I was able to get Gitlab CICD to build the HPR static site.

First step was creating a mirror of the HPR generator repo:

git clone gitea@repo.anhonesthost.net:rho_n/hpr_generator.git
git remote add gitlab_mirror git@gitlab.com:norrist/hpr_generator_mirror.git
git push gitlab_mirror  main

Then I created a Gitlab CICD pipeline to:
- check out the hpr site generator from the mirror
- load the HPR daily mysql dump into a mysql database
- build the site
- publish to gitlab pages.

The CI project is https://gitlab.com/norrist/hpr_generator_build

The build is published at https://norrist.gitlab.io/hpr_generator_build/
