The deployment method for kubernetes cannot be completed

[lengcangche-gituhub]

I deploy cadvisor following the instructions in https://github.com/google/cadvisor/tree/master/deploy/kubernetes.
However, after "kustomize build "https://github.com/google/cadvisor/deploy/kubernetes/base?ref=${VERSION}" | kubectl apply -f -", I input "kubectl -n cadvisor get pods", the output is:
NAME READY STATUS RESTARTS AGE
cadvisor-6tmn5 0/1 ContainerCreating 0 97s

Then I input "kubectl -n cadvisor describe pods cadvisor-6tmn5", part of the output is:
Warning FailedCreatePodSandBox <invalid> kubelet (combined from similar events): Failed to create pod sandbox: rpc error: code = Unknown desc = failed to setup network for sandbox "7730077d97a7b82247f09092dd7ad98093abf2b9bcb5b6b784d04251354ae75e": plugin type="flannel" failed (add): loadFlannelSubnetEnv failed: open /run/flannel/subnet.env: no such file or directory

Then I input "kubectl -n cadvisor describe daemonsets.apps", the output is:
