Running Github Actions on CodeBuild: Comparing pricing, setting up with CDK and how to use secrets?

Last week we looked at using serverless, AWS CodeBuild runners for your CI/CD workflows with Github actions - this week, we're fullfilling on the promise of looking at the pricing of both options - and the result was a surprise for Raphael, who was back on the show again!
Afterwards, we look at two other questions we had last week:
How to set up pre-requisites with the AWS CDK?
We open source this project at (github.com/RaphaelManke/codeb...) so you can use it yourself.
Dive deep with live coding from Raphael that also experiments with using secrets within your CI/CD pipeline and making those available in your Github Actions Hosted CodeBuild Runners :-)
