Is it possible to modify a Kubernetes pod descriptor postponing the restart to a later event?
Basically I want to defer the changes to scheduled restart event.
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.
You cannot. That is not a feature of Kubernetes.
