What?

This is a Dockerfile allowing you to run the Conan Exiles Dedicated Server inside of a Docker container, through Wine.

How to use this image

The image includes a Makefile that can be used to build it by just typing Make

To create a container from the image, assuming the default image name set by the Makefile:

$ docker create \
    --name conan \
    -p7777:7777/udp \ 
    -p7778:7778/udp \
    -p27015:27015/udp \ 
    -e PUID=1000 \
    -e PGID=1000 \
    -v /mnt/docker/conan:/home/steam/conan-dedicated \
    bgeens/conan-exiles-server:0.1

or using Docker Compose:

version: "3.2"

services:
  conan:
    image: bgeens/conan-exiles-server:0.1
    container_name: conan
    restart: "unless-stopped"
    volumes:
      - /mnt/docker/conan:/home/steam/conan-dedicated
    environment:
      - PUID=1000
      - PGID=1000
    ports:
      - 7777:7777/udp
      - 7778:7778/udp
      - 27015:27015/udp

Exposed ports

Port	Protocol	Function
7777	UDP	game port (direct connections)
7778	UDP	game port (connections through Steam)
27015	UDP	Steam server browser port

Exposed variables

To map the internally used group and user to ones existing on the host machine:

• PUID : the user ID for use by the server process
• PGID : the group ID for use by the server process
• CONAN_ARGS : arguments passed to the Conan server process, defaults to -log -nosteam.

Not setting these is likely to lead to all kinds of permission errors.

Mods

The container will create a modlist.txt file in the root of the Docker volume on first startup if it does not already exist.

The contents of the file looks something like this:

880177231       # Pythagoras
1472647650      # Limestone Buildings
1369802940      # Emberlight
1159180273      # Fashionist
1491981725      # LBPR

Make sure the second column (with the comments) is separated from the first with a tab (processing is done with awk, so anything awk considers a valid column separator should work). The second column is only there for human readability, listing only the mods numbers works just fine as well (but might be a tad harder to maintain)

Known issues

• The created container does not show up in the Steam or ingame server browsers for me. Direct connections through IP do work though (but I have to type in the address twice, once to connect and again after it fails to automatically connect after a the restart to activate appropriate mods)

  This might be something on my end, or related to some issue in the server software itself. Scanning for the server from Steam always leads to one of these showing up in the dedicated server logs:

  PacketHandlerLog:Error: PacketHandler parsing packet with zero's in last byte.
  002c:err:eventlog:ReportEventW L"PacketHandler parsing packet with zero's in last byte."
  
  

  This is over a LAN from a different machine, so no firewall or port conflicts should be involved.
