When working with declarative objects it should be possible to remove objects and get them pruned like having them described in the respository. This would also help when renaming objects within the repository - which actually needs a manual on the host for the old objects. This even could be a better solution for the problem described in

I just deleted a bunch of things in another team's namespace (:blush:). I'd would love to have this feature. I had been using dry-run in another context, but then forgot to check it again after switching contexts.
Is there any workaround for this? I want to prune resources within a single namespace only.
We're still working on improving prune, the current mechanism is broken enough that we don't recommend people us it.
Also look like it's been fixed recently.
Can someone confirm if this is implemented? I tried using this feature with kubectl 1.18.2, which has , yet as with previous versions kubectl it returned an error about pruning a nonNamespaced object of kind Namespace.
I assume the problem is that "Namespace" is a non-namespaced resource, and therefore is not filtered by namespace, so gets deleted by "prune". As a workaround it's possible to manually pass a (whitelist of resources allowed to be deleted), and not include "Namespace" in it: The list of resources is taken from .
Would wrapping this loop with achieve the same result?
