Multiple ports on the same service

Traefik Traefik v3 (latest)

I'm attempting to setup a calibre route and service for both the webpage and the opds server. I'm... strugglilng to get this to work, despite looking through other examples throughout the forums.

Starting this up results in it creating two services for both calibre and calibreopds, but not two route. Any thoughts on this?

When using multiple services on labels, you need to make sure to use the correct router names and assign each a service:

      - traefik.http.routers.calibre.rule=Host(`calibre.internal.domain.com`)
      - traefik.http.routers.calibre.service=calibre
        #                    ^^^
      - traefik.http.services.calibre.loadbalancer.server.port=8080

      - traefik.http.routers.calibreopds.rule=Host(`calibreopds.internal.domain.com`)
      - traefik.http.routers.calibreopds.service=calibreopds
        #                    ^^^
      - traefik.http.services.calibreopds.loadbalancer.server.port=6838

Also, you're using a reverse proxy, so don't publish the ports. It just gets confusing (and potentially prevents the container from starting).

Btw, the calibreopds service should have specified port 8081. Like I said... it gets confusing
