Next, you would run the server passing the configurations as environment variables, for example you could set an `ADMIN_EMAIL` and `APP_NAME` with:

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip | 팁

하나의 명령에 여러 env var를 설정하려면 공백으로 구분하고, 모두 명령 앞에 두세요.

///

그러면 `admin_email` 설정은 `"deadpool@example.com"`으로 설정됩니다.

`app_name`은 `"ChimichangApp"`이 됩니다.

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip

要為單一指令設定多個環境變數，只要用空白分隔它們，並全部放在指令前面即可。

///

如此一來，`admin_email` 設定會被設為 `"deadpool@example.com"`。

`app_name` 會是 `"ChimichangApp"`。

legacy_request_state_context_var: ContextVar[Optional[Dict[str, Any]]] = ContextVar(
    "legacy_request_state_context_var", default=None
)

async def set_up_request_state_dependency():
    request_state = {"user": "deadpond"}
    contextvar_token = legacy_request_state_context_var.set(request_state)
    yield request_state
    legacy_request_state_context_var.reset(contextvar_token)
```

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip | 豆知識

1つのコマンドに複数の環境変数を設定するには、スペースで区切ってコマンドの前に並べます。

///

すると、`admin_email` の設定は `"deadpool@example.com"` に設定されます。

`app_name` は `"ChimichangApp"` になります。

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip | 提示

要为单个命令设置多个环境变量，只需用空格分隔它们，并把它们都放在命令前面。

///

然后，`admin_email` 设置将为 `"deadpool@example.com"`。

`app_name` 将为 `"ChimichangApp"`。
