List AWS Lambda@Edge log groups across regions

AWS Lambda@Edge functions, which run under CloudFront at multiple edge locations require associated Lambda functions to exist within each AWS region.

By design, this means CloudWatch Logs produced by Lambda@Edge functions will exist across these regions.

This Bash script will query for all log groups associated to Lambda@Edge functions for each enabled region of the current AWS account to hopefully help determine where logs are going/exist.

query.sh

#!/bin/bash -e

function main {
	local IFS=$'\n'
	local region
	for region in $(aws ec2 describe-regions --output text --query "Regions[].[RegionName]"); do
		echo "Region: $region"

		aws \
			--region "$region" \
				logs describe-log-groups \
					--log-group-name-prefix "/aws/lambda/us-east-1." \
					--output text \
					--query "logGroups[].[logGroupName]"
	done
}
