# PLATFORMS defines the target platforms for  the manager image be build to provide support to multiple
# architectures. (i.e. make docker-buildx IMG=myregistry/mypoperator:0.0.1). To use this option you need to:
# - able to use docker buildx . More info: https://docs.docker.com/build/buildx/
# - 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.
