/// note | Technical Details

An `async` task can only be cancelled when it reaches an `await`. If there is no `await`, the generator (function with `yield`) can not be cancelled properly and may keep running even after cancellation is requested.

Since this small example does not need any `await` statements, we add an `await anyio.sleep(0)` to give the event loop a chance to handle cancellation.

### 執行應用 { #run-the-app }

你可以執行應用：

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

然後前往 `/docs` 的 UI，你會看到 FastAPI 使用這些模型來「文件化」API，也會用它們來「序列化」與「驗證」資料。

#### Use Cases with Early Exit Code { #use-cases-with-early-exit-code }

There are some use cases with specific conditions that could benefit from the old behavior of running the exit code of dependencies with `yield` before sending the response.

| `minio_cluster_kms_request_success` | Number of KMS requests that succeeded.                                                   |
| `minio_cluster_kms_uptime`          | The time the KMS has been up and running in seconds.                                     |

- Adds feature gate `KubeletInUserNamespace` which enables support for running kubelet in a user namespace.
  
  The user namespace has to be created before running kubelet.
  All the node components such as CRI need to be running in the same user namespace.
