Stardew Valley Multiplayer Docker Compose

This project aims to autostart a Stardew Valley Multiplayer Server as easy as possible.

Side Note

• Updating to most recent version requires a rebuild: docker-compose build --no-cache
• Although I'm trying to put out updates, I don't have the time for testing, so I recommend forking and fixing things on your own.

Setup

Docker-Compose

git clone https://github.com/printfuck/stardew-multiplayer-docker

docker-compose up

Ansible

Create an inventory file with your hosts

ansible -i <your_inventori> playbook.yml

Terraform (with Hetzner Cloud)

Enter your API Token in terraform/vars.auto.tfvars and modify the resource section in main.tf to your liking, then run the following script:

./terra.sh

Game Setup

Intially you have to create or load a game once at first startup via VNC. After that the Autoload Mod jumps into the previously loaded savegame everytime you rerun the container. You can also edit the config file of the Autoload Mod to archieve similar behaviour.

VNC

Use a vnc client like TightVNC on Windows or plain vncviewer on any Linux distribution to connect to the server. You can modify the VNC Port and IP address and Password in the docker-compose.yml file like this:

Localhost:

   # Server is only reachable on localhost on port 2342...
   ports:
     - 127.0.0.1:2342:5900
   # ... with the password "insecure"
   environment:
     - VNCPASS=insecure

How it works

The game, the modloader (SMAPI), and the necessary Mods are pulled from my servers (I'll assume you already own the game - since you're looking for a multiplayer - so please don't rip it from there) to minimize version conflicts. The docker-entrypoint.sh script will start Xvfb and x11vnc before starting the game. You can control the game via vnc with the settings within the docker-compose.yml file.

Used Mods

• AutoLoadGame
• Always On
• Unlimited Players

Troubleshooting

Error Messages in Console

Usually you should be able to ignore any message there. If the game doesn't start or any errors appear, you should look for messages like "cannot open display", which would most likely indicate permission errors.

VNC

Access the game via VNC to initially load or start a pregenerated savegame. You can control the Server from there or edit the config.json files in the configs folder.

Performance

I'd recomend a VPS/Machine with at least four logical CPUs and 4GB Ram, otherwise there will be horrible lags. The minimum configuration I'd consider playable with two to four players would be two logical CPUs and 1GB of Ram.
