无法使用CloudFormation向AWS Lambda函数添加代码

Question

我正在尝试创建云层堆栈.堆栈已正确部署.已创建Lambda函数,但代码未作为内联函数添加到函数中.

它说

您的Lambda函数"lambda_function"无法内联编辑,因为处理程序中指定的文件名与部署包中的文件名不匹配.

云形成代码:

  LambdaFunction:
    Type: "AWS::Lambda::Function"
    Properties:
      Code:
        ZipFile: !Sub |
          import json

          def lambda_handler(event,context):
              #Creating delete request
              ...

      Description: Lambda function.
      FunctionName: lambda_function
      Handler: lambda_function.lambda_handler
      Role : !GetAtt LambdaExecutionRole.Arn
      Runtime: python2.7
      Timeout: 5

Answer 1

index如果您指定内联代码,则处理程序的第一部分应始终如此.

如果通过在Code属性中指定ZipFile属性将源代码指定为内联文本,请将index.function_name指定为处理程序. http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-lambda-function.html

所以只需使用:

LambdaFunction:
    Type: "AWS::Lambda::Function"
    Properties:
      Code:
        ZipFile: !Sub |
          import json

          def lambda_handler(event,context):
              #Creating delete request
              ...

      Description: Lambda function.
      FunctionName: lambda_function
      Handler: index.lambda_handler
      Role : !GetAtt LambdaExecutionRole.Arn
      Runtime: python2.7
      Timeout: 5

注意index.lambda_handler而不是lambda_function.lambda_handler.
