Finally, depending on your project, the language that you use may have good support for cross-compilation. In that case, multi-stage builds in Dockerfiles can be effectively used to build binaries for the platform specified with `--platform` using the native architecture of the build node. List of build arguments like `BUILDPLATFORM` and `TARGETPLATFORM` are available automatically inside your Dockerfile and can be leveraged by the processes running as part of your build.
