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。

在左侧导航栏，单击无状态。
在无状态页面，等待几分钟，单击刷新，容器组数量全部为1/1之后，表示应用部署完成。

3. 安装探针

回到容器服务控制台页面，单击左侧导航栏上方的图标。
在集群列表页面的左侧导航栏中，单击应用目录。
在应用目录页面，单击ack-ahas-pilot。
在ack-ahas-pilot的详情页面，单击创建。

4. 通过架构感知查看系统整体架构

复制应用高可用服务控制台地址，在Firefox浏览器打开新页签，粘贴并访问容器服务应用高可用服务控制台。
