The AWS Lambda Walkthrough 2 uses AWS Lambda to automatically resize images added to one bucket, placing the resulting thumbnails in another bucket. The walkthrough documentation has a mix of aws-cli commands, instructions for hand editing files, and steps requiring the AWS console.
For my personal testing, I converted all of these to command line instructions that can simply be copied and pasted, making them more suitable for adapting into scripts and for eventual automation. I share the results here in case others might find this a faster way to get started with Lambda.
These instructions assume that you have already set up and are using an IAM user / aws-cli profile with admin credentials.
The following is intended as a companion to the Amazon walkthrough documentation, simplifying the execution steps for command line lovers. Read the AWS documentation itself for more details explaining the walkthrough.
