如何在cloudformation yml中获取最新的lambda版本? [英] How to get the latest lambda version in cloudformation yml?

问题描述

我正在尝试引用

I'm trying to reference an edge lambda for cloudfront distribution in cloudformation.

我现在拥有的是:

          LambdaFunctionARN:
            Fn::GetAtt: [BasicAuthLambdaFunction,Arn]

但是我得到这个错误:

发生错误:GGGCloudFrontDistribution-该函数ARN必须引用特定的功能版本.(ARN必须以版本号.)

An error occurred: GGGCloudFrontDistribution - The function ARN must reference a specific function version. (The ARN must end with the version number.)

那么..是否有某种技术可以引用该函数的最新版本?

So.. is there some kind of technique to reference the latest version of the function?

推荐答案

您不能使用最新版本.您必须使用特定版本作为链接的文档:

You can't use the latest version. You have to use a specific version as the documentation you linked states:

您必须指定功能版本的ARN；您不能指定Lambda别名或$ LATEST.

You must specify the ARN of a function version; you can't specify a Lambda alias or $LATEST.

如果要在模板中创建Lambda函数，则还可以创建一个版本并使用该版本.

If you are creating the Lambda function in your template, you can also create a version and use that.

  BasicAuthLambdaFunctionVersion: 
    Type: "AWS::Lambda::Version"
    Properties:
      FunctionName:
        Ref: BasicAuthLambdaFunction
# ...
      LambdaFunctionARN:
        Fn::GetAtt: [BasicAuthLambdaFunctionVersion,Arn]

请注意，更新堆栈时，Lambda函数代码更改时将不会创建新版本.您必须通过将 BasicAuthLambdaFunctionVersion 的名称更改为 BasicAuthLambdaFunctionVersion2 或其他名称来手动创建和使用新版本.要自动执行此操作，您可以在使用模板之前使用脚本对其进行编辑.

Note that when updating the stack, a new version will not be created when the Lambda function code changes. You have to manually create and use a new version by changing the name of BasicAuthLambdaFunctionVersion to BasicAuthLambdaFunctionVersion2 or something else. To automate this, you can edit the template with a script before using it.

如果您使用的是无服务器框架，请查看:

If you are using the Serverless Framework, take a look at:
