[root@hdss7-200 nfs-volume]# ls

nfs目录中创建grafana数据目录：
[root@hdss7-200 ~]# mkdir /data/nfs-volume/grafana

访问页面，默认用户名密码都是admin：
点击设置里的Preferences，修改下时间和背景颜色，时间我们选用浏览器时间模式：
下面我们去安装grafana的插件，进入到grafana的容器中执行安装命令即可：
grafana-cli plugins install grafana-kubernetes-app grafana-cli plugins install grafana-clock-panel grafana-cli plugins install grafana-piechart-panel grafana-cli plugins install briangann-gauge-panel grafana-cli plugins install natel-discrete-panel
安装后其实就是在nfs的挂载目录下从官网下载并解压了一些zip包，当然你可以手动去官网下载后解压到这里，然后重启POD即可：
配置grafana数据源：
配置认证方式，选择证书认证，然后拷贝相关证书的内容进去即可：
配置plugins中的kubernetes，点击enable：
配置成功保存即可，稍等片刻，即可出图：
