Running Ruby Code in AWS Lambda

You can run Ruby on AWS Lambda via SCAR using, for example, the ruby:2.2.10-slim-jessie Docker image.

Usage in AWS Lambda via SCAR

You can run a container out of this image on AWS Lambda via SCAR using the following procedure:

1. Create the Lambda function

scar init -f scar-ruby.yaml

2. Execute the Lambda function with an script to run sample Ruby script

scar run -f scar-ruby.yaml -s run-ruby-script.sh

The first invocation will take a bit longer than the subsequent ones, where the container will be cached. You can modify the script and perform another scar run.

You can also run multiple concurrent invocations of this Lambda function to perform highly-parallel event-driven processing. See the SCAR Programming Model.
