# 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.yaml # Chart metadata
|
||||||
|

## 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

||||||

## 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
