⛔️ **Shell** form:

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

Make sure to always use the **exec** form to ensure that FastAPI can shutdown gracefully and [lifespan events](../advanced/events.md) are triggered.

You can read more about it in the [Docker docs for shell and exec form](https://docs.docker.com/reference/dockerfile/#shell-and-exec-form).
