试图部署heapster-controller以使Heapster + Graphana + InfluxDB在Kubernetes中工作。收到错误消息，而尝试使用heapster-controller.yaml文件OT部署：heapster-controller.yaml错误 - 选择其中一个：[heapster eventer heapster-nanny eventer-nanny]
heapster-controller.yaml

部署进展顺利，但后来我得到错误：
[[email protected] influxdb]# kubectl get pods -o wide --namespace=kube-system NAME READY STATUS RESTARTS AGE NODE heapster-v1.1.0-beta1-3082378092-t6inb 2/4 RunContainerError 0 1m node262.local.net [[email protected] influxdb]#
显示失败容器的日志：
[[email protected] influxdb]# kubectl logs --namespace=kube-system heapster-v1.1.0-beta1-3082378092-t6inb 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] [[email protected] influxdb]#
我哪里可能会出错？
任何反馈appreaciated！

使用'kubectl describe pod ...'来了解更多关于哪个容器可能有问题。 – EmmEff
Heapster吊舱中有多个容器。要从吊舱获取日志，您需要指定要查看哪个容器。正确的语法是'kubectl logs [-f] [-p] POD [-c CONTAINER] [flags]'。如果没有容器当前没有运行，您还需要添加'-p'来访问先前容器（已终止）的日志。 –
