ec2shrink

An easier way to reduce the storage size for EC2

Prerequisites

Login to AWS CloudShell with Administrator Priviledges

Find the CloudShell ip and add it to your security group for the relevant EC2 instances

Use this command inside Cloud Shell to determine its IP:

curl http://checkip.amazonaws.com

This ip is not static unfortunately, and so you may need to update the security rules from time to time if you find you cannot reach your EC2 instances.

Install Package

Install ec2shrink

pip3 install ec2shrink

Usage

ec2shrink shrink --id <your-ec2-instance-id> --size <desired-new-size-in-GiB>
