En particular, cuando corras en **Kubernetes** probablemente **no** querrás usar workers y en cambio correr **un solo proceso de Uvicorn por contenedor**, pero te contaré sobre eso más adelante en ese capítulo.

## Múltiples Workers { #multiple-workers }

Puedes iniciar múltiples workers con la opción de línea de comando `--workers`:

//// tab | `fastapi`

Si usas el comando `fastapi`:

In particular, when running on **Kubernetes** you will probably **not** want to use workers and instead run **a single Uvicorn process per container**, but I'll tell you about it later in that chapter.

///

## Multiple Workers { #multiple-workers }

You can start multiple workers with the `--workers` command line option:

//// tab | `fastapi`

If you use the `fastapi` command:

<div class="termy">

///

## Несколько воркеров { #multiple-workers }

Можно запустить несколько воркеров с помощью опции командной строки `--workers`:

//// tab | `fastapi`

Если вы используете команду `fastapi`:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:solid">main.py</u>

# 服务器工作进程（Workers） - 使用 Uvicorn 的多工作进程模式 { #server-workers-uvicorn-with-workers }

让我们回顾一下之前的部署概念：

* 安全性 - HTTPS
* 启动时运行
* 重新启动
* **复制（运行的进程数）**
* 内存
* 启动前的先前步骤

到目前为止，在文档中的所有教程中，您可能一直是在运行一个**服务器程序**，例如使用 `fastapi` 命令来启动 Uvicorn，而它默认运行的是**单进程模式**。

部署应用程序时，您可能希望进行一些**进程复制**，以利用**多核** CPU 并能够处理更多请求。

正如您在上一章有关[部署概念](concepts.md)中看到的，您可以使用多种策略。

在本章节中，我将向您展示如何使用 `fastapi` 命令或直接使用 `uvicorn` 命令以**多工作进程模式**运行 **Uvicorn**。

## Mehrere Worker { #multiple-workers }

Sie können mehrere Worker mit der `--workers`-Befehlszeilenoption starten:

//// tab | `fastapi`

Wenn Sie den `fastapi`-Befehl verwenden:

```console
$ <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:solid">main.py</u>

## Кілька працівників { #multiple-workers }

Ви можете запустити кілька працівників за допомогою параметра командного рядка `--workers`:
