This looks similar to the internal pipelines framework that all of amazon uses to deploy code. Funny to see truly how much value amazon has gotten out of developing frameworks for the retail business, and then making those frameworks available publicly. The abstractions work because they have already been vetted across amazon for a decade

I think the last missing piece is getting reproducible builds which I think you can get from buildpacks [0], NixOS [1], or Bazel [2] running in your CodeBuild.

For all its complexity, brazil is amazing

There was actually an interesting blog post I saw on using content hashing with makefiles: https://andydote.co.uk/2022/09/19/make-content-hash/

I was thinking someone could probably build a manyrepo solution similar to Brazil on top of an idea like this. I don’t see many tools like Bazel built for manyrepos.

What am I missing that makes you feel that way about Brazil?

There’s no equivalent OSS implementation of a multi language lock file like Brazil’s. You have to build your own or go with a monorepo tool like bazel. Amazonians take reproducibility for granted because of Brazil.

You're talking "Bazel" right? No "r" pronounced like the herb "basil."

Or is there some other framework named "Brazil?"

Autocorrect gone viral?

Brazil is an internal tool used at Amazon.

NixOS is an equivalent and it does not require a mono repo.

I’d be happy if I’m wrong about this but I don’t think you can get a reproducible Node.JS build or python build from NixOS out the box. You need to build something on top of it.

It’s Terry Gilliam’s best work.

A deeply integrated build system with AWS would be very interesting.
