Traefik v2 chooses wrong port

Traefik Traefik v2
1

I try to set a container that exposes two ports. I set

   labels:
       - traefik.enable=true
       - traefik.port=3000
       - traefik.docker.network=web
...
...

The services exposes two ports

        "NetworkSettings": {                                                                                                      
            "Bridge": "",                                                                                                         
            "SandboxID": "9c631f5aa1af0eb04befa34eb72fc71fe92e2122285465c94bdd552337be26bf",                                      
            "HairpinMode": false,                                                                                                 
            "LinkLocalIPv6Address": "",                                                                                           
            "LinkLocalIPv6PrefixLen": 0,                                                                                          
            "Ports": {                                                                                                            
                "22/tcp": null,                                                                                                   
                "3000/tcp": null                                                                                                  
            },     
...
...

And traefik keeps assigning port number 22 to the service:
29-09-2019-18%3A34-scrot

What could be wrong?

It seems like traefik.port label inside a container definition doesn't work at all for some reason.

The correct setting must be

traefik.http.services.service_name.loadbalancer.server.port=42"

Some reason would be that you are trying to use v1 syntax with v2. This is not supported.
