无法使用 metrics得采集指令，kubectl top nodes ，无法使用

问题描述

在主机重启之后，metrics的相关操作均不可用，日志如下

问题分析

这里通过对各种的日志以及相关服务查看，发现其实是调取不到api，后来想到是不是网络的一些问题，然后还真的是，我这里的原因是 calico
实际得问题是，不值知道为什么，多了一个网卡，calico在初始化得时候，读取了这个虚拟网卡，而非主机得网卡，才会导致他无法与其他主机得pod进行通信！
大坑！

问题解决

保证集群网络可用我这里的bug就解决了
顺带提下，我这里是因为calico选择的并不是我的实际网卡问题导致的网络不可用
这里的是修改是制定了calico使用的网卡 em1

# 在配置文件指定网卡，这里是使用 em1
# 在env里面添加
- name: IP_AUTODETECTION_METHOD
  value: "interface=em1"

以上！
