lambdash: AWS Lambda Shell Hack: New And Improved! · Alestic.com - A Personal AWS Blog by Eric Hammond
easier, simpler, faster, better Seven months ago I published the lambdash AWS Lambda Shell Hack that lets you run shell commands to explore the environment in which AWS Lambda functions are executed. I also posted samples of command output that show fascinating properties of the AWS Lambda runtime environment. In the last seven months, Amazon has released new features and enhancements that have ma
Persistence Of The AWS Lambda Environment Between Function Invocations · Alestic.com - A Personal AWS Blog by Eric Hammond
AWS Lambda functions are run inside of an Amazon Linux environment (presumably a container of some sort). Sequential calls to the same Lambda function could hit the same or different instantiations of the environment. If you hit the same copy (I don’t want to say “instance”) of the Lambda function, then stuff you left in the environment from a previous run might still be available. This could be u

A fantastic new and oft-requested AWS feature was released during AWS re:Invent, but has gotten lost in all the hype about AWS Lambda functions being triggered when objects are added to S3 buckets.

Exploring The AWS Lambda Runtime Environment · Alestic.com - A Personal AWS Blog by Eric Hammond
In the AWS Lambda Shell Hack article, I present a crude hack that lets me run shell commands in the AWS Lambda environment to explore what might be available to Lambda functions running there. I’ve added a wrapper that lets me type commands on my laptop and see the output of the command run in the Lambda function. This is not production quality software, but you can take a look at it in the alesti
AWS Lambda Walkthrough Command Line Companion · Alestic.com - A Personal AWS Blog by Eric Hammond
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,
