    """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

    p = pipeline.CreatePipelineTemplate()
    params = pipeline.PipelineParameters(
        app_name=config.app_name,
        lambda_python_version=config.lambda_python_version,
        codebuild_image=codebuild_image,
        code_source=source,
    )
    output = p.create_template(params)
