```

⛔️ **Forma Shell**:

```Dockerfile
# ⛔️ No hagas esto
CMD fastapi run app/main.py --port 80
```

Asegúrate de siempre usar la **forma exec** para garantizar que FastAPI pueda cerrarse de manera adecuada y que [los eventos de lifespan](../advanced/events.md) sean disparados.

```

⛔️ **Shell** form:

```Dockerfile
# ⛔️ Tun Sie das nicht
CMD fastapi run app/main.py --port 80
```

Achten Sie darauf, stets die **exec** form zu verwenden, um sicherzustellen, dass FastAPI ordnungsgemäß heruntergefahren wird und [Lifespan-Events](../advanced/events.md) ausgelöst werden.

```

⛔️ Forma **Shell**:

```Dockerfile
# ⛔️ Não faça assim
CMD fastapi run app/main.py --port 80
```

Garanta que você sempre use a forma **exec** para assegurar que o FastAPI consiga encerrar graciosamente e que os [eventos de lifespan](../advanced/events.md) sejam disparados.

## Criar e Usar Variáveis de Ambiente { #create-and-use-env-vars }

Você pode **criar** e usar variáveis de ambiente no **shell (terminal)**, sem precisar do Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Você pode criar uma variável de ambiente MY_NAME com
$ export MY_NAME="Wade Wilson"

```

⛔️ **Shell** form:

```Dockerfile
# ⛔️ Don't do this
CMD fastapi run app/main.py --port 80
```

FastAPI'nin düzgün şekilde kapanabilmesi ve [lifespan event](../advanced/events.md)'lerinin tetiklenmesi için her zaman **exec** formunu kullanın.

Detaylar için [shell ve exec form için Docker dokümanlarına](https://docs.docker.com/reference/dockerfile/#shell-and-exec-form) bakabilirsiniz.

## Umgebungsvariablen erstellen und verwenden { #create-and-use-env-vars }

Sie können Umgebungsvariablen in der **Shell (Terminal)** erstellen und verwenden, ohne Python zu benötigen:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Sie können eine Umgebungsvariable MY_NAME erstellen mit

```Dockerfile
# ✅ 推荐
CMD ["fastapi", "run", "app/main.py", "--port", "80"]
```

⛔️ **Shell** 形式：

```Dockerfile
# ⛔️ 不要这样
CMD fastapi run app/main.py --port 80
```

务必使用**exec** 形式，以确保 FastAPI 可以优雅停机并触发[生命周期事件](../advanced/events.md)。
