waarschuwing
Never commit the .env file to version control. All values shown above are examples — replace them with your own secure values before deploying.
Applying Configuration Changes
After modifying the .env file, restart the affected services:
cd /opt/netrecon
# Restart all services
docker compose down && docker compose up -d
# Or restart a specific service
docker compose restart api-gateway
Service Ports
All services run behind the Nginx reverse proxy on ports 80/443. Internal service ports are not exposed by default:
| Service | Internal Port | Description |
|---|---|---|
| API Gateway | 8000 | Main API endpoint |
| Vault Server | 8001 | Secrets management |
| License Server | 8002 | License validation |
| Email Service | 8003 | SMTP relay |
| Notification Service | 8004 | Push notifications and alerts |
| Update Server | 8005 | Agent and probe updates |
| Agent Registry | 8006 | Agent enrollment and management |
| Warranty Service | 8007 | Hardware warranty lookups |
| CMod Service | 8008 | Configuration management |
| IPAM Service | 8009 | IP address management |
To expose a service port directly (not recommended for production), add it to the service's ports mapping in docker-compose.yml.
