Hi Ludo

I normally do the following and it seems to work fine with our gitlab
instance:

registry=registry.gitlab.ost.ch:45023/sciceg/teaching/eeu_mlds
archive=$(guix time-machine -C channels.scm -- pack -f docker -S /bin=bin -S 
/lib=lib -S /share=share -m manifest.scm)
tag=$(docker load -i $archive)
docker tag ${tag##*"Loaded image: "} $registry
docker push $registry

what seems to be crucial is to add the following packages to the
manifest file:

"bash" 
"coreutils"
"git"

than I can use the image in the gitlab-ci.yml file

generate-exercises:
  image: registry.gitlab.ost.ch:45023/sciceg/teaching/eeu_mlds:latest
  ...

Hope that helps!

Best,
Reza

PS: It would be really nice if one could provide a docker tag directly
to `guix pack -f docker`
