 ### prune old images
 
-prune old images, execute on kubernetes host node
+prune orphan images, execute on kubernetes host node
 
 ```bash
 crictl rmi --prune
 ```
 
+### Prune ephemeral containerd data
+
+Useful when testing image‑cache behavior or forcing a full image repull on the next reconciliation.
+This removes all containerd state, including images, snapshots, and metadata.
+
+``` bash
+# Stop k3s service
+systemctl stop k3s
+
+# Remove all containerd data (images, snapshots, metadata)
+rm -rf /var/lib/rancher/k3s/agent/containerd
+
+# Start k3s service
+systemctl start k3s
+```
+
+After this, k3s will start with a completely clean containerd state, and all images will be pulled again as workloads reconcile.
+
 ### check system logs
 
 ```bash
