kubernetes - kubectl顶部节点无法工作，它显示: “error: You must be logged in to the server (Unauthorized)”

我尝试为ver1.12_rc.1部署k8s环境。
它包括一个主节点和两个节点。它们都是CentOS Linux版本7.4.1708(核心)。相关信息如下:

[root@bogon174 dashboard]# kubectl get pods -n kube-system

[root@bogon174 dashboard]# kubectl get nodes
NAME             STATUS     ROLES    AGE   VERSION
192.168.20.171   Ready      <none>   10d   v1.12.0-rc.1
192.168.20.172   NotReady   <none>   10d   v1.12.0-rc.1

我研究了先前的问题，但无法获得正确的解决方案。

最佳答案

版本1.12不再使用heapster，并且top命令尚未移植到新的指标系统。有一个github问题，以便顶部可以使用新的指标系统。

查看可用的选项，唯一的一个是heapster，但是不再使用heapster。

[iahmad@web-prod-ijaz001 ~]$ kubectl top node --help
Display Resource (CPU/Memory/Storage) usage of nodes.

The top-node command allows you to see the resource consumption of nodes.

Aliases:
node, nodes, no

Examples:
  # Show metrics for all nodes
  kubectl top node

  # Show metrics for a given node
  kubectl top node NODE_NAME

Options:
      --heapster-namespace='kube-system': Namespace Heapster service is located in
      --heapster-port='': Port name in service to use
      --heapster-scheme='http': Scheme (http or https) to connect to Heapster as
      --heapster-service='heapster': Name of Heapster service
  -l, --selector='': Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2)

Usage:
  kubectl top node [NAME | -l label] [options]
