amazon-web-services - Cloudformation 条件语句

Question

我正在尝试使用用于登录 ECS TaskDefination 的条件语句为 ECS 服务创建堆栈。我正在尝试根据环境将日志发送到不同的源，但在堆栈更新期间失败，如下所示。

错误资源处理程序返回消息:“模型验证失败(#/ContainerDefinitions/0/Memory:预期类型:Number，找到:String #/ContainerDefinitions/0/Cpu:预期类型:Number，找到:String #/ContainerDefinitions/0/LogConfiguration:预期类型:JSONObject，找到:JSONArray #/ContainerDefinitions/0/PortMappings/0/ContainerPort:预期类型:Number，找到:String)"

Conditions:
  HasDefaultLog:
    !Or [ !Equals [ !Ref EnvType, 'Prod' ], !Equals [ !Ref EnvType, 'Dev' ], !Equals [ !Ref EnvType, 'Sit' ] ]

ContainerDefinitions:
        - Name: !Ref 'ServiceName'
          Cpu: !Ref 'ContainerCpu'
          Memory: !Ref 'ContainerMemory'
          Image: !Ref 'ImageUrl'
          PortMappings:
            - ContainerPort: !Ref 'ContainerPort'
          LogConfiguration:
            -
              Fn::If:
                - HasDefaultLog
                -
                  LogDriver: !Ref LogDriver
                  Options:
                    syslog-address: !Ref LogDestination
                    tag:  !Ref ServiceName
                -
                  LogDriver: awsfirelens
                  Options:
                    Name: newlogdriver

下面的操作相同，并且能够在目标中查看日志

LogConfiguration:
  LogDriver: !Ref LogDriver
  Options:
    syslog-address: !Ref LogDestination
    tag:  !Ref ServiceName

Answer 1

LogConfiguration 是对象，而不是对象列表。 Sp 你不需要在开头 - :

          LogConfiguration:
              Fn::If:
                - HasDefaultLog
                -
                  LogDriver: !Ref LogDriver
                  Options:
                    syslog-address: !Ref LogDestination
                    tag:  !Ref ServiceName
                -
                  LogDriver: awsfirelens
                  Options:
                    Name: newlogdriver
