여기서는 Pydantic `Settings` 클래스 안에 config `env_file`을 정의하고, 사용하려는 dotenv 파일의 파일명을 값으로 설정합니다.

### `lru_cache`로 `Settings`를 한 번만 생성하기 { #creating-the-settings-only-once-with-lru-cache }

디스크에서 파일을 읽는 것은 보통 비용이 큰(느린) 작업이므로, 각 요청마다 읽기보다는 한 번만 수행하고 동일한 settings 객체를 재사용하는 것이 좋습니다.

하지만 매번 다음을 수행하면:

```Python
Settings()
```

`model_config` 屬性僅用於 Pydantic 的設定。你可以閱讀更多：[Pydantic：概念：設定](https://docs.pydantic.dev/latest/concepts/config/)。

在這裡我們在 Pydantic 的 `Settings` 類別中定義設定 `env_file`，並將其值設為要使用的 dotenv 檔名。

### 使用 `lru_cache` 只建立一次 `Settings` { #creating-the-settings-only-once-with-lru-cache }

從磁碟讀取檔案通常是昂貴（慢）的操作，所以你可能希望只做一次，然後重複使用同一個設定物件，而不是在每個請求都讀取。

但每次我們這樣做：

```Python
Settings()
```

都會建立一個新的 `Settings` 物件，而且在建立時會再次讀取 `.env` 檔。

- Endpoints resources created by the Endpoints controller now have a label indicating this.
  (Users creating Endpoints by hand _can_ also add this label themselves, but they ought
  to switch to creating EndpointSlices rather than Endpoints anyway.) ([#130564](https://github.com/kubernetes/kubernetes/pull/130564), [@danwinship](https://github.com/danwinship)) [SIG Apps and Network]
