⁠Valheim Dedicated Server - Docker Image and Helm Chart

This Docker image provides a Valheim⁠ dedicated game server. You will also find a Helm chart⁠ here for running a Valheim dedicated server on Kubernetes container orchestration system⁠.

My automation checks the Valheim public branch⁠ every night. If a new release was published by Iron Gate Studios⁠, a new Docker image will be built with this new version. Just use the latest tag and you will always have an up-to-date Docker image. No need to manually run any server updates and mess around with your Docker image. It's that simple. :smiley:

Have a look at the docker compose example⁠ and its documentation⁠. There you can see how a server update can be automated with a simple script. You can also read my blog article for setting up your own Valheim server with Docker and Docker Compose⁠ for getting some further instructions.

Kudos to:

• @jonakoudijs⁠ for providing the Steamcmd Docker image⁠ which is used here

⁠Usage

⁠Configuration

You can append all Valheim console commands⁠ as arguments when running the valheim_server.x86_64 binary. Use the regular syntax like -name ValheimServer or -public 1.

As the Valheim server is running in the Docker container as a stateless application, you want to have all stateful server data (config, saves, etc.) stored in a Docker volume⁠ which is persisted outside the container. This can be configured with -savedir: you can specify the directory where this data is stored. You need to make sure that this directory is mounted on a Docker Volume⁠.

This is especially important because you need to update the Valheim server image every month when Iron Gate Studios⁠ releases a new software update. When you use a Docker volume⁠ to store the -savedir, all the data is still intact.

⁠Docker Run

For testing purposes, you can fire up a Docker container like this:

docker run -it --publish 2456:2456/udp --publish 2457:2457/udp pfeiffermax/valheim-dedicated-server:latest -name ValheimServer -world NewWorld -password supersecret -public 0

⁠Docker Compose

Please have a look at the docker compose example⁠.

⁠Podman Compose on a remote builder

The image is built with Podman⁠. If you want to build and run it yourself on a remote linux/amd64 Podman host — handy on an arm64 machine, where the 32-bit x86 steamcmd binary used in the image build cannot be emulated — have a look at the podman compose remote builder example⁠.

⁠Helm chart

If you would like to run the Valheim server in your Kubernetes⁠ cluster, I provide a Helm chart⁠ you could use: https://max-pfeiffer.github.io/valheim-dedicated-server-docker-helm⁠

There is also documentation available⁠ for that Helm chart.

If you want to run your Valheim server on bare metal Kubernetes, check out my blog article⁠ on how to do that using Cilium⁠.
