This is the containerized service infrastructure for various miscellaneous, static, and old bits of the lojban.org infrastructure; it's the webserver that catches everything not caught by other subdomains.
This is an LBCS instance (see https:/lojban/lbcs/ ), which is why a bunch of things in here are symlinks off into apparently empty space; you have to have LBCS installed in /opt/lbcs/ for them to work.
That's also where the docs on how to like start and stop the service and so on are.
NOTE: The data structure is NOT like other LBCS instances, as all the containers mount data/ in the main directory. This also means that there's a special fcontext rule for this user:
sudo semanage fcontext -a -t container_file_t '/home/spdrata/misc-containers/data(/.*)?'
