How To Transfer Files

For this tutorial, we will be using schollz/croc which is a cli tool for sending files. This is for temporary access to transfer files and if you want to do this frequently, then consider running a file browser sidecar container.

Setup

1. Access the container via the root user.

# This can be accomplished via many methods but for this tutorial we will be using docker-compose.
docker-compose exec valheim bash

# 1. Replace valheim with the name of your container.
# 2. This tutorial cannot account fo all the wide variety of names or methods on which the container is created.
# 3. You just need to access the container via the root user to install croc.

1. Run curl https://getcroc.schollz.com | bash inside the mbround18/valheim container.
2. Run curl https://getcroc.schollz.com | bash inside the destination machine. (If the destination machine is not a linux|unix based system with access to bash, please look at schollz/croc repo for installation instructions.)

Instructions

For this example, we will be transfering world files from one instance of mbround18/valheim to another mbround18/valheim. If you have a slightly different use case, such as transfering backups or something else, then this guide will be helpful but not match 1 to 1.

1. Access the mbround18/valheim container A and container B as the steam user.

   # This can be accomplished via many methods but for this tutorial we will be using docker-compose.
   docker-compose exec --user steam valheim bash
   
   # Replace valheim with the name of your container.
   # This tutorial cannot account fo all the wide variety of names or methods on which the container is created.
   # You just need to access the container via the steam user when sending the files.
   

2. Stop the valheim server on both machines, odin stop

3. Cd into your saves dir with cd /home/steam/.config/unity3d/IronGate/Valheim on both container A and container B.

4. With croc already installed, run croc send ./* on container A.

   

5. Once it spits out the transfer key, copy the transfer key to container B and hit the enter key.

   

6. You can now safely shutdown container A and restart container B.
