amazon-web-services - AWS Cloudformation 向 lambda 函数添​​加多层

Question

我已通过 CloudFormation 向 Lambda 函数添​​加了一层。现在我需要在我的函数中再添加一层。基本上，我现有的 Lambda 函数需要两层。是否可以？我尝试搜索 AWS 文档，但没有看到。

Resources:
  LambdaLayer:
    Type: "AWS::Lambda::LayerVersion"
    Properties:
    CompatibleRuntimes:
    - python3.8
    Content:
    S3Bucket: !Sub "hello-${AWS::Region}"
    S3Key: !Sub "myapp/layer1.zip"
    LayerName: "layer1"

  LambdaFunction:
    Type: "AWS::Lambda::Function"
    Properties:
    Code:
    S3Bucket: hello
    S3Key: myapp/function.zip"
    FunctionName: "hello-function"
    Handler: "hello-function.lambda_handler"
    Layers:
    - !Ref LambdaLayer

Answer 1

是的，这可能吗？以与添加第一层相同的方式添加其他层，仅在资源名称后附加数字以区分它们:

Resources:
  LambdaLayer1:
    Type: "AWS::Lambda::LayerVersion"
    Properties:
    CompatibleRuntimes:
    - python3.8
    Content:
      S3Bucket: !Sub "hello-${AWS::Region}"
      S3Key: !Sub "myapp/layer1.zip"
    LayerName: "layer1"
  
  LambdaLayer2:
    Type: "AWS::Lambda::LayerVersion"
    ...
    LayerName: "layer2"

 LambdaFunction:
    Type: "AWS::Lambda::Function"
    Properties:
    Code:
      S3Bucket: hello
      S3Key: myapp/function.zip"
    FunctionName: "hello-function"
    Handler: "hello-function.lambda_handler"
    Layers:
    - !Ref LambdaLayer1
    - !Ref LambdaLayer2
