Auto Scaling 组 EC2 实例启动失败

Question

我正在尝试将 CloudFormation 堆栈启动到运行 EC2 上的 ECS 服务。创建 Auto Scaling 组时我的堆栈创建失败，并且控制台 Activity 选项卡中的错误显示：

Status: Failed

Description: Launching a new EC2 instance. Status Reason: The requested configuration is currently not supported. Please check the documentation for supported configurations. Launching EC2 instance failed.

Cause: At 2020-10-26T23:47:46Z a user request update of AutoScalingGroup constraints to min: 1, max: 1, desired: 1 changing the desired capacity from 0 to 1. At 2020-10-26T23:47:48Z an instance was started in response to a difference between desired and actual capacity, increasing the capacity from 0 to 1.

我曾尝试使用我的 CFT，但到目前为止运气不佳。

根据您的参数默认值，您正在尝试在实例类型 (c6g.4xlarge) 需要基于 ARM 的 AMI。

尝试将 AMI 切换到 ami-0ea142bd244023692，它（在撰写本文时）是 Ubuntu Server 20.04
