Kubernetes日誌 - 如何獲取kube-system豆莢的日誌

Question

如何從kube-system豆莢獲取日誌？運行kubectl logs pod_name_of_system_pod不起作用：

λ kubectl logs kube-dns-1301475494-91vzs 
Error from server (NotFound): pods "kube-dns-1301475494-91vzs" not found 

下面是get pods輸出：

λ kubectl get pods --all-namespaces 

NAMESPACE  NAME            READY  STATUS RESTARTS AGE 
default  alternating-platypus-rabbitmq-3309937619-ddl6b 1/1  Running 1   1d 
kube-system kube-addon-manager-minikube      1/1  Running 1   1d 
kube-system kube-dns-1301475494-91vzs      3/3  Running 3   1d 
kube-system kubernetes-dashboard-rvm78      1/1  Running 1   1d 
kube-system tiller-deploy-3703072393-x7xgb     1/1  Running 1   1d 

Answer 1

使用命名參數去kubectl：kubectl --namespace kube-system logs kubernetes-dashboard-rvm78
