Alternativamente, HTTPS podría ser manejado por un proveedor de la nube como uno de sus servicios (mientras que la aplicación aún se ejecuta en un contenedor).

## Ejecutar en el Inicio y Reinicios { #running-on-startup-and-restarts }

Normalmente hay otra herramienta encargada de **iniciar y ejecutar** tu contenedor.

Podría ser **Docker** directamente, **Docker Compose**, **Kubernetes**, un **servicio en la nube**, etc.
