If you check out the "task manager" or "system monitor" (or similar tools) in your operating system, you will be able to see many of those processes running.

And, for example, you will probably see that there are multiple processes running the same browser program (Firefox, Chrome, Edge, etc). They normally run one process per tab, plus some other extra processes.

         * Only kill local Gradle processes (classpath in checkout directory).
         * Not clean up global Gradle processes (i.e. classpath in ~/.gradle/...).

        /**
         * Run at the end of each build. Kill potentially leaked processes in the current build.

A container is running as long as the **main process** (command or program) is running.

A container normally has a **single process**, but it's also possible to start subprocesses from the main process, and that way you will have **multiple processes** in the same container.

But it's not possible to have a running container without **at least one running process**. If the main process stops, the container stops.

Este Proceso Administrador probablemente sería el que escuche en el **puerto** en la IP. Y transmitirá toda la comunicación a los worker processes.

Esos worker processes serían los que ejecutan tu aplicación, realizarían los cálculos principales para recibir un **request** y devolver un **response**, y cargarían cualquier cosa que pongas en variables en RAM.

Tener otro gestor de procesos dentro del contenedor (como sería con múltiples workers) solo añadiría **complejidad innecesaria** que probablemente ya estés manejando con tu sistema de cluster.

### Contenedores con Múltiples Procesos y Casos Especiales { #containers-with-multiple-processes-and-special-cases }

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.

### Memória por Processo { #memory-per-process }

## Репликация — процессы и память { #replication-processes-and-memory }

В приложении FastAPI, используя серверную программу (например, команду `fastapi`, которая запускает Uvicorn), запуск в **одном процессе** уже позволяет обслуживать нескольких клиентов одновременно.

Но во многих случаях вы захотите одновременно запустить несколько процессов‑воркеров.

### Несколько процессов — Воркеры { #multiple-processes-workers }

Wenn Sie mit **mehreren Prozessen** dasselbe API-Programm ausführen, werden diese üblicherweise als <abbr title="Arbeiter">**Worker**</abbr> bezeichnet.

### Workerprozesse und Ports { #worker-processes-and-ports }

**Only one process** in the server can be listening on a specific **port** in a specific **IP address**. There could be other processes listening on other ports in the same IP address, but only one for each combination of IP address and port.

TLS (HTTPS) uses the specific port `443` by default. So that's the port we would need.

### Container mit mehreren Prozessen und Sonderfälle { #containers-with-multiple-processes-and-special-cases }

Natürlich gibt es **Sonderfälle**, in denen Sie **einen Container** mit mehreren **Uvicorn-Workerprozessen** haben möchten.
