Um das zu tun, verwenden Sie den Standard-Python-Typhinweis [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union):

/// note | Hinweis

Wenn Sie eine [`Union`](https://docs.pydantic.dev/latest/concepts/types/#unions) definieren, listen Sie den spezifischeren Typ zuerst auf, gefolgt vom weniger spezifischen Typ. Im Beispiel unten steht `PlaneItem` vor `CarItem` in `Union[PlaneItem, CarItem]`.

///

Vous pouvez y parvenir en utilisant [`AfterValidator` de Pydantic](https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator) à l’intérieur de `Annotated`.

/// tip | Astuce

Pydantic a aussi [`BeforeValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-before-validator) et d’autres. 🤓

Users of FlexVolume should move their workloads to CSI driver.

### Deprecation of klog specific flags

To simplify the code base, several [logging flags got marked as deprecated](https://kubernetes.io/docs/concepts/cluster-administration/system-logs/#klog) in Kubernetes 1.23.
The code which implements them will be removed in a future release, so users of those need to start replacing the deprecated flags with some alternative solutions.

## Deployment Kavramları { #deployment-concepts }

Aynı [Deployment Kavramları](concepts.md)nı bu kez container'lar açısından tekrar konuşalım.

1. 直接将 `main.py` 复制到 `/code`（没有 `./app` 目录）。

2. 使用 `fastapi run` 来运行单文件 `main.py` 中的应用。

当你把文件传给 `fastapi run` 时，它会自动检测这是一个单文件而不是包，并知道如何导入并服务你的 FastAPI 应用。😎

## 部署概念 { #deployment-concepts }

我们再从容器的角度讨论一些相同的[部署概念](concepts.md)。

容器主要是简化应用**构建与部署**流程的工具，但它们并不强制采用某种特定方式来处理这些**部署概念**，可选策略有多种。

**好消息**是，不同策略下都有方式覆盖所有部署概念。🎉

让我们从容器角度回顾这些**部署概念**：

* HTTPS
* 启动时运行
* 失败重启
* 复制（运行的进程数）

## Концепції розгортання { #deployment-concepts }

Поговорімо знову про деякі з тих самих [Концепцій розгортання](concepts.md) у термінах контейнерів.

Puedes lograr eso usando [`AfterValidator` de Pydantic](https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator) dentro de `Annotated`.

/// tip | Consejo

Pydantic también tiene [`BeforeValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-before-validator) y otros. 🤓

not be a move instruction at all, perhaps a clear or load.
Or it might correspond exactly to the machine instruction with that name.
In general, machine-specific operations tend to appear as themselves, while more general concepts like
memory move and subroutine call and return are more abstract.
The details vary with architecture, and we apologize for the imprecision; the situation is not well-defined.

### AWS

OpenAPI에서는 이를 `anyOf`로 정의합니다.

이를 위해 표준 Python 타입 힌트인 [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union)을 사용할 수 있습니다:

/// note

[`Union`](https://docs.pydantic.dev/latest/concepts/types/#unions)을 정의할 때는 더 구체적인 타입을 먼저 포함하고, 덜 구체적인 타입을 그 뒤에 나열해야 합니다. 아래 예제에서는 `Union[PlaneItem, CarItem]`에서 더 구체적인 `PlaneItem`이 `CarItem`보다 앞에 위치합니다.
