Use RHEL cloud images as the baseline for built disk images.
Because RHEL base images are not publicly available, it is necessary to first
download the RHEL cloud image from the Red Hat Customer Portal and pass the
path to the resulting file to disk-image-create as the
The cloud image can be found at (login required): RHEL8: https://access.redhat.com/downloads/content/479/ver=/rhel—8/8.0/x86_64/product-software RHEL7: https://access.redhat.com/downloads/content/69/ver=/rhel—7/7.1/x86_64/product-downloads
Then before running the image build, define DIB_LOCAL_IMAGE (replace the file name with the one downloaded, if it differs from the example):
The downloaded file will then be used as the basis for any subsequent image builds.
For further details about building RHEL images, see the rhel-common and redhat-common element README files.
The RHEL 8 base image you have downloaded. See the element description above for more details.
