pod中执行 grafana-cli plugins install grafana-clock-panel 出现以下报错：

排查思路：
ping 地址发现没有ping，安装工具也失败，使用curl发现报无法解析地址，curl其他地址也无法解析.
查看/etc/resolv.conf
root@grafana-7486b9bc8c-dw52j:/usr/share/grafana# cat /etc/resolv.conf nameserver 192.168.0.2 search kube-system.svc.cluster.local svc.cluster.local cluster.local options ndots:5
将dns地址改为 2.2.2.2 即可正常安装插件
