at work we are using gitlab CI to build guix docker containers and run a
node on openshift for the bordeaux build farm:
   https://gitlab.inria.fr/enge/plm-guix
The README.md is completely outdated and serves mainly as a reminder to
myself on how this docker thing works; every time I look at it after a
break of a few months I have forgotten how to use a docker container...

And of course I have already forgotten the details; probably we should
write a little blog post. I will talk about it with my colleague when I
meet him next year ;-)

We also start with a Debian image and use a Dockerfile to install Guix
in it, as described in the Guix manual. Then for CI, we use this fixed
docker image to create a new one every time our repository (with a
channels.scm file and the plmshift.scm OS configuration file) changes.
In our case, this second docker image is the artefact that we then deploy.
We use "docker in docker" to create the images, and if I understood
correctly, this requires some privileges; these may not be given on
gitlab.com, but are available in our self-hosted instance.
