  • Quick diagnosis
  • 1. Why n8n needs a dedicated HA blueprint?
  • 2. Pattern A – Load‑balanced stateless workers
    • 2.1 Architecture snapshot
    • 2.2 Docker‑Compose – split into focused services
      • Database service (PostgreSQL, 3‑node replica)
      • Redis queue (optional)
      • n8n worker definition
      • Persistent volume for the DB
    • 2.3 Nginx health‑check configuration
  • 3. Pattern B – PostgreSQL high‑availability (Patroni + etcd)
    • 3.1 Why a single primary is a SPOF
    • 3.2 ConfigMap – Patroni configuration (focus: DCS & bootstrap)
    • 3.3 StatefulSet – three Patroni pods (focus: storage)
    • 3.4 n8n connection string (no changes during failover)
  • 4. Pattern C – External object storage for binary data
    • 4.1 Why off‑load binaries
    • 4.2 Terraform – create an S3 bucket (focus: versioning & lifecycle)
    • 4.3 n8n environment variables for S3 storage
    • 4.4 On‑prem alternative – NFS shared volume (focus: PV definition)
  • 5. Pattern D – Multi‑region active‑passive disaster recovery
    • 5.1 Component matrix (single purpose)
    • 5.2 Logical replication – primary node setup
    • 5.3 Logical replication – DR node registration
    • 5.4 Subscription – DR pulls from primary
    • 5.5 DNS‑based failover (Route 53) – weight‑based record set
  • 6. Monitoring, alerting & auto‑remediation
    • Sample PrometheusRule (worker count)
  • 7. TL;DR – One‑page HA checklist
