# - have enable BuildKit, More info: https://docs.docker.com/develop/develop-images/build_enhancements/
# - be able to push the image for your registry (i.e. if you do not inform a valid value via IMG=<myregistry/image:<tag>> then the export will fail)
# To properly provided solutions that supports more than one platform you should use this option.
