## 🔒 Security Considerations

- ⚠️ Consider adding security options (no-new-privileges)
- ⚠️ Consider running as non-root user

## 📊 Resource Requirements

No resource limits configured

### Recommended Resources
- **Minimum RAM**: 512MB
- **Recommended RAM**: 1GB+
- **CPU**: 1 core minimum
- **Storage**: Varies by usage

### Resource Monitoring
Monitor resource usage with:
```bash
docker stats
```

## 🔍 Health Monitoring

⚠️ No health check configured
Consider adding a health check:
```yaml
healthcheck:
  test: ["CMD", "curl", "-f", "http://localhost:PORT/health"]
  interval: 30s
  timeout: 10s
  retries: 3
```

### Manual Health Checks
```bash
# Check container health
docker inspect --format='{{.State.Health.Status}}' CONTAINER_NAME

# View health check logs
docker inspect --format='{{range .State.Health.Log}}{{.Output}}{{end}}' CONTAINER_NAME
```

## 🚨 Troubleshooting

### Common Issues
**Service won't start**
- Check Docker logs: `docker-compose logs service-name`
- Verify port availability: `netstat -tulpn | grep PORT`
- Check file permissions on mounted volumes

**Can't access web interface**
- Verify service is running: `docker-compose ps`
- Check firewall settings
- Confirm correct port mapping

**Performance issues**
- Monitor resource usage: `docker stats`
- Check available disk space: `df -h`
- Review service logs for errors

### Useful Commands
```bash
# Check service status
docker-compose ps

# View real-time logs
docker-compose logs -f syncthing

# Restart service
docker-compose restart syncthing

# Update service
docker-compose pull syncthing
docker-compose up -d syncthing

# Access service shell
docker-compose exec syncthing /bin/bash
# or
docker-compose exec syncthing /bin/sh
```
