You can add custom labels for every room.
Example: Expose port 3000 from every room under 3000-(room-name):
-e "NEKO_ROOMS_INSTANCE_LABELS=
traefik.http.services.{containerName}-3000-tcp.loadbalancer.server.port=3000
traefik.http.routers.{containerName}-3000-tcp.entrypoints={traefikEntrypoint}
traefik.http.routers.{containerName}-3000-tcp.rule=PathPrefix(\`/3000-{roomName}\`)
traefik.http.middlewares.{containerName}-3000-tcp-prf.stripprefix.prefixes=/3000-{roomName}/
traefik.http.routers.{containerName}-3000-tcp.middlewares={containerName}-3000-tcp-prf
traefik.http.routers.{containerName}-3000-tcp.service={containerName}-3000-tcp
