"""Generate a cloudformation template for a starter CD pipeline.
This command will write a starter cloudformation template to
the filename you provide. It contains a CodeCommit repo,
a CodeBuild stage for packaging your chalice app, and a
CodePipeline stage to deploy your application using cloudformation.
You can use any AWS SDK or the AWS CLI to deploy this stack.
Here's an example using the AWS CLI:
\b
$ chalice generate-pipeline pipeline.json
$ aws cloudformation deploy --stack-name mystack \b
--template-file pipeline.json --capabilities CAPABILITY_IAM
