kubernetes nodes automatically perform image garbage collection. You can find documentation on the default thresholds here: https://kubernetes.io/docs/concepts/cluster-administration/kubelet-garbage-collection/#user-configuration

You can tune these thresholds on your k3s nodes by adding arguments to the service command line: --kubelet-arg=image-gc-high-threshold=85 --kubelet-arg=image-gc-low-threshold=80

If for some reason you want to muck about with deleting things manually, you can try: sudo k3s crictl images to see what images have been pulled locally sudo k3s crictl rmi --prune to delete any images no currently used by a running container
