Applied together this will allow you to provision extra JVB instances which will register themselves with the prosody service and be available for jicofo
to route conferences too.
To make Traefik reverse-proxy to these additional JVBs (living on other hosts), **you would need to add the following Traefik configuration extension**:
```yaml
# Traefik proxying for additional JVBs. These can't be configured using Docker
# labels, like the first JVB is, because they run on different hosts, so we add
# the necessary configuration to the file provider.
