Valheim Docker Server

Starts a Valheim dedicated server inside of a docker container. The server will be available on <server_ip>:2457 The game and server is still in early access and so I'll update this container as more information on the server is released.

Sometimes the server can take a while to show up in the community server list in game. If you can't find then try the following:

In Steam go to view > servers
Click the "Add A Server" button in the bottom right
Type in the server Ip and selected port. <server_ip>:2457
Click "Add this address to favorites"
Hit the "Refresh" button and your server should be displayed in the list

It can take a few minutes for the server to be available while it downloads the server files and configures itself.

Env Vars

You can configure some basic server options using the below ENV vars

Variable	Description
SERVER_NAME	Sets the name of the server. Default: My server
SERVER_PASSWORD	Sets the server password. Default: password123
SERVER_WORLD	Sets the required world ID. Default: Dedicated

Starting the server

Replace <HOST_STORAGE_DATA_LOCATION> and <HOST_STORAGE_CONFIG_LOCATION> with the paths on your docker host where you would like to persist the container data.

Docker

docker run --name Valheim -d \
	-p 2456-2458:2456-2458/udp \
	--env 'SERVER_NAME=My Valheim Server' \
	--env 'SERVER_PASSWORD=password123' \
	--volume <HOST_STORAGE_DATA_LOCATION>:/root/valheim/data:rw \
	--volume <HOST_STORAGE_CONFIG_LOCATION>:/root/.config/unity3d/IronGate/Valheim:rw \
	taggr/docker-valheim-server:latest

Docker Compose

version: '3'

services:
  valheim-server:
    image: taggr/docker-valheim-server:latest
    ports:
      - "2456-2458:2456-2458/udp"
    volumes:
      - "<HOST_STORAGE_DATA_LOCATION>:/root/valheim/data:rw"
      - "<HOST_STORAGE_CONFIG_LOCATION>:/root/.config/unity3d/IronGate/Valheim:rw"
    network_mode: "bridge"
    restart: unless-stopped
    environment:

      - SERVER_PASSWORD=password123

Copy the above into a docker-compose.yml file and you can start the server by running docker-compose up valheim-server or to start the server in the background docker-compose up -d valheim-server

Server Data Persistance

The server data will be persisted in the chosen paths on the host set by <HOST_STORAGE_DATA_LOCATION> and <HOST_STORAGE_CONFIG_LOCATION> when starting the container.
