Traefik with lots of routes in one docker service

Traefik Traefik v2
1

Hello traefik community,

I'm getting the following error when I use my attached docker-compose file.

time="2021-01-10T14:28:28Z" level=error msg="Could not define the service name for the router: too many services" providerName=docker routerName=emqx-http

When I remove for example the websocket config than the redirect from http to https is working. If everything is defined traefik remove http or like I assume the oldest defined route.

emqx2 needs a service, it has too many (>1) to choose from, you could use noop@internal for this.

Otherwise if you are only planning on using https then you can use entrypoint redirection instead.

What do you mean with service?

I add the service line like this.

      - "traefik.enable=true"
      - "traefik.http.routers.emqx-http.rule=Host(`emqx.<host>`)"
      - "traefik.http.routers.emqx-http.entrypoints=http"
      - "traefik.http.routers.emqx-http.middlewares=redirect-emqx"
      - "traefik.http.middlewares.redirect-emqx.redirectscheme.scheme=https"
      - "traefik.http.routers.emqx-http.service=emqx"
