Script for clean up app versions in AWS Elastic Beanstalk

readme.md

This code snippet removes old app versions in AWS Elastic Beanstalk. Only a specific amount of app versions should stay in the bucket.

In this example only the last 6 versions for prod environment and 3 for staging will be kept.
