There is a script to upload all supported image to OpenStack.
./hack/setup-openstack-images.sh
By default all images will be named machine-controller-${OS_NAME}
.
The image names can be overwritten using environment variables:
COREOS_IMAGE_NAME="coreos" UBUNTU_IMAGE_NAME="ubuntu" CENTOS_IMAGE_NAME="centos" ./hack/setup-openstack-images.sh
