Para que esto funcione, necesitas `pip install python-dotenv`.

///

### El archivo `.env` { #the-env-file }

Podrías tener un archivo `.env` con:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### Leer configuraciones desde `.env` { #read-settings-from-env }

Y luego actualizar tu `config.py` con:

//// tab | Pydantic v2

For this to work, you need to `pip install python-dotenv`.

### The `.env` file { #the-env-file }

You could have a `.env` file with:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### Read settings from `.env` { #read-settings-from-env }

And then update your `config.py` with:

/// tip | Совет

Чтобы это работало, вам нужно `pip install python-dotenv`.

///

### Файл `.env` { #the-env-file }

У вас может быть файл `.env` со следующим содержимым:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### Чтение настроек из `.env` { #read-settings-from-env }

Затем обновите ваш `config.py` так:

//// tab | Pydantic v2

#!/usr/bin/env bash

/// tip | Tipp

Damit das funktioniert, müssen Sie `pip install python-dotenv` ausführen.

### Die `.env`-Datei { #the-env-file }

Sie könnten eine `.env`-Datei haben, mit:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### Einstellungen aus `.env` lesen { #read-settings-from-env }

Und dann aktualisieren Sie Ihre `config.py` mit:

/// tip | Dica

Para isso funcionar, você precisa executar `pip install python-dotenv`.

///

### O arquivo `.env` { #the-env-file }

Você poderia ter um arquivo `.env` com:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### Ler configurações do `.env` { #read-settings-from-env }

E então atualizar seu `config.py` com:

//// tab | Pydantic v2

#!/usr/bin/env bash

# shellcheck disable=SC2120
exit_1() {
	cleanup

	echo "minio1 ============"
	cat /tmp/minio1_1.log
	cat /tmp/minio1_2.log
	echo "minio2 ============"
	cat /tmp/minio2_1.log
	cat /tmp/minio2_2.log
	echo "minio3 ============"
	cat /tmp/minio3_1.log
	cat /tmp/minio3_2.log

	exit 1
}

cleanup() {
	echo "Cleaning up instances of MinIO"
	pkill minio
	pkill -9 minio

 在这种情况下，您就不必担心这些。 🤷

### 前面步骤策略的示例

这将在**很大程度上取决于您部署系统的方式**，并且可能与您启动程序、处理重启等的方式有关。

以下是一些可能的想法：

* Kubernetes 中的“Init Container”在应用程序容器之前运行
* 一个 bash 脚本，运行前面的步骤，然后启动您的应用程序
     * 您仍然需要一种方法来启动/重新启动 bash 脚本、检测错误等。

/// tip

我将在以后的章节中为您提供使用容器执行此操作的更具体示例：[容器中的 FastAPI - Docker](docker.md){.internal-link target=_blank}。
