Description

The return values are limited to the following:

• SnapStartResponse
• SnapStartResponse.ApplyOn
• SnapStartResponse.OptimizationStatus
• Arn

In the use case of a Sam Template, if you do an AWS::Serverless::Function, it does an AWS::Lambda::Function under the covers. If you are using an image_function, each function builds an independent Container Image. If AWS::Lambda::Function allowed you to get the ImageUri, you could have a single function build the image, and additional functions refer back to the initial image, reducing build times.

Example:

  Function1:
    Type: AWS::Serverless::Function
    Properties:
      PackageType: Image
      CodeUri: funcCode
      ImageConfig:
        Command:
          - "app.lambda_handler1"
    Metadata:
      Dockerfile: funcCode/Dockerfile
      DockerTag: Function1
  Function2:
    Type: AWS::Serverless::Function
    Properties:
      PackageType: Image
      CodeUri: !GetAtt Function1.ImageUri
      ImageConfig:
        Command:
          - "app.lambda_handler2"
  Function3:
    Type: AWS::Serverless::Function
    Properties:
      PackageType: Image
      CodeUri: !GetAtt Function1.ImageUri
      ImageConfig:
        Command:
          - "app.lambda_handler3"
