And we as developers keep improving the code as we find those bugs and as we implement new features (possibly adding new bugs too 😅).

### Small Errors Automatically Handled { #small-errors-automatically-handled }

When building web APIs with FastAPI, if there's an error in our code, FastAPI will normally contain it to the single request that triggered the error. 🛡

  // Timed Get
  // There are a few design constraints to consider
  // * We want to be responsive to small timeouts, unpark() has non trivial latency overheads (I
  //   have observed 12 micros on 64-bit linux systems to wake up a parked thread). So if the
  //   timeout is small we shouldn't park(). This needs to be traded off with the cpu overhead of

                    out.print("\"><b>");
                    out.print(name);
                    out.print("</b><br><small>");
                    out.print(f.length() / 1024 + "KB <br>");
                    out.print(sdf.format(new Date(f.lastModified())));
                    out.print("</small>");
                    out.println("</a>");
                }
            }
        }

```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)。

你可以在 [Docker 文档（Shell 与 Exec 形式）](https://docs.docker.com/reference/dockerfile/#shell-and-exec-form)中了解更多。

⛔️ Shell form:

```Dockerfile
# ⛔️ Не робіть так
CMD fastapi run app/main.py --port 80
```

Обов’язково завжди використовуйте exec form, щоб FastAPI міг коректно завершувати роботу та щоб були викликані [події тривалості життя](../advanced/events.md).

For example:
```shell

```

### Sample settings

Here are some (minimal) sample settings for development or experimentation:
