How it works

make S3

Use the aws lambda invoke command to test deployed lambda function with a mock s3 PUT event. The command will print the log produced by the lambda function, which can also be seen in the AWS CloudWatch service.

The mock data can be found in input/input-s3.json. It is much like a demo, feel free to edit it.

Note: If you want to Read/Write the resource referred in the event, please make sure your do own them.
