하지만 `open()`은 `async`와 `await`를 사용하지 않습니다.

그래서 이벤트 핸들러 함수는 `async def` 대신 표준 `def`로 선언합니다.

### `startup`과 `shutdown`을 함께 { #startup-and-shutdown-together }

*시작*과 *종료* 로직은 연결되어 있을 가능성이 높습니다. 무언가를 시작했다가 끝내거나, 자원을 획득했다가 해제하는 등의 작업이 필요할 수 있습니다.

로직이나 변수를 함께 공유하지 않는 분리된 함수에서 이를 처리하면, 전역 변수에 값을 저장하거나 비슷한 트릭이 필요해져 더 어렵습니다.

그 때문에, 이제는 위에서 설명한 대로 `lifespan`을 사용하는 것이 권장됩니다.

with a service account may only reference secrets specified in the service account's secrets field. Kubernetes clusters are only affected if the ServiceAccount admission plugin and the `kubernetes.io/enforce-mountable-secrets` annotation are used together with ephemeral containers.

**Note**: This only impacts the cluster if the ServiceAccount admission plugin is used (most cluster should have this on by default as recommended in https://kubernetes.io/docs/reference/access-authn-authz...

这个函数执行 I/O（输入/输出）操作，需要“等待”内容写进磁盘。

但 `open()` 不使用 `async` 和 `await`。

因此，声明事件处理函数要使用 `def`，而不是 `async def`。

///

### `startup` 和 `shutdown` 一起使用 { #startup-and-shutdown-together }

启动和关闭的逻辑很可能是连接在一起的，你可能希望启动某个东西然后结束它，获取一个资源然后释放它等等。

在不共享逻辑或变量的不同函数中处理这些逻辑比较困难，因为你需要在全局变量中存储值或使用类似的方式。

因此，推荐使用上面所述的 `lifespan`。

そのため、ディスクへの書き込みを「待つ」必要がある I/O（入力/出力）が関わります。

しかし `open()` 自体は `async` や `await` を使いません。

したがって、イベントハンドラ関数は `async def` ではなく通常の `def` で宣言しています。

///

### `startup` と `shutdown` をまとめて { #startup-and-shutdown-together }

起動時とシャットダウン時のロジックは関連していることが多いです。何かを開始してから終了したい、リソースを獲得してから解放したい、などです.

共有するロジックや変数のない別々の関数でそれを行うのは難しく、グローバル変数などに値を保存する必要が出てきます。

そのため、現在は上で説明したとおり `lifespan` を使うことが推奨されています。

  * Rescheduler relies on taints, which were changed in a backward incompatible way. Rescheduler 0.3 shipped together with Kubernetes 1.6 understands the new taints and will clean up the old annotations, but Rescheduler 0.2 shipped together with Kubernetes 1.5 doesn't understand the new taints. In order to avoid eviction loop during 1.5->1.6 upgrade you need to either upgrade the master node atomically (for example by using...
