```

### 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 linuxgsm-l4d2

# Restart service
docker-compose restart linuxgsm-l4d2

# Update service
docker-compose pull linuxgsm-l4d2
docker-compose up -d linuxgsm-l4d2
