在AWS Lambda中共享代码 [英] Sharing code in AWS Lambda

问题描述

在AWS Lambda函数之间共享代码的首选方式是什么?

What is the prefered way to share code between AWS Lambda functions?

我有这样的结构:

• 功能
  • a
    • node_modules
    • index.js
    • package.json
    • functions
      • a
        • node_modules
        • index.js
        • package.json
        • node_modules
        • index.js
        • package.json
        • node_modules
        • index.js
        • package.json

        这使每个函数都拥有自己的node_modules，我可以使用CLI打包整个程序.

        This let every function keep its own node_modules and I can package the whole thing with the CLI.

        但是需要共享的自定义代码呢?

        But what about custom code that needs to be shared?

        我可以require("../mylibrary")，但是package命令仍然不会包含它.

        I can require("../mylibrary") but the package command would still not include it.

        推荐答案

        如dmigo所述，Lambda层是可能的.这是一些使用Lambda层代码的 SAM 模板代码:

        As dmigo mentioned already it's possible with Lambda layers. Here is some SAM template code for using the Lambda Layer Code:

        Globals:
          Function:
            Runtime: nodejs8.10
        
        MyFunction:
            Type: AWS::Serverless::Function
            Properties:
                CodeUri: a/
                Handler: index.handler
                Layers:
                - !Ref MySharedLayer
        MySharedLayer:
            Type: AWS::Serverless::LayerVersion
            Properties:
                LayerName: SharedLayer
                Description: Some code to share with the other lambda functions
                ContentUri: layer/
                CompatibleRuntimes:
                    - nodejs8.10
                RetentionPolicy: Retain
