module "ingress" {
        v                           dns_type = "proxied"
stacks/cloudflared/               }
  for_each = list                     |
  cloudflare_record               auto-creates
  tunnel per-hostname             cloudflare_record + annotation
```

## What is NOT in this change:

- Uptime Kuma monitor migration (still reads from config.tfvars)
- 17 remaining centrally-managed hostnames (Helm, special cases)
- Removal of allow_overwrite (keep until migration confirmed stable)

- Fix woodpecker persistence config and alertmanager PV

Only Immich (8 PVCs, ~1.4TB) remains on TrueNAS.

f7c2c06009 right-size memory: set requests=limits based on actual usage
- Set memory requests = limits across 56 stacks to prevent overcommit
- Right-sized limits based on actual pod usage (2x actual, rounded up)
- Scaled down trading-bot (replicas=0) to free memory
- Fixed OOMKilled services: forgejo, dawarich, health, meshcentral,
  paperless-ngx, vault auto-unseal, rybbit, whisper, openclaw, clickhouse
- Added startup+liveness probes to calibre-web
- Bumped inotify limits on nodes 2,3 (max_user_instances 128->8192)

Post node2 OOM incident (2026-03-14). Previous kubelet config had no
kubeReserved/systemReserved set, allowing pods to starve the kernel.

b00f810d3d Remove all CPU limits cluster-wide to eliminate CFS throttling
CPU limits cause CFS throttling even when nodes have idle capacity.
Move to a request-only CPU model: keep CPU requests for scheduling
fairness but remove all CPU limits. Memory limits stay (incompressible).

Changes across 108 files:
- Kyverno LimitRange policy: remove cpu from default/max in all 6 tiers
- Kyverno ResourceQuota policy: remove limits.cpu from all 5 tiers
- Custom ResourceQuotas: remove limits.cpu from 8 namespace quotas
- Custom LimitRanges: remove cpu from default/max (nextcloud, onlyoffice)
- RBAC module: remove cpu_limits variable and quota reference
- Freedify factory: remove cpu_limit variable and limits reference
- 86 deployment files: remove cpu from all limits blocks
- 6 Helm values files: remove cpu under limits sections

1f2c1ca361 [ci skip] phase 5+6: update CI pipelines for SOPS, add sensitive=true to secret vars
Phase 5 — CI pipelines:
- default.yml: add SOPS decrypt in prepare step, change git add . to
  specific paths (stacks/ state/ .woodpecker/), cleanup on success+failure
- renew-tls.yml: change git add . to git add secrets/ state/

Phase 6 — sensitive=true:
- Add sensitive = true to 256 variable declarations across 149 stack files
- Prevents secret values from appearing in terraform plan output
- Does NOT modify shared modules (ingress_factory, nfs_volume) to avoid
  breaking module interface contracts

Note: CI pipeline SOPS decryption requires sops_age_key Woodpecker secret
to be created before the pipeline will work with SOPS. Until then, the old
terraform.tfvars path continues to function.

a1ba218cd2 [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

- Add Kyverno pod security policies in audit mode (privileged, host
  namespaces, SYS_ADMIN, trusted registries)
- Tighten rate limiting (avg=10, burst=50)

  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:

  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
