Thanks for contributing; I'm a bit on the fence on adding these currently, as there are no plans for docker to start building for these distros (and publish to download.docker.com).

That said, I'm looking at these Dockefiles, and IIUC, both these distros are a fork of / based on / really similar to the CentOS Dockerfiles, so I'm wondering how far you would be able to get with the already present build-args;

I see that DISTRO. SUITE. and BUILD_IMAGE can be overridden currently; the remaining differences I see are;

Loading the GPG keys;

RUN rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-* || true

Instead of the hard-coded (CentOS 9 / 10);

RUN rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
RUN rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial-SHA256

Perhaps changing the CentOS ones to use a wildcard would work; not sure if the || true is needed; that's worth checking

RUN rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-*

The second change appears to be the powertools repository (which was renamed in CentOS to erb I think?);

RUN dnf config-manager --set-enabled crb || dnf config-manager --set-enabled powertools || true

versus (CentOS);

RUN dnf config-manager --set-enabled crb

Perhaps it'd be ok to update the CentOS Dockerfile to do so if we add a comment describing that it's to allow re-purposing the Dockerfile for derrivatives, such as opencloudos or tencentos. For that one as well, it may be preferable to not have the || true if we can do without, e.g.;

# CentOS uses crb, but some derrivatives such as opencloudos and tencentos
# still use the old "powertools" name.
RUN dnf config-manager --set-enabled crb || dnf config-manager --set-enabled powertools
