[rush] rush deploy fails with argon2 package missing in x86 docker build from ARM host

[jwatte]

Summary

I have a project that references argon2. I develop on an ARM host, but I build an x86_64 dockerfile from this ARM host.
(Using macos M3 macbook and docker on rosetta which is actually pretty great)

Unfortunately, the "rush deploy" bundles up the ARM version of the argon2 library, so when I try to run the bundled project inside the x86 docker image, it fails to find the module.

So, on MacOS, "rush deploy"

In Dockerfile, do something like:

FROM --platform=linux/amd64 node:20
COPY common/deploy /app/
...

It will now create a deployment that doesn't work, because Rush doesn't know how to build cross-platform node_modules.

The only work-around I can think of would be to install the entire Rush toolchain in the docker container and re-build all sources on the inside, which seems like quite an additional amount of work.

This is more an issue with the package than that is with the rush deploy command itself. Does that package provide a way to override the current platform that it installs binaries for, perhaps via an environment variable?
