One-click deployment CloudFormation template support

[zxkane]

I want to publish CDK application to CloudFormation template with assets to S3 with one-click deployment enabled.

Use Case

There still are some barriers for end users to apply/evaluate a CDK based solution(installing prerequisites tools, cloning AWS solution source, installing dependencies, configuring aws credential, finally deploying cdk application).

One-click deployment CloudFormation template would simplify the user experiences.

Currently the synthesized output CFN template is using CfnParameter for external assets that will be specified in deployment runtime. It's very difficult to fill those parameters properly with the assets information in a manual publishing.

Proposed Solution

I think the most of work already done in cdk deploy command, it always uploads assets and templates to cdk staging bucket, then create cloudformation stack with parameter values of assets from previous step.

The cdk tool impments a new command publish to publish the assets to S3 bucket then updated template with default values for asset parameters and publishing it to S3 bucket as well.

The publish command can specify s3 bucket with prefix for publishing the artifacts or use the cdk-staging-bucket as default bucket.

+1 , but make sure the published CFN template abstracts/hides the Asset cloudformation parameter strings. Nothing more confusing than trying to populate Assets parameters manually (defaults don't populate automatically in all contexts) or explaining to an end-user that Asset parameters fields do not need to be modified. At the very least, moving AssetParameters to a separate parameter group would help.
