Create settings

First, cdk init.

tsas-cdk init

What your serverless application name? [hello-service-sls]hellosls
What your default region? [ap-northeast-1]
✅ All done!

Push dev stage parameters using file

tsas-cdk param put-all --stage dev

putting parameters...
done.

Push individual parameter, such as SaaS token.

tsas-cdk param put-single -s dev GitHubToken XXXXXXXXXXYYYYYYYYYYYY --secure

List app, e2e division parameters

tsas-cdk param list --stage dev
tsas-cdk param list --stage dev --division e2e
