The way I’d do it is by doing:

  guix system docker-image config.scm

where ‘config.scm’ is something minimalist like
<https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/system/examples/bare-bones.tmpl>.

That gives you a Docker image in which ‘guix-daemon’ is running, and
thus you can do “docker run guix build” (roughly) to build things in
that image.  See
<https://guix.gnu.org/manual/devel/en/html_node/Invoking-guix-system.html>.

Would that work for you, Vincente?

Anyhow, thanks for sharing.  I’ve used Guix on top of a “foreign distro”
for CI, and I think it’s pretty useful in that context!
