UDP ports are not exposed correcty

[SebPikPik]

Hi,

I cloned this repo, modified the server infos (like users, passwords, server title) and tried to boot it up (which it does) but it seems that some ports are not exposed correctly using the docker compose file provided

f0beb9122b27 dedicated "./start.sh" 15 minutes ago Up 4 seconds 0.0.0.0:2350->2350/tcp, 0.0.0.0:5000->5000/tcp, 0.0.0.0:32807->2350/udp, 0.0.0.0:32789->3450/tcp, 0.0.0.0:32806->3450/udp maniaplanet-docker_dedicated_1

The ports 2350/udp, 3450/tcp and 3450/udp are randomly opened on my host (running docker 18.03)

A quick netstat from my docker host shows this :

tcp        0      0 :::2375                 :::*                    LISTEN      8934/dockerd

tcp        0      0 :::32789                :::*                    LISTEN      21460/docker-proxy
udp        0      0 :::32806                :::*                                21473/docker-proxy
udp        0      0 :::32807                :::*                                21495/docker-proxy

A netstat inside the container gives me this :

Ports in config files are the default ones

I took the compose file used on the repo project. Any idea ?

Found the issue

"expose" and "ports" were conflicting. Only using "ports" solved it

I'm having the same issue, When I want to connect to the server, I got an UDP initialization failed
the expose that you are talking about is the one in docker-compose ????

@Evilcious The expose and ports, is it only on your local docker-compose or in the repo? If in the repo, please tell me asap so we can fix it.

I resolved this issue btw, I just edit the docker-compose from that :

 dedicated:\
    image: pyplanet/maniaplanet-dedicated
    restart: always
    env_file: ./dedicated_vars.env
    volumes:
      - ./UserData:/dedicated/UserData
      - ./Logs:/dedicated/Logs
    expose:
      - "2350"
      - "2350/udp"
      - "3450"
      - "3450/udp"
      - "5000"
    ports:
      - 5000:5000
      - 2350:2350
      - "2350/udp"
      - "3450"
      - "3450/udp"

to that :

dedicated:
    image: pyplanet/maniaplanet-dedicated
    restart: always
    env_file: ./dedicated_vars.env
    volumes:
      - ./UserData:/dedicated/UserData
      - ./Logs:/dedicated/Logs
    ports:
      - 5000:5000
      - 2350:2350
      - "2350:2350/udp"
      - "3450:3450"
      - "3450:3450/udp"

without the :XXXX ,docker assigned a random port to 2350 and 3450 like you can see in @Evilcious 's screenshot

tcp        0      0 :::32789                :::*                    LISTEN      21460/docker-proxy
udp        0      0 :::32806                :::*                                21473/docker-proxy
udp        0      0 :::32807                :::*                                21495/docker-proxy
