This repository is sample implementation of cdk-remote-stack. cdk-remote-stack is a service that enables cross-stack references between regions, etc.
Check the repository below for details.
In this sample, I will use Budget Alert in us-east-1 region to refer to SNS Topic in ap-northeast-1 region.
If you have not yet configured bootstrap for each region, use the following command to do so. 123456789012 is a AWS account ID.
% npx cdk bootstrap aws://123456789012/ap-northeast-1 -c environment=dev
% npx cdk bootstrap aws://123456789012/us-east-1 -c environment=dev
% npx cdk deploy --all -c environment=dev --require-approval never
