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.

Container Env Variables

Auto Update

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

Auto Backup

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

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

• /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.

Webhook Support

This repo can automatically send notifications to discord via the WEBHOOK_URL variable. Only use the documentation link below if you want advanced settings!
