Solución de problemas

Problemas comunes

Conexión MySQL rechazada

# Check if MySQL is ready
docker-compose logs mysql | grep "ready for connections"

# Restart MySQL
docker-compose restart mysql

El evaluador no responde

# Check grader logs
docker-compose logs grader

# Verify certificates
docker-compose exec grader ls -la /etc/omegaup/ssl/

Errores del entorno de pruebas del corredor

# Check seccomp is disabled
docker-compose exec runner cat /proc/sys/kernel/seccomp/actions_logged

# Verify capabilities
docker-compose exec runner capsh --print

Rendimiento lento

# Increase Docker resources (Docker Desktop)
# Memory: 8GB+, CPUs: 4+

# Check resource usage
docker stats

Restablecer entorno

# Stop everything
docker-compose down -v

# Remove all containers
docker-compose rm -f

# Remove images
docker-compose down --rmi all

# Fresh start
docker-compose up -d --build
