如果您已经知道什么是"环境变量"以及如何使用它们，请随意跳到下面的下一节。

///

环境变量（也称为"env var"）是一种存在于 Python 代码之外、存在于操作系统中的变量，可以被您的 Python 代码（或其他程序）读取。

您可以在 shell 中创建和使用环境变量，而无需使用 Python：

//// tab | Linux、macOS、Windows Bash

<div class="termy">

```console
// 您可以创建一个名为 MY_NAME 的环境变量
$ export MY_NAME="Wade Wilson"

// 然后您可以与其他程序一起使用它，例如
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

# shellcheck disable=SC2120
exit_1() {
	cleanup

	echo "minio1 ============"
	cat /tmp/minio1_1.log
	echo "minio2 ============"
	cat /tmp/minio2_1.log

	exit 1
}

cleanup() {
	echo -n "Cleaning up instances of MinIO ..."
	pkill minio || sudo pkill minio
	pkill -9 minio || sudo pkill -9 minio
	rm -rf /tmp/minio{1,2}
	echo "done"
}

  )"
}

# concatenates all lines of a file
concat_lines() {
  if [ -f "$1" ]; then
    # Remove \r in case we run on Windows within Git Bash
    # and check out the repository with auto CRLF management
    # enabled. Otherwise, we may read lines that are delimited with
    # \r\n and produce $'-Xarg\r' rather than -Xarg due to word
    # splitting rules.

#!/usr/bin/env bash

echo "Running $0"

set -x

Aquí hay algunas ideas posibles:

* Un "Contenedor de Inicio" en Kubernetes que se ejecuta antes de tu contenedor de aplicación
* Un script de bash que ejecuta los pasos previos y luego inicia tu aplicación
    * Aún necesitarías una forma de iniciar/reiniciar *ese* script de bash, detectar errores, etc.

/// 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:
