基于腾讯云API调用多个接口实现类似Packer打包镜像的效果

https://console.cloud.tencent.com/api/explorer?Product=cvm&Version=2017-03-12&Action=RunInstances

https://console.cloud.tencent.com/api/explorer?Product=cvm&Version=2017-03-12&Action=DescribeInstances

https://console.cloud.tencent.com/api/explorer?Product=cvm&Version=2017-03-12&Action=CreateImage

https://console.cloud.tencent.com/api/explorer?Product=cvm&Version=2017-03-12&Action=DescribeImages

https://console.cloud.tencent.com/api/explorer?Product=cvm&Version=2017-03-12&Action=TerminateInstances

RunInstances 创建用于打包的CVM，给UserData参数传入业务环境初始化的代码
DescribeInstances 查询CVM状态
CreateImage 等待STOPPED状态时制作镜像（我是在UserData业务代码末尾加了关机动作的，大致就是通过UserData完成业务环境初始化后关机，然后做镜像）
DescribeImages 等待镜像完成的过程中查询镜像状态从CREATING变成NORMAL
TerminateInstances 镜像制作完成后销毁机器
