This repository holds the individual scripts used as steps within the xMatters workflow to automatically attempt to grow an AWS EBS volume based on a CloudWatch alarm triggering a SNS topic.
An article "Automated EBS expansion with xMatters" explains the workflow and the steps within the automation.
In addition to the steps, the jsSHA library from https://coursesweb.net/javascript/jssha-hash-hmac is required as a xMatters library for the workflow. A copy of the minimised code has been added to this repo to ensure that a copy is preserved. It is Copyright (c) 2008-2020 Brian Turek, 1998-2009 Paul Johnston & Contributors.
