Valheim

Valheim is a viking-themed survival game.

Introduction

This chart creates a single Valheim headless pod, using the lloesche/valheim-server Docker image.

Note: the image will automatically update the server as well as backup the data on a regular basis, see values.yml or the details of the image itself for further configuration details.

Prerequisites

• Kubernetes 1.4+ with Beta APIs enabled
• PV provisioner support in the underlying infrastructure

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release .

This command deploys a Valheim dedicated server with sane defaults.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

Refer to values.yaml for the full run-down on defaults.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release --set var1=Value1,var2=Value2 .

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

$ helm install --name my-release -f values.yaml .

Tip: You can use the default values.yaml

Persistence

The valheim-server image stores persistent data under /config attached to the persistent volume.

Access to the Server

By default, the chart will create the service as a LoadBalancer with UDP port mappings (2456, 2457 and 2458 by default).

However in some instances, providers will not allow UDP mapping on load balancers, so the chart can be configured to use NodePort. In this case, it is also recommended to use ports within the default node port range. For example: --set valheimServer.serviceType=NodePort,valheimServer.serverPort=32456.

Instructions on how to retrieve the IP/port of the server will be displayed after running the helm install.

Note: valheimServer.serverPort (default 2456) only indicates the first of the three ports defined by the server. The server will automatically open three consecutives ports over UDP, i.e. with the default value of 2456, this would be: 2456, 2457 and 2458.

Steam Configuration

Go to view > servers > add a server and then add this address to favorites.

The port to be used here should be the second one of the three, i.e. with the default value 2456, the port to connect to in Steam should be 2457.

Note: For reasons that aren't yet competely clear to me, this can be a bit finicky. First, make sure the server is correctly added in Steam. Then start the game > join game, select friends, then back in Steam, connect to the server, then back in the game again it should automatically connect and you should be able to press start and get going.

Example Setup

cd valheim-server-helm
kubectl create namespace valheim
helm upgrade --install valheim-server --set valheimServer.serverName="My Valheim Server",valheimServer.worldName="My Valheim World",valheimServer.serverPass="password",valheimServer.serverPublic=0,valheimServer.serviceType=NodePort,valheimServer.serverPort=32456 --namespace valheim .

This will setup the Valheim server within the valheim-server namespace, make it private and accessible through the node's IP and port (32456).
