Executing Ruby code in AWS Lambda

Sun, 29 Nov 2015 18:41:59 +0000

AWS Lambda supports only Java, JavaScript & Python at the time of writing this post. I was wondering whether I can exploit the Lambda to execute chef’s knife commands on it since Lambda runs on a Linux container. Using simple python function I have identified that the code of the Lambda function gets copied to /var/task and executed from there.

I decided to custom build ruby as embedded platform similar to how chef-client or chefdk are distributed. My requirement is to execute knife commands and its uses embedded ruby version 2.1.0, hence I downloaded the source archive that specific version.
