aws-image

Purpose

Report the details about an Amazon EC2 AMI.

Syntax

Syntax: aws-image AMI

Example

I found the AMI of an Ubuntu image I was interested in by:

  1. Going to Amazon EC2 AMI Locator
  2. Sorting the table by Version, most recent first
  3. Copying the AMI for version 21.1 for region us-east1 Ubuntu AMI example
$ aws-image ami-0a4b1fdc2301bf1f1

Notes

  • This script uses the aws CLI and requires that you have installed it and set it up.
  • Yes, you could use the aws CLI directly to do the same thing but I find it easier to use the script and not have to worry about the syntax of the aws command. The filter parameter is especially cumbersome IMHO. The underlying command for the above example is: 
    aws ec2 describe-images --filter Name=image-id,Values=ami-0a4b1fdc2301bf1f1 --region us-east-1
    Do you want to remember that syntax? I don't! That's why I created the script!
  • aws-images is related script that's very useful.
