显示失败容器的日志：

Error from server: a container name must be specified for pod heapster-v1.1.0-beta1-3082378092-t6inb, choose one of: [heapster eventer heapster-nanny eventer-nanny]

我可能哪里出错了？
感谢任何反馈！！

正确的语法是kubectl logs <pod> <container>。
在您的示例中，kubectl logs heapster-v1.1.0-beta1-3082378092-t6inb heapster --namespace=kube-system 将显示指定 pod 中 "heapster" 容器的日志。
非常感谢您的反馈。我认为我的问题在于 tls-certs。需要深入挖掘。
再次感谢！！
