3. 创建集群：
注意，创建集群时，务必连接VPN，否则会超时. 代理的配置请见笔记：Ubuntu下配置代理
minikube start --docker-env http_proxy=http://127.0.0.1:7890 --docker-env https_proxy=http://127.0.0.1:7890 --docker-env no_proxy=localhost,127.0.0.1,10.96.0.0/12,192.168.99.0/24,192.168.39.0/24

需要在Grafana中配置来自Prometheus的datasource，就可以创建pane进行可视化，并且导出数据了。但是这里仍然不包含fault injection的部分，需要找一个合适的故障注入工具。
