Delete Unattached AWS EBS Volumes

Updated 2 months ago by Totalcloud

Unused EBS volumes cost money.

There's a template already available in the web app for this use case. This workflow template helps you automate deleting unused AWS EBS volumes, saving you hours of effort as well as money.

Please find below the information on how this template works and how you can customize it according to your needs.

How Does This Template Work?

  1. Trigger node initiates the workflow every Monday at 9am.
  2. Resource node fetches all EC2 Volumes belonging to an AWS account and AWS region.
  3. Filter node filters out only those Volumes that are available.
  4. User Approval node sends an email to the recipient requesting to Approve or Reject the action (deleting) that follows.
  5. Action node, upon detecting Approve command, deletes all the filtered out EC2 Volumes.
  6. Notification node sends an email to the concerned team(s) or stakeholder(s) about the deletion of these volumes.
