如何在不重启的情况下修改 K8s pod 描述符?

How modify a K8s pod descriptor without restarting it?

是否可以修改 Kubernetes pod 描述符以将重启推迟到以后的事件?

基本上我想推迟对预定重启事件的更改。

你不能。这不是 Kubernetes 的特性。

Pod Presets can work for cases where you want to inject additional configuration in the pod specification at creation time. Think of them as templates / blueprints that are used to inject additional configuration in the pods that match the specified labels, at creation time. You can have a look at some use cases here.
