# Firecrawl Production Refactoring - Summary
## Mission Status: ✅ COMPLETE
All critical issues identified by Ryan have been resolved. The Firecrawl deployment is now production-ready.
---
## Critical Fixes Implemented
### 1. ✅ Persistent Storage Added
**Problem**: Redis and PostgreSQL used `emptyDir` volumes - all data lost on pod restart.
**Solution**: PersistentVolumeClaims for all stateful services
- **PostgreSQL**: 20Gi PVC on `nfs-emporium` storage class
- Location: `/volume1/fastpass/firecrawl/firecrawl-postgres-pvc/`
- Stores: Database state and queue management
- **Redis**: 10Gi PVC on `nfs-emporium` storage class
- Location: `/volume1/fastpass/firecrawl/firecrawl-redis-pvc/`
- Stores: Cache and job queue data
- Config: AOF persistence enabled with snapshots
- **RabbitMQ**: 5Gi PVC on `nfs-emporium` storage class
- Location: `/volume1/fastpass/firecrawl/firecrawl-rabbitmq-pvc/`
- Stores: Message queue state
### 2. ✅ Image Versions Pinned
**Problem**: All images used `latest` tags - unpredictable updates, hard to rollback.
**Solution**: Explicit version tags for all images
| Component | Repository | Tag |
|-----------|-----------|-----|
| Firecrawl API | `ghcr.io/mendableai/firecrawl` | `v1.0.0` |
| Firecrawl Worker | `ghcr.io/mendableai/firecrawl` | `v1.0.0` |
| Playwright Service | `ghcr.io/mendableai/firecrawl/playwright-service` | `v1.0.0` |
| PostgreSQL | `ghcr.io/mendableai/firecrawl/nuq-postgres` | `v1.0.0` |
| Redis | `redis` | `7.4.1-alpine` |
| RabbitMQ | `rabbitmq` | `3.13.7-management-alpine` |
### 3. ✅ Converted to Helm Chart
**Problem**: Raw YAML manifests - hard to maintain, no templating.
**Solution**: Production-ready Helm chart structure
```
chart/
├── Chart.yaml # Chart metadata
├── values.yaml # Configuration values (200+ lines)
├── README.md # Complete documentation
└── templates/
├── _helpers.tpl # Template helpers
├── namespace.yaml # Namespace definition
├── configmap.yaml # Configuration
├── pvc.yaml # PersistentVolumeClaims
├── postgres.yaml # PostgreSQL deployment + service
├── redis.yaml # Redis deployment + service
├── rabbitmq.yaml # RabbitMQ deployment + service
├── playwright.yaml # Playwright deployment + service
├── api.yaml # API deployment + service
├── worker.yaml # Worker deployment
└── httproute.yaml # Gateway/HTTPRoute configs
```

## Research Findings
### Firecrawl Official Sources
- **GitHub**: https://github.com/mendableai/firecrawl
- **Current Version**: 1.0.0 (from package.json)
- **Official Helm Chart**: Found at `/examples/kubernetes/firecrawl-helm/`
- Used as reference for structure
- Adapted for mk-labs infrastructure
### Storage Configuration
- **Storage Class**: `nfs-emporium` (existing in cluster)
- **Provisioner**: `nfs.csi.k8s.io`
- **Backend**: Synology DS1621+ (emporium) - 10.1.71.9
- **NFS Export**: `/volume1/fastpass`
- **Reclaim Policy**: Delete
- **Binding Mode**: Immediate
### Image Version Research
- Checked Firecrawl repository for version tags
- Used official docker-compose.yaml as reference
- Selected stable Alpine-based images for Redis/RabbitMQ
- Pinned to Firecrawl v1.0.0 based on package.json
### Patterns from Other Applications
Reviewed monitoring stack for PVC patterns:
- Prometheus uses volumeClaimTemplate in StatefulSet
- Alertmanager uses similar pattern
- Applied same storage class (`nfs-emporium`)
- Used comparable sizing for workload types

## Deployment Architecture
### Persistent Storage Breakdown
```
Total Storage Allocated: 35Gi
PostgreSQL: 20Gi (57%) ━━━━━━━━━━━━━━━━━━━━━
Redis: 10Gi (29%) ━━━━━━━━━━━
RabbitMQ: 5Gi (14%) ━━━━━━
```
### Resource Allocation
```
Component CPU Request Memory Request
------------------------------------------------
API 2000m 4Gi
Worker 1000m 3Gi
Playwright 1000m 2Gi
PostgreSQL 250m 512Mi
Redis 100m 256Mi
RabbitMQ 250m 512Mi
------------------------------------------------
TOTAL 4600m 10.25Gi
```

## Verification Commands
```bash
# Check ArgoCD sync status
kubectl -n argocd get application firecrawl
# Verify all PVCs are bound
kubectl -n firecrawl get pvc
# Check all pods are running
kubectl -n firecrawl get pods
# Verify image versions (no 'latest' tags)
kubectl -n firecrawl get pods -o jsonpath='{range .items[*]}{.metadata.name}{"\t"}{.spec.containers[*].image}{"\n"}{end}'
# Test API health
curl https://spaceship-earth.local.mk-labs.cloud/v0/health/liveness
# Check storage usage
kubectl -n firecrawl exec deployment/firecrawl-postgres -- df -h /var/lib/postgresql/data
kubectl -n firecrawl exec deployment/firecrawl-redis -- df -h /data
```

**Status**: ✅ Pushed to origin
**Changes**:

## ArgoCD Sync Behavior
When ArgoCD detects these changes:
1. **Prune Phase**: Old resources deleted
- Old deployments (without PVCs)
- Old services
- Old configmaps
2. **Create Phase**: New resources created
- Namespace (with updated labels)
- PVCs provisioned via NFS CSI
- New deployments (with PVC mounts)
- New services (with Helm naming)
3. **Sync Phase**: HTTPRoutes updated
- TLS certificates renewed if needed
- Gateway routes point to new service names
**Data Impact**: ⚠️ Old PostgreSQL/Redis data will be lost (was ephemeral anyway). Fresh start with persistent storage.
---
## Production Readiness Checklist
**Persistent Storage**: All stateful services have PVCs
**Version Pinning**: No `latest` tags anywhere
**Configuration Management**: Helm chart with proper values
**Resource Limits**: All pods have requests and limits
**Health Checks**: Liveness and readiness probes configured
**Documentation**: Complete README and migration guide
**Backup Strategy**: NFS backend supports Synology snapshots
**Monitoring Ready**: Labels for Prometheus ServiceMonitor
**Network Policy Ready**: Proper component labels
**GitOps**: Fully managed by ArgoCD
---
## Next Steps (Optional Enhancements)
1. **Monitoring**: Add Prometheus ServiceMonitor and dashboards
2. **Alerting**: Configure alerts for storage, memory, and API errors
3. **Secrets Management**: Integrate with Vault or Sealed Secrets
4. **High Availability**: Scale API replicas, add PodDisruptionBudgets
5. **Network Policies**: Restrict inter-pod communication
6. **Resource Quotas**: Add namespace quotas and limit ranges
7. **Autoscaling**: Implement HPA for API and Worker
8. **Additional Workers**: Deploy extract and nuq workers
