1. AWS CLIが使えるようにしておく
2. 使用するbucketにあらかじめポリシーを設定しておく→ドキュメント

実行

% for x in `aws ec2 describe-regions --output text --query 'Regions[*].RegionName'` ; do aws cloudtrail create-trail --name Default --s3-bucket-name j3tm0t0-audit --include-global-service-events --region $x ; aws cloudtrail start-logging --name Default --region $x ; done
