amazon-web-services - ECS 实例 AutoScalingGroup - 不稳定 - 扩展事件失败

Question

我想为具有自动扩展组的 AWS ECS 集群创建云形成脚本。

我尝试通过控制台创建相同的内容，然后从 AWS Cloud Formation 复制生成的 Cloud Formation 脚本。

然后我根据需要使用特定参数更改了它，当我上传脚本时，我收到以下错误和进程回滚。

集团并不稳定。 {当前/minSize/maxSize} 组大小 = {0/1/3}。扩展事件失败:可用区域没有默认子网:“ap-southeast-1b”。启动 EC2 实例失败。

Answer 1

发生此问题的原因是区域 ap-southeast-1 中没有可用的默认子网 ap-southeast-1b 。您能否检查该区域中是否存在默认 VPC 以及默认子网。如果其中任何一个被删除，那么您可以按照 link 中提到的步骤创建默认子网。 .
