`kubectl-reap` is a kubectl plugin that deletes unused Kubernetes resources.
Supported resources:
| Kind | Condition |
| ----------------------- | ---------------------------------------------------------- |
| Pod | Not running |
| ConfigMap | Not referenced by any Pods or ReplicaSet |
| Secret | Not referenced by any Pods, ReplicaSet, or ServiceAccounts |
| PersistentVolume | Not satisfying any PersistentVolumeClaims |
| PersistentVolumeClaim | Not referenced by any Pods |
| Job | Completed |
| PodDisruptionBudget | Not targeting any Pods |

Since this plugin supports dry-run as described below, it also helps you to find resources you misconfigured or forgot to delete.
