I’m trying to create a Lambda that is triggered by modifications to an existing S3 bucket but can’t see a way to do this using V1.0-rc2. It works fine if the bucket doesn’t already exist as the deployment will create it for me but the issue I have is that I want to keep the lifecycle of the bucket separate to the lambda.

It would be great to hear if there is a way to work around this!

It’s not currently possible in the core framework (due to CFN behaviour), but **there is [a plugin for that!](https://github.com/matt-filion/serverless-external-s3-event)**.
