Easiest way to replicate a lambda?

0

I have two lambdas now in production, and want to set up development copies of them to safely try out new code in. As far as I can tell, Lambda's don't have the built-in prod/dev multicopy capability that Alexa skills do, so it looks like I have to do this manually. Is there a shortcut for doing so? I see that it's possible to export lambda configurations as SAM and/or development package, but the best instructions I've found so far (https://aws.amazon.com/premiumsupport/knowledge-center/lambda-function-migration-aws-sam/) require bouncing the SAM through an S3 instance, and it seems to me that there should be a simpler solution. I can't be the only developer with this need...

The best way to do this is to create a CloudFormation template to create the Lambda function. That way you can deploy it as many times as you like in as many accounts as you like. Sure, it's a bit of extra work up front but it saves a bunch of effort later on.

    Probably good advice. It's another hoop fir a new AWS developer to learn to jump through, though. And it still seems it would have been trivial for AWS to build this into the lambda console... Oh well. So far, it seems like AWS has so many offerings that they can't spend enough time really polishing the UI or docs for any of them.

See this post from stack overflow, which seems the SAM config file can be exported and used with CloudFormation to duplicate the lambda function.
