ChaosBlade可针对多达7个场景开展故障注入实验，但网上官方的中英文文档质量欠佳，内容缺失，真心没有站在一般用户的角度来写，只能通过运行blade命令的help了解究竟有什么功能。

一句话介绍
ChaosBlade是阿里巴巴开源的针对7个检验软件系统稳定性场景的混沌工程故障注入开源工具：主机基础资源、CRI容器、K8S平台、Java应用、C++应用、阿里云平台、其他服务。
关键特性
以下关键特性，是我下载ChaosBlade v1.7.2，在运行blade时带上help参数，一点点试出来的。官网github的readme文档并没有写这么细。
场景1：主机基础资源
可注入故障包括CPU负载爆满，磁盘占用和读写爆满，内存爆满，网络延迟/丢包/坏包/乱序，端口被占用，DNS配置错误，杀进程。
场景2：CRI容器
可注入故障包括向容器内的基础资源注入故障，删除容器，以及向容器内各种服务注入故障。
场景3：K8S平台
可注入故障包括向K8S平台内容器、node和pod注入故障。
场景4：Java应用
可注入故障包括代码缓存爆满，内存不足，增加延迟，返回特定值，动态执行脚本，抛异常等。
场景5：C++应用
可注入故障包括增加延迟，运行中修改变量值，返回错误。
场景6：阿里云平台
可注入故障包括卸载磁盘，挂载或卸载网络接口等。
场景7：其他服务
可注入故障包括增加延迟和抛异常，可以针对如elastic search, hbase, http, mongodb, mysql等近30种服务注入故障。
具体特性，可以参考文后我根据命令行help输出，整理的特性列表。需要对里面的英文语法错误保持宽容态度。
适用平台
主机，CRI容器，K8S平台，Java应用，C++应用，阿里云平台，其他服务。
适用场景
需要向主机、CRI容器、K8S平台、阿里云平台、Java应用和C++应用注入故障的场景。
优势
支持多达7个故障注入场景。
劣势
网上的中英文文档描述过于简略。每个功能往往就一句话。只能把工具装上，运行起来，通过help参数，逆向工程来发现有什么功能。
案例
国内有金融行业的用户，已经基于ChaosBlade开发了混沌工程工具平台，在测试环境注入故障，检验基础设施和容器平台的稳定性。
