The deployment method for kubernetes isn't effective

[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 -", there is no pod for cadvisor.

Additionally, the output is:

Warning: 'commonLabels' is deprecated. Please use 'labels' instead. Run 'kustomize edit fix' to update your Kustomization automatically.
namespace/cadvisor created
serviceaccount/cadvisor created
daemonset.apps/cadvisor created

Hello, that's strange. Could you give me output of kubectl -n cadvisor get pods ?

λ ~/ echo $VERSION

Could you give me output of kubectl -n cadvisor describe daemonsets.apps ?

Another strange thing: I haven't do anything, and this time I input "kubectl -n cadvisor get pods", the output is：
NAME READY STATUS RESTARTS AGE
cadvisor-6tmn5 0/1 ContainerCreating 0 97s

However, I input "kubectl -n cadvisor get daemonsets.apps", the output is:

and I input "kubectl -n cadvisor describe pods cadvisor-6tmn5", part of the output is:
