Guidance/tips/tricks for developing CDK code that can synth CloudFormation templates that work with quick-create links

[ottokruse]

Q: Anyone know of guidance/tips/tricks for developing CDK code that can synth CloudFormation templates that work with quick-create links? Caveat: I need to include AWS Lambda functions that cannot be inlined into the template (too much code) so that need to packaged somehow.

It's not obvious to me how to do this because CDK assumes using its own deployment bucket to upload the Lambda sources to.
This is an example of such a quick-create link that is part of this blog.

We are doing exactly what you need in github.com/superwerker/superwerker.
Here's the build script: https://github.com/superwerker/superwerker/blob/main/.github/workflows/release.yml#L36-L53.
I order for that to work:

• your CDK stack/app needs to be environment agnostic
• you have to make sure Lambdas etc. are published to S3 buckets (in each region in the worst case, e.g. if you have AWS::Lambda::Function inside your templates, see here). Here's a script that publishes assets into the correct buckets. And here's the bucket creation script.
• a custom stack synthesizer that uses the S3 buckets from above

See the "quick install" link on the release page for reference: https://github.com/superwerker/superwerker/releases/tag/v1.1.0

Unfortunately all of this is a bit convoluted. The project above started as a YAML only Cloudformation project and we wanted to use CDK while also keeping it backwards compatible.

If anything is unclear, feel free to ask!
