Access to unpacked folders with docker-build

[AaronBuxbaum]

Hopefully there's an easy answer to this!

I'm trying to use the docker-build plugin on Yarn 3 -- it works really well, with the exception of one big issue. The workspace in question is a package, which means that it has files defined under package.json. Because of that, yarn pack returns only those files, meaning that I'm unable to do anything outside of manifests and the files in the package itself.

What I'm hoping for is a way to copy in the original code from my workflow; I can make a minimal docker image of dependencies with the excellent existing manifests folder, but I can't do anything that requires the source code, including building and testing. Any advice is appreciated.

--copy seemed like a possible answer here (though I don't think it's how it's intended to work), but that returns an "Invalid filename" error when passed a folder.

Anything here?
