Isso ainda é verdade.

Então, para poder ter **vários processos** ao mesmo tempo, tem que haver um **único processo escutando em uma porta** que então transmite a comunicação para cada processo de trabalho de alguma forma.

            Process process = new ProcessBuilder().command(args).start();
            CountDownLatch latch = new CountDownLatch(2);
            ByteArrayOutputStream stdout = connectStream(process.getInputStream(), latch);
            ByteArrayOutputStream stderr = connectStream(process.getErrorStream(), latch);

            process.waitFor(1, TimeUnit.MINUTES);

Bir container, **ana process** (komut/program) çalıştığı sürece çalışır.

Container'larda normalde **tek bir process** olur. Ancak ana process içinden subprocess'ler başlatmak da mümkündür; böylece aynı container içinde **birden fazla process** olur.

Ama **en az bir çalışan process olmadan** çalışan bir container olamaz. Ana process durursa container da durur.
