Question

使用 CloudFormation 创建时，没有Scale ECS Instances按钮，要缩放您需要找到 Auto Scaling组以扩展实例的实例，不是我想要的。

使用 AWS控制台创建时，会出现Scale ECS Instances按钮。

我希望在使用CloudFormation创建时拥有该按钮。

我遗漏或做错了什么？

Answer 1

更新：我在官方documentation中找到了这个。

如果您的群集是在2015年11月24日之后使用console first-run experience创建的，则与之关联的Auto Scaling组   可以扩展为群集创建的AWS CloudFormation堆栈   或者向下添加或删除容器实例。你可以执行此操作   从Amazon ECS控制台中进行扩展操作。

如果您的群集未在2015年11月24日之后使用控制台首次运行体验创建，那么您无法扩展   来自Amazon ECS 控制台的群集。但是，您仍然可以修改   Auto中与您的群集关联的现有Auto Scaling组   扩展控制台。

参考：Scaling Cluster

如果出现Scale ECS Instances按钮，则可以缩放您的集群在下一步。如果没有，您必须手动调整自动缩放组可以向上或向下扩展实例，也可以手动进行在Amazon EC2中启动或终止容器实例控制台。

Answer 2

更新：如果您的集群未在2015年11月24日之后使用控制台首次运行体验创建，那么您无法从Amazon ECS控制台扩展集群。

ORIGINAL：

这只是一步一步解释如何获取按钮，您需要在CloudFormation模板中反映这一点。

创建一个空的ECS群集，例如 my-test-cluster
转到CloudFormation，使用模板创建名为 EC2ContainerService-my-test-cluster 的堆栈
模板可能需要具有以下内容

Outputs:
  TemplateVersion:
    Value: '2.0.0'
  UsedByECSCreateCluster:
    Value: 'true'

使用CloudFormation和AWS Console创建ECS群集时的不同行为
