예를 들어, 훅을 전송하는 도중에 kubelet이 재시작된다면,
Kubelet이 구동된 후에 해당 훅은 재전송될 것이다.
### 디버깅 훅 핸들러
### 훅 핸들러 디버깅
훅 핸들러의 로그는 파드 이벤트로 노출되지 않는다.
만약 핸들러가 어떠한 이유로 실패하면, 핸들러는 이벤트를 방송한다.
`PostStart`의 경우, 이것은 `FailedPostStartHook` 이벤트이며,
`PreStop`의 경우, 이것은 `FailedPreStopHook` 이벤트이다.
이 이벤트는 `kubectl describe pod <파드_이름>`를 실행하면 볼 수 있다.
다음은 이 커맨드 실행을 통한 이벤트 출력의 몇 가지 예다.
실패한 `FailedPreStopHook` 이벤트를 직접 생성하려면, [lifecycle-events.yaml](https://raw.githubusercontent.com/kubernetes/website/main/content/en/examples/pods/lifecycle-events.yaml) 파일을 수정하여 postStart 명령을 "badcommand"로 변경하고 이를 적용한다.
다음은 `kubectl describe pod lifecycle-demo` 실행을 통한 이벤트 출력 예시이다.
