Infrastructure:
- Stack now runs on K3s v1.34.6 HA (3 Hetzner CX33 nodes as managers)
- Traefik DaemonSet + hostNetwork replaces Caddy + ingress mesh
- All manifests in deploy-k3s/manifests/; Swarm config (deploy/) kept
temporarily for reference
Bug fixes surfaced during migration:
- Dockerfile: golang:1.24-alpine -> 1.25-alpine (go.mod requires 1.25)
- cache_service.go: remove sync.Once reassignment from inside Do()
callback (was causing 'unlock of unlocked mutex' fatal after
Redis Ping failure)
- router.go: relax CSP from 'default-src none' to 'default-src self'
+ allowlist fonts.googleapis.com so the marketing landing page CSS
actually loads in browsers
- deploy/scripts/deploy_prod.sh: use docker buildx with
--platform linux/amd64 so arm64 (Apple Silicon) dev machines produce
images runnable on x86_64 Hetzner nodes; fix array expansion under
set -u
- deploy/swarm-stack.prod.yml: fix secret source references to use
top-level aliases (the '\${X_SECRET}' form never actually resolved);
dozzle ports: long-form host_ip is rejected by Swarm, switched to
short-form (bound to 0.0.0.0 with UFW-based loopback restriction);
worker replicas 2 -> 1 (Asynq scheduler singleton)
- deploy-k3s/manifests/admin/deployment.yaml: probe path '/admin/' -> '/'
(Next.js serves at root; /admin/ returned 404 and killed pods);
startupProbe failureThreshold 12 -> 24
- deploy-k3s/manifests/pod-disruption-budgets.yaml: worker minAvailable
1 -> 0 (singleton)
- deploy-k3s/manifests/api/deployment.yaml: startupProbe failureThreshold
12 -> 48 (MigrateWithLock serializes across 3 replicas on first-boot;
real startup takes up to 240s)
- .gitignore: tighten 'api' -> '/api' (was matching deploy-k3s/manifests/api/
and admin/src/app/api/*, hiding legitimate files)
New files:
- deploy-k3s/manifests/traefik-helmchartconfig.yaml: DaemonSet +
hostNetwork override for k3s-bundled Traefik
- deploy-k3s/manifests/ingress/ingress-simple.yaml: plain Ingress
without TLS (CF Flexible SSL) and without middleware
- deploy-k3s/MIGRATION_NOTES.md: operator-facing migration log
Documentation:
- docs/deployment/ — full deployment book, 26 files, ~42k words:
- Part I Overview, infrastructure, orchestrator choice (Ch 0-2)
- Part II Networking, firewall, Cloudflare (Ch 3-4, 13)
- Part III Security, Traefik ingress (Ch 5-6)
- Part IV Services, DB, storage, secrets, registry (Ch 7-11)
- Part V Data flow, deploy process, observability, failures, runbook
(Ch 12, 14-17)
- Part VI Cost, Swarm postmortem, roadmap (Ch 18-20)
- Appendices: glossary, kubectl cheat sheet, file locations,
consolidated citations
- README.md: Production Deployment section replaced with pointer to
the book; Go version bumped to 1.25
