We cannot have any RUN commands in the Windows stage when using docker buildx, which is why we were using the busybox-helper image. The purpose of the image was to contain a few things that we would obtain by running a few commands: - symlinks for the busybox binary - run vcredist_x64.exe which would also give us the vcruntime140.dll which is necessary for dig or httpd. There are alternatives to the commands above that can be achieved in a Linux stage as well: - we can create the symlinks in a Linux stage with ln -s. Copying them over to Windows will allow them to work just as well as if they were being copied over from a Windows image. The 'Files\' prefix issue to the symlink target still persists. - we can download the vcruntime140.dll directly, allowing us to skip the vcredist_x64.exe installation.
