Prefixing resource names with stack names (dev, prod etc) in the SAM template

Thanks Riku, Yes I am running sam deploy with codebuild, and I guess the approach you suggested requires manually editing the buildspec_deploy.yml? At first I thought the buildspec files are autogenerated based on the contents of the codepipeline.yaml so should not be modified manually as they would be overwritten next time. But now I can see the codepiple.yaml actually refers to the the buildspec file so I guess I was wrong about this. So please can you confirm, is it ok to manully edit the buildspec files to pass additional parameters when using it alongside codebuild, codepipeline.yaml etc? Also can you post an example to show how to let it pick up the stack name automatically as a parameter? I have dev and prod stacks and I guess I will have to access the stack name from without the codepipeline.yaml so that I can specify the stack name as a suffix to resource names (like the name of the dynamo db table)

It is possible to set environment variables in buildspec.yml. I think you can use this function to change the settings for each environment. In other words, I thought it would be a good idea to create a CodePipeline for each environment and create a branch for each environment. https://docs.aws.amazon.com/codebuild/latest/userguide/build-spec-ref.html#build-spec.env https://docs.aws.amazon.com/codebuild/latest/userguide/change-project-console.html#change-project-console-environment
