Finally getting into AWS after several years in Azure.
I have a CodePipeline set-up for a dotnet core lambda function.
Traditionally I have set-up build pipelines and then transformed the configuration files for each release stage. Azure has an in-built task under the release pipelines that substitutes defined variables with the variables in the configuration file you direct it. It also does transformation in that I can take a appsettings.release.json and save it as appsettings.json.
This is all done post build and right before binaries are deployed.
I am looking for the similar capability in CodePipeline. Ideally storing my runtime values in either environment variables or the SecretsManager.
