kubectl get pods -n kube-system

kubectl describe pods/heapster-7ff8d6bf9f-zt6kw

明明有pod,但是无法查看详细信息

kubectl describe pod Error from server (NotFound):pods not found_kubernetes

必须得指定namespace,因为系统中存在多个namespace

kubectl describe pods/heapster-7ff8d6bf9f-zt6kw --namespace kube-system

kubectl describe pod Error from server (NotFound):pods not found_kubernetes_02
