The way I=E2=80=99d do it is by doing:

  guix system docker-image config.scm

where =E2=80=98config.scm=E2=80=99 is something minimalist like
<https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/system/examples/bare-b=
ones.tmpl>.

That gives you a Docker image in which =E2=80=98guix-daemon=E2=80=99 is run=
ning, and
thus you can do =E2=80=9Cdocker run guix build=E2=80=9D (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=E2=80=99ve used Guix on top of a =E2=80=9Cfo=
reign distro=E2=80=9D
for CI, and I think it=E2=80=99s pretty useful in that context!
