FastAPI가 정상적으로 종료(graceful shutdown)되고 [lifespan 이벤트](../advanced/events.md)가 트리거되도록 하려면, 항상 **exec** form을 사용하세요.

- Reverted graceful node shutdown to match 1.21 behavior of setting pods that have not yet successfully completed to "Failed" phase if the GracefulNodeShutdown feature is enabled in kubelet.

If you do not want pods to be marked terminated on node shutdown in...

### SIG OpenStack

- Openstack now supports the node shutdown taint. The taint is added when an instance is shutdown in openstack. ([#67982](https://github.com/kubernetes/kubernetes/pull/67982), [@zetaab](https://github.com/zetaab))
