The customization of the Gitlab home page is a proprietary extension that is not available in the Free Software version. When running Gitlab from docker containers, the home page template needs to be moved to a file that won’t go away with the container:
$ layouts=/home/git/gitlab/app/views/layouts/ $ docker exec gitlab mkdir -p /home/git/data/$layouts $ docker exec gitlab mv $layouts/devise.html.haml /home/git/data/$layouts $ docker exec gitlab ln -s /home/git/data/$layouts/devise.html.haml \ $layouts/devise.html.haml
The template can now be modifed in /opt/gitlab/data/home/git/gitlab/app/views/layouts/ from the host running the container. It is a HAML template which can have raw HTML as long as proper indentation is respected.
