                echo -n "Restarting $DESC: "
                _stop
                sleep 1
                _start

                N=/etc/init.d/$NAME
                echo "Usage: $N {start|stop|restart|force-reload|status}" >&2
                exit 1
                ;;
esac
exit 0

and works like a charm!

but if restart the box (docker) and see if it is running I could see that does not run and no "apparently" error found.

netstat -na  

shows that no instance is running
