AWS CodeDeploy：STRING_VALUE can not be converted to an Integer

Question

【以下的问题经过翻译处理】 使用AWS CodePipeline , 设置好Source、Build 并将`taskdef.json`和`appspec.yaml`传给 CodePipeline，部署操作`Amazon ECS (Blue/Green)`将失败并显示以下错误：
```
STRING_VALUE can not be converted to an Integer
```
这个报错未指定出现错误的位置，因此很难定位问题。

这里是两个文件的参考内容:
```
# appspec.yaml
version: 0.0
Resources:
  - TargetService:
      Type: AWS::ECS::Service

          ContainerPort: 3000
```

```

   ]
}
```

有什么思路可以定位问题吗?

Answer

【以下的回答经过翻译处理】 在“root level”上，CPU和memory应该是字符串，而您已经正确地处理了这一点。问题在于查看[ECS容器定义](https://docs.aws.amazon.com/zh_cn/AWSCloudFormation/latest/UserGuide/aws-properties-ecs-taskdefinition-containerdefinitions.html)时，容器部分的内存应该是一个整数。

```
       "name": "my-project",
       "memory": "512", << 应该是 "memory": 512
       "image": "01234567890.dkr.ecr.us-east-1.amazonaws.com/my-project:a09b7d81",

```
