Kubernetes 想要将pod与集群通信以运行一些kubectl命令

我试图从pod内部运行kubectl命令，以便与集群通信，并在通过延长的宽限期将pod保持在删除状态后，通过监视脚本删除--graceperiod=0的pod，以保持pod删除与prestop挂钩。但无法连接到群集IP，也无法ping pod本身

[root@pod01 /]# kubectl exec dnsutils cat /etc/resolv.conf
    Unable to connect to the server: dial tcp 196.19.0.1:443: connect: network is unreachable
[root@pod01 /]#   cat /etc/resolv.conf
    nameserver 196.19.0.2
    search namespace.svc.cluster.local svc.cluster.local cluster.local
    options ndots:5
[root@pod01 /]# kubectl exec -ti dnsutils -- nslookup kubernetes.default
    Unable to connect to the server: dial tcp 196.19.0.1:443: connect: network is unreachable

需要帮忙吗。？我无法运行其中任何一个来让pod在外部进行交互，我在CentOS 7上

网络组件在pod中处于终止状态，无法与群集通信。

我强烈建议您使用它们来寻址pod和服务，而不是像您现在使用的那样使用全局pod和服务。如果问题仍然存在，请更改并通知我。
