Chaos带你快速上手混沌工程
1. 创建实验资源
在页面左侧，单击云产品资源下拉菜单，查看本次实验资源。
单击免费开通创建所需资源。
说明：
资源创建过程需要1~3分钟。完成实验资源的创建后，您可以在云产品资源列表查看已创建的资源信息，例如：IP地址、用户名和密码等。
2. 创建应用
- 点击右侧 图标，切换到远程桌面操作界面。
- 双击打开虚拟桌面的Firefox ESR浏览器，在RAM用户登录框中点击“下一步”，复制云产品资源列表中子用户密码，粘按CTRL+V把密码粘贴到密码输区，登陆子账户（后续在远程桌面里的粘贴操作均使用CTRL + V快捷键）。
- 复制容器服务ACK控制台地址，在FireFox浏览器打开新页签，粘贴并访问容器服务ACK控制台。
https://cs.console.aliyun.com/- 在集群页面，单击详情。
- 在左侧导航栏，单击无状态。
- 在无状态页面，单击使用YAML创建资源。
- 在创建页面，复制以下代码并粘贴到模板框中，然后单击创建。
