Docker Multi-Platform Builds

[naftulikay]

• Docker installation for Ubuntu
• tonistiigi/binfmt - required to use QEMU to compile for other architectures on Linux, run docker run --privileged --rm tonistiigi/binfmt --install all to set up

I'm currently using:

docker buildx build \
  --progress plain \ # show full output and don't collapse on subsequent steps
  --build-arg RUST_RUN_TESTS=false \ # skip tests
  --build-arg RUST_RUN_AUDIT=false \ # skip audit
  --platform linux/amd64 \ # or linux/arm64, or both via linux/amd64,linux/arm64
  -t naftulikay/fuzzydatetime:latest \
  .

And this builds for the given platforms without issue.

• [ ] When TARGETPLATFORM is undefined, in docker/build-scripts/lib/functions.rs within the .rustup_target function, use dpkg --print-architecture and use this to figure out the architecture if this is unspecified.
