Calling lambda from pre hook

[orjan]

Hi and thanks for an awesome plugin!

Is there a way to get hold of a reference to the new lambda so it can be called and verified from the pre hook? Like NewVersion is being passed in implementing-safe-aws-lambda-deployments-with-aws-codedeploy

Hey @orjan, thanks a lot for reaching out! I guess the question would be if you can figure out the Lambda Version resource logical name in serverless.yml, which I'm not sure it's possible. Taking a look at their docs, the version logical ID looks like this {normalizedFunctionName}LambdaVersion{sha256}, you could probably ask Serverless maintainers if you can somehow get the sha256 of a function in serverless.yml.
That said, you probably don't need the function version to execute the new code, you can simply invoke $Latest, which should match with the new version when you execute the pre hook.
