Coming from AWS CDK + CDK8s, pulumi stacks are kind of lost on me. As far as I understand, pulumi stacks are just environment specific configs, no differences in codebase., it all points to the same

index.ts

entry point. With CDK I was able to copy paste a class and change it's inputs to create an entirely different environment. With Pulumi I need to use multiple projects + envs and use stack references? (which seems weakly typed in terms of outputs)

You can absolutely have different stacks running on different codebases. For example, I've had a

Pulumi.prod.yaml

file associated with my

main

branch, and a

Pulumi.feature-xxx.yaml

for testing in my

feature/KEY-123_new_feature

branch
