amazon-web-services - 使用 CloudFormation 和 AWS 控制台创建 ECS 集群时的不同行为

Question

使用CloudFormation创建时，没有缩放ECS实例按钮，要缩放实例，您需要找到Auto Scaling Group到缩放不是我想要的实例。

使用AWS 控制台创建时，有一个扩展 ECS 实例按钮。

我想在使用 CloudFormation 创建时有该按钮。

我错过了什么或者做错了什么吗？

Answer 1

更新:我在官方documentation找到了这个。

If your cluster was created with the console first-run experience after November 24th, 2015, then the Auto Scaling group associated with the AWS CloudFormation stack created for your cluster can be scaled up or down to add or remove container instances. You can perform this scaling operation from within the Amazon ECS console.

If your cluster was not created with the console first-run experience after November 24th, 2015, then you cannot scale your cluster from the Amazon ECS console. However, you can still modify existing Auto Scaling groups associated with your cluster in the Auto Scaling console.

引用号:Scaling Cluster

If a Scale ECS Instances button appears, then you can scale your cluster in the next step. If not, you must manually adjust your Auto Scaling group to scale up or down your instances, or you can manually launch or terminate your container instances in the Amazon EC2 console.
