Ergonomic, hermetic, user-friendly software build system for Python, Go, Java, Kotlin, Protobuf, Scala, Shell. Pants lets you fearlessly scale up your codebase!

Pants

and then we provide a standard Docker environment for those builds that only have our “base” libraries

This would be :100: as a built-in, to execute the build inside a given container, and even a layer to make it easy to run inside Kubernetes.

noting that the Docker image is for our wheelbuilder tool, not pants itself. so it’s more akin to a “pip install for the monorepo” that just puts prebuilt wheels in the right place for pants to consume. this helps obviate an entire host of at-build-time issues that can pop up when building sdists etc.

containerization is also not a solved problem for OSX, so we do our best and just build those locally on dev laptops

Agreed, the docker filesystem is sloooooooooooooow

longer term, we’re looking at remoting to solve the cross-platform build problem

but Docker + an emphasis on consumption of only bdists in the build has been a boon for our wheelbuilds/third party management
