This allows you to see the overall resources without having to check for each region and each service.

When you close your AWS Account, it also helps you to see if there are any active resources left over.

if you have any active resources and terminate them before you close your account

Script

get-resources.sh

for region in `aws ec2 describe-regions --query 'Regions[].RegionName' --region us-west-1 --output text`
do
    echo "region = ${region}"
    aws resourcegroupstaggingapi get-resources --region ${region} --query 'ResourceTagMappingList[].ResourceARN';
done

For each region fetched by describe-regions, I use resourcegroupstaggingapi get-resources.
It's OK to do describe-regions at any region, so I've set it to us-west-1.

Prerequisites

aws cli is installed.

Usage

Run

export AWS_PROFILE=xxxx # Not necessary if you always set the default profile.
sh get-resources.sh

Output

region = eu-north-1
[]
region = ap-south-1
[]
region = eu-west-3
[]
region = eu-west-2
[]
region = eu-west-1
