我从头开始编写了一个cloudformation JSON文件，但看起来有几个问题......
我观察到的基本上是2个问题。
Fisrt，我的ECS服务处于EC2启动类型，而不是FARGATE，这是仪表板所说的内容：
Status ACTIVE
Registered container instances 0
Pending tasks count 0 Fargate, 0 EC2
Running tasks count 0 Fargate, 0 EC2
Active service count 0 Fargate, 1 EC2
Draining service count 0 Fargate, 0 EC2
第二个问题是在cloudformation本身，它在服务CREATE_IN_PROGRESS停留数小时，然后它说服务＆＃34;无法稳定＆＃34;。
如果我了解FARGATE模式启用了什么，我们不需要创建AutoScalingGroup，也不需要创建LaunchConfiguration组件，对吧？
这是我的完整JSON：

要使用FARGATE启动类型，您需要在"LaunchType": "FARGATE"中指定EcsService。有关详细信息，请参阅the CloudFormation Documentation。
