Per the [note](https://github.com/nativefier/nativefier/pull/1122#discussion_r588922780) by @SuperSandro2000 in #1122 Docker will still cache files in intermediate layers if you delete them, so they'll still be part of the image. Only solution seems to be to delete them as you create them so they don't cache: Per https://stackoverflow.com/questions/53998310/docker-remove-file-from-intermediate-layer Co-authored-by: Sandro <sandro.jaeckel@gmail.com>
