使用CloudFormation将临时存储附加到Fargate服务-预期类型：JSONArray，找到：JSONObject

如何解决使用CloudFormation将临时存储附加到Fargate服务-预期类型：JSONArray，找到：JSONObject

我正在尝试将临时卷附加到我们在Fargate上运行的服务，以便它可以在将某些文件复制到S3之前生成一些文件。当我在没有卷信息的情况下启动服务时，将成功创建CloudFormation模板，并运行该服务。

但是，在放置音量参数时，它将失败并显示以下错误：

模型验证失败（＃/卷：预期类型：JSONArray，找到：JSONObject＃/ ContainerDefinitions / 0 / MountPoints：预期类型：JSONArray，找到：JSONObject＃/ ContainerDefinitions / 0 / PortMappings / 0 / ContainerPort：预期类型：找到的数字：字符串）

这是模板：

  LogGroup:
    Type: AWS::Logs::LogGroup
    Properties:
      LogGroupName: !Join ['/',[/ecs,!Ref Env,!Ref ServiceName]]

Outputs:
  ContainerSecurityGroup:
    Description: ContainerSecurityGroup
    Value: !Ref ContainerSecurityGroup

我在问题上搜索了高低，但未发现与该问题有关的任何内容。另外，在不附加卷时，ContainerPort参数可以很好地用作字符串。我还尝试过将类型从String更改为Number，但是在期望使用JsonArray的同时，仍会找到相同的JsonObject。

有人可以朝正确的方向扔我吗？

干杯！

解决方法

MountPoints应该是MountPoint的列表。因此，在您的情况下应该是（请注意-）：

          MountPoints:
            - ContainerPath: "/app"
              SourceVolume: !Ref VolumeName
