【问题描述】：
kubernetes 的新手，但设法安装了 kubernetes、ubuntu 20.04 LTS，但仪表板有问题。按照程序，使用法兰绒作为CNF。
日志指出与 10.96.0.1:443 的连接存在问题，但 telnet 似乎可以工作？有什么建议可以走得更远吗？

【问题讨论】：
-
从另一个 pod telnet 到该 IP 和端口是否有效？
-
这个 Pod 的事件中有什么？ (
kubectl describe pod kubernetes-dashboard-7f99b75bf4-lfqtf)10.96.0.1是某个服务的地址吗？ -
IP 只是为了尝试错误： dial tcp 10.96.0.1:443: i/o timeout describe does not give any: bwa@prod3:~$ kubectl describe kubernetes-dashboard-7f99b75bf4-lfqtf错误：服务器没有资源类型“kubernetes-dashboard-7f99b75bf4-lfqtf”bwa@prod3:~$ kubectl describe pod kubernetes-dashboard-7f99b75bf4-lfqtf 服务器错误（未找到）：pods“kubernetes-dashboard-7f99b75bf4 -lfqtf" 未找到 bwa@prod3:~$

@bwa，解决这个问题有什么进展吗？向您的问题添加任何其他信息（尤其是代码示例、命令输出等）时，请使用edit 选项，而不是在 cmets 中发布。它更具可读性。请注意，您的 pod 部署在
kubernetes-dashboard命名空间中，因此您需要将--namespace=kubernetes-dashboard选项添加到kubectl describe pod <pod_name>，与运行kubectl logs命令时的方式相同。
