Can't get to the URL (Gitlab appears down?), however does this support, or preferably incorporate, a reverse proxy like HAProxy or Nginx to handle SSL (auto/LE preferably) and domain/ACL based back-ends?(eg, instead of having a bunch of different front-end ports with a single-domain entry-point)
How often do the GitLab trending repositories update? HomelabOS has doubled from 130 to 260 stars in under a day, but the 'Trending' page mostly shows a bunch of repos with 10-30 stars.
That's a really interesting question. However, I think that's not something regular, so there's no fixed multiplication. It may double or multiply even more, there's no rule :-).
