Running on a bare-metal Linux Server

From Release

1. Navigate to https://github.com/mbround18/valheim-docker/releases/latest
2. Download the bundle.zip to your server
3. Extract the bundle.zip
4. Make the files executable chmod +x {odin,huginn}
5. Optional: Add the files to your path.
6. Navigate to the folder where you want your server installed.
7. Run odin configure --password "Your Super Strong Password" (you can also supply --name "Server Name", --port "Server Port", or other arguments available.)
8. Finally, run odin start.

From Source

This repo bundles its tools in a way that you can run them without having to install docker! If you purely want to run this on a Linux based system, without docker, take a look at the links below <3

• Installing & Using Odin The tool Odin runs the show and does almost all the heavy lifting in this repo. It starts, stops, and manages your Valheim server instance.
• Installing & Using Huginn Looking for a way to view the status of your server? Look no further than Huginn! The Huginn project is a http server built on the same source as Odin and uses these capabilities to expose a few http endpoints.

Using the binaries to run on an Ubuntu Server, you will have to be more involved and configure a few things manually. If you want a managed, easy one-two punch to manage your server. Then look at the Docker section <3

Running with Docker

This image does use verion 3+ for all of its compose examples. Please use Docker engine >=20 or make adjustments accordingly.

If you are looking for a guide on how to get started click here

Mod Support! It is supported to launch the server with BepInEx but!!!!! as a disclaimer! You take responsibility for debugging why your server won't start. Modding is not supported by the Valheim developers officially yet; Which means you WILL run into errors. This repo has been tested with running ValheimPlus as a test mod and does not have any issues. See Getting started with mods

Environment Variables

See further on down for advanced environment variables.

Variable	Default	Required	Description
PORT	2456	TRUE	Sets the port your server will listen on. Take note it will also listen on +2 (ex: 2456, 2457, 2458)
NAME	Valheim Docker	TRUE	The name of your server! Make it fun and unique!
WORLD	Dedicated	TRUE	This is used to generate the name of your world.
PUBLIC	1	FALSE	Sets whether or not your server is public on the server list.
PASSWORD	<please set me>	TRUE	Set this to something unique!
ENABLE_CROSSPLAY	0	FALSE	Enable crossplay support as of Valheim Version >0.211.8
TYPE	Vanilla	FALSE	This can be set to ValheimPlus, BepInEx, BepInExFull or Vanilla
PRESET	``	FALSE	Normal, Casual, Easy, Hard, Hardcore, Immersive, Hammer
MODIFIERS	``	FALSE	Comma-separated array of modifiers. EX: combat=easy,raids=muchmore
SET_KEY	``	FALSE	Can be one of the following: nobuildcost, playerevents, passivemobs, nomap
MODS	<nothing>	FALSE	This is an array of mods separated by comma and a new line. Click Here for Examples Supported files are zip, dll, and cfg.
WEBHOOK_URL	<nothing>	FALSE	Supply this to get information regarding your server's status in a webhook or Discord notification! Click here to learn how to get a webhook url for Discord
WEBHOOK_INCLUDE_PUBLIC_IP	0	FALSE	Optionally include your server's public IP in webhook notications, useful if not using a static IP address. NOTE: If your server is behind a NAT using PAT with more than one external IP address (very unlikely on a home network), this could be inaccurate if your NAT doesn't maintain your server to a single external IP.
UPDATE_ON_STARTUP	1	FALSE	Tries to update the server the container is started.
ADDITIONAL_STEAMCMD_ARGS	``	FALSE	Sets optional arguments for install

Container Env Variables

Variable	Default	Required	Description
TZ	America/Los_Angeles	FALSE	Sets what timezone your container is running on. This is used for timestamps and cron jobs. Click Here for which timezones are valid.
PUID	1000	FALSE	Sets the User Id of the steam user.
PGID	1000	FALSE	Sets the Group Id of the steam user.

