List resources across all regions using the AWS CLI
Published: 2023.09.10 · 1 minute read
Today, I needed to list all AWS CloudFormation stacks across all locations under my account. It wasn’t as straightforward as I initially thought because the AWS CLI doesn’t have a single command to do that. The --region all global flag would be nice. Luckily, with a little bit of Bash scripting, we can get the job done.
List of all active regions#
The first part of the puzzle is to obtain the list of all active regions.
aws account list-regions --region-opt-status-contains ENABLED ENABLED_BY_DEFAULT
List resources in all regions#
The second part is to loop the output of the previous command using the command to list resources in a specific region. In my case, I needed to list CloudFormation stacks, which can be done with the following command:
for region in $(aws account list-regions --region-opt-status-contains ENABLED ENABLED_BY_DEFAULT --query "Regions[].{Region: RegionName}" --output text)
do
echo "Region: $region"
aws cloudformation list-stacks --region=$region
done
With just a few adjustments, you can replace aws cloudformation list-stacks with any other command for different types of resources. Allow me to provide you with some examples.
aws dynamodb list-tables- to list DynamoDB tablesaws lambda list-functions- to list Lambda functionsaws rds describe-db-instances- to list RDS databases
