  blade [command]

Available Commands:
  create      Create a chaos engineering experiment  #create 创建一个chaos engineering
  destroy     Destroy a chaos experiment  #destroy 销毁一个destroy，一般销毁完之后，再执行revoke子命令
  help        Help about any command  #在任何子命令后输入help可查看该子命令的用法
  prepare     Prepare to experiment  #prepare 准备一个chaos engineering实验
  query       Query the parameter values required for chaos experiments  #查询已经注册的chaos
  revoke      Undo chaos engineering experiment preparation  #撤回注册chaos engineering
  status      Query preparation stage or experiment status  #查看注册的chaos engineering的状态
  version     Print version info

Flags:
  -d, --debug   Set client to DEBUG mode
  -h, --help    help for blade

Use "blade [command] --help" for more information about a command.

./blade create -h

Create a chaos engineering experiment

Usage:
  blade create [command]

Aliases:
  create, c

Examples:
create dubbo delay --time 3000 --offset 100 --service com.example.Service --consumer

Available Commands:
  cpu         Cpu experiment   #cpu负载测试，还可以指定负载在哪个cpu上
  disk        Disk experiment   #disk负载测试，支持disk的read/write负载模拟，还支持模拟磁盘填充
  docker      Execute a docker experiment   #docker负载测试，支持docker的cpu、disk、network、process、remove、script等负载测试
  druid       Druid experiment   #支持druid连接池的连接满模拟
  dubbo       dubbo experiment   #支持dubbo的延迟、连接池满、异常模拟
  jvm         method   #这个支持的就多了，下面细聊
  k8s         Kubernetes experiment   #k8s负载测试，支持k8s的同期的删除测试
  mysql       mysql experiment   #支持mysql的延迟、异常模拟
  network     Network experiment   #network负载测试，支持网络的延迟、dns查询延迟、丢包、远程服务丢失等场景
  process     Process experiment   #process负载测试，支持模拟kill process的场景
  script      Script chaos experiment
  servlet     java servlet experiment   #支持servlet的延迟、异常模拟

Flags:
  -h, --help   help for create

Global Flags:
  -d, --debug   Set client to DEBUG mode

{"code":200,"success":true,"result":"command: network delay --exclude-port 22 --debug false --help false --interface eth0 --time 10000"}

    先查询id

./blade status --type prepare

	"code": 200,
	"success": true,
	"result": [
		{
			"Uid": "2679c66005a0aadd",

			"UpdateTime": "2019-06-10T16:32:05.907016597+08:00"
		}
	]
}

    再撤销

./blade revoke 2679c66005a0aadd