Auto Update

Variable	Default	Required	Description
AUTO_UPDATE	0	FALSE	Set to 1 if you want your container to auto update! This means at the times indicated by AUTO_UPDATE_SCHEDULE it will check for server updates. If there is an update then the server will be shut down, updated, and brought back online if the server was running before.
AUTO_UPDATE_SCHEDULE	0 1 * * *	FALSE	This works in conjunction with AUTO_UPDATE and sets the schedule to which it will run an auto update. If you need help figuring out a cron schedule click here
AUTO_UPDATE_PAUSE_WITH_PLAYERS	0	FALSE	Does not process an update for the server if there are players online.

Auto update job, queries steam and compares it against your internal steam files for differential in version numbers.

Auto Backup

Variable	Default	Required	Description
AUTO_BACKUP	0	FALSE	Set to 1 to enable auto backups. Backups are stored under /home/steam/backups which means you will have to add a volume mount for this directory.
AUTO_BACKUP_SCHEDULE	*/15 * * * *	FALSE	Change to set how frequently you would like the server to backup. If you need help figuring out a cron schedule click here.
AUTO_BACKUP_NICE_LEVEL	NOT SET	FALSE	Do NOT set this variable unless you are following this guide here
AUTO_BACKUP_REMOVE_OLD	1	FALSE	Set to 0 to keep all backups or manually manage them.
AUTO_BACKUP_DAYS_TO_LIVE	3	FALSE	This is the number of days you would like to keep backups for. While backups are compressed and generally small it is best to change this number as needed.
AUTO_BACKUP_ON_UPDATE	0	FALSE	Create a backup on right before updating and starting your server.
AUTO_BACKUP_ON_SHUTDOWN	0	FALSE	Create a backup on shutdown.
AUTO_BACKUP_PAUSE_WITH_NO_PLAYERS	0	FALSE	Will skip creating a backup if there are no players. PUBLIC must be set to 1 for this to work!

Auto backup job produces an output of a *.tar.gz file which should average around 30mb for a world that has an average of 4 players consistently building on. You should be aware that if you place the server folder in your saves folder your backups could become astronomical in size. This is a common problem that others have observed, to avoid this please follow the guide for how volume mounts should be made in the docker-compose.yml.

Scheduled Restarts

Scheduled restarts allow th operator to trigger restarts on a cron job

Variable	Default	Required	Description
SCHEDULED_RESTART	0	FALSE	Allows you to enable scheduled restarts
SCHEDULED_RESTART_SCHEDULE	0 2 * * *	FALSE	Defaults to everyday at 2 am but can be configured with valid cron

Docker Compose

This image does use verion 3+ for all of its compose examples. Please use Docker engine >=20 or make adjustments accordingly.

Simple

This is a basic example of a docker compose, you can apply any of the variables above to the environment section below but be sure to follow each variables' description notes!

Bundled Tools

Odin

This repo has a CLI tool called Odin in it! It is used for managing the server inside the container. If you are looking for instructions for it click here: Odin

Click here to see advanced environment variables for Odin

Huginn Http Server

Variable	Default	Required	Description
ADDRESS	Your Public IP	FALSE	This setting is used in conjunction with odin status and setting this will stop odin from trying to fetch your public IP
HTTP_PORT	anything above 1024	FALSE	Setting this will spin up a little http server that provides two endpoints for you to call.

• /metrics provides a prometheous style metrics output.
• /status provides a more traditional status page.

Note on ADDRESS this can be set to 127.0.0.1:<your query port> or <your public ip>:<your query port> but does not have to be set. If it is set, it will prevent odin from reaching out to aws ip service from asking for your public IP address. Keep in mind, your query port is +1 of what you set in the PORT env variable for your valheim server.

Another note: your server MUST be public (eg. PUBLIC=1) in order for Odin+Huginn to collect and report statistics.

Feature Information

BepInEx Support

As of March 2021 the TYPE variable can be used to automatically install BepInEx. For details see Getting started with mods.
