zot24/valheim-docker repository overview

⁠Valheim⁠

⁠

⁠Docker

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
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.
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	`12345`	TRUE	Set this to something unique!
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_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_REMOVE_OLD	`1`	FALSE	Set to `0` to keep all backups or manually manage them.

AUTO_BACKUP_ON_SHUTDOWN	`0`	FALSE	Create a backup on shutdown.

⁠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

This repo automatically launches with the proper environment variables for BepInEx. However, you have to install it manually in the container due to the fact that the modding community around Valheim is still in its infancy.

Click Here to view documentation on BepInEx Support⁠

⁠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!
