-| `APP_HOSTNAME_ALIASES_RULE` | Traefik matcher listing additional hostnames that should permanently 301-redirect to `APP_HOSTNAME`. Each listed hostname also receives its own Let's Encrypt certificate so HTTPS bookmarks redirect cleanly. Leave unset on environments without aliases. | `` Host(`apollon-prod.aet.cit.tum.de`, `apollon.ase.cit.tum.de`, `apollon.ase.in.tum.de`) `` |
