    * Essas "tags" são especialmente úteis para os sistemas de documentação interativa automática (usando OpenAPI).
* Todas elas incluirão as `responses` predefinidas.
* Todas essas *operações de rota* terão a lista de `dependencies` avaliada/executada antes delas.
    * Se você também declarar dependências em uma *operação de rota* específica, **elas também serão executadas**.

比较特别的是，在 **Kubernetes** 环境中运行时，您通常**不需要**使用多个工作进程，而是**每个容器运行一个 Uvicorn 进程**。不过，我会在本章节的后续部分详细介绍这一点。

///

## 多个工作进程

您可以使用 `--workers` 命令行选项来启动多个工作进程：

//// tab | `fastapi`

如果您使用 `fastapi` 命令：

<div class="termy">

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