A Serverless v1.x plugin to auto update lambda function version for
[Lambda@Edge][link-lambda-edge] LambdaFunctionAssociations.

Amazon recently added a requirement to LambdaFunctionAssociations, where you can
no longer reference the arn+alias(or $LATEST) and are now required to
provide arn+version. This plugin handles appending on the version for you.
You just need to set your LambdaFunctionARNs equal to the
[logicalID][link-sls-resref] string and the plugin will take care of the rest.

Install

``bash $ npm install serverless-lambda-version --save-dev`

Add the plugin to your serverless.yml file:

`yaml plugins: - serverless-lambda-version`

`Usage`

Set your yml references LambdaFunctionAssociations[n].LambdaFunctionARNequal to the [logicalID][link-sls-resref] of your function.

`yaml functions: myfunction: handler: functions/myfunction/handler.myfunctionHandler

resources: Resources: CDN: Type: "AWS::CloudFront::Distribution" Properties: DistributionConfig: ... DefaultCacheBehavior: ... LambdaFunctionAssociations: - EventType: origin-request LambdaFunctionARN: MyfunctionLambdaFunction`

> :exclamation: Any LambdaFunctionARNs already set to arn+versionshould > be ignored by the plugin.

Cloudformation Output:

`json "LambdaFunctionAssociations": [ { "EventType": "origin-request", "LambdaFunctionARN": { "Fn::Join": [ "", [ { "Fn::GetAtt": [ "MyfunctionLambdaFunction", "Arn" ] }, ":", { "Fn::GetAtt": [ "MyfunctionLambdaFunctionOZWEIGtTFB4RTIGbHCEthNMa97ZkMRinlERrCc0", "Version" ] } ] ] } } ],``
