# What does prune: true do on a Flux Kustomization?

Flux CD, Easy (Beginner), Concepts. https://k8wiz.com/uquiz/what-does-prune-true-do-on-a-flux-kustomization

- A. Deletes objects from the cluster once you remove them from the source
- B. Removes old revisions of the source artifact from source-controller's storage
- C. Deletes pods that are stuck in a failed state
- D. Removes unused container images from the nodes

**Answer:** Deletes objects from the cluster once you remove them from the source

**Explanation:** kustomize-controller keeps an inventory of the objects it applied. With prune enabled, an object that disappears from the source is deleted from the cluster on the next reconciliation. Without it, removed objects are left running.
