KEP of the Week
KEP 3960: Introducing Sleep Action for PreStop Hook
This KEP proposes to add a "sleep" action for the Pod Lifecycle's PreStop and PostStart hooks. Before this KEP, for achieving the same result, users had to use the exec action and run the sleep command inside it. This required you to have a binary for the sleep command inside your image. Since this is a common usecase, this KEP proposed adding the sleep action as a first class citizen.
This KEP is targeting stable in the upcoming v1.32 release.
