kubernetes - heapster-controller.yaml错误-选择以下选项之一:[heapster eventer heapster-nanny eventer-nanny]

Question

尝试部署heapster-controller以使Heapster + Graphana + InfluxDB适用于Kubernetes。尝试使用heapster-controller.yaml文件进行ot部署时获取错误消息:

部署已经完成，但随后出现错误:

[root@node236 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
[root@node236 influxdb]#

显示失败容器的日志:

[root@node236 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]
[root@node236 influxdb]#

我可能在哪里出错？

任何反馈赞赏!

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将显示命名容器内“heapster”容器的日志。
