### SIG Cluster Lifecycle

For 1.13 SIG Cluster Lifecycle is pleased to announce the long awaited promotion of kubeadm to stable GA, and the promotion of kubeadm’s configuration API to `v1beta1`.

그 다음에  `AsyncClient` 로 앱을 만들고 비동기 요청을 `await` 키워드로 보낼 수 있습니다:

{* ../../docs_src/async_tests/test_main.py hl[9:12] *}

위의 코드는:

```Python
response = client.get('/')
```

`TestClient` 에 요청을 보내던 것과 동일합니다.

/// tip | 팁

새로운 `AsyncClient`를 사용할 때 async/await를 사용하고 있다는 점에 주목하세요. 이 요청은 비동기적으로 처리됩니다.

* `seek(offset)`: Goes to the byte position `offset` (`int`) in the file.
    * E.g., `await myfile.seek(0)` would go to the start of the file.
    * This is especially useful if you run `await myfile.read()` once and then need to read the contents again.
* `close()`: Closes the file.

As all these methods are `async` methods, you need to "await" them.

For example, inside of an `async` *path operation function* you can get the contents with:
