Not creating for some reason with kubectl create yamls

for i in /var/lib/kubelet/pods /var/lib/kubelet/plugins_registry; do
echo $i
mkdir $i

Check status

kubectl create -f toolbox.yaml
kubectl -n rook-ceph exec -it $(kubectl -n rook-ceph get pod -l "app=rook-ceph-tools" -o jsonpath='{.items[0].metadata.name}') bash
