参考grafana官网文档：https://grafana.com/docs/grafana/latest/installation/?pg=docs
环境准备
- k8s集群
- k8s持久化存储卷1Gi（基于云存储）
安装
- 编写yml文件：
grafana.yaml

grafana的数据目录：
/var/lib/grafana,用于存储其数据库、用户、dashboard，所以创建了pvc挂载用于持久化。
不做持久化，当容器重启时前面的数据丢失。
- k8s部署
2.1 安装应用
kubectl apply -f grafana.yaml
2.2 本地端口映射
kubectl port-forward service/grafana 3000:3000
2.3 浏览器访问：localhost:3000
2.4 使用默认账号admin登录，密码同账号名
总结
- 仅做记录，后续备查。来源于官网文档，里面配的登录账号都是默认的，安全性较弱。
账号密码的配置，可使用k8s的secret，然后挂载到pod的环境变量。
关于容器的配置参考：
