Docker image for running Unturned Dedicated Server on Raspberry Pi 5

Set the password for the root user using this command:

sudo passwd root

Then enable remote connections to root user, open sshd_config file

sudo nano /etc/ssh/sshd_config

and add the following line to the file, after Include /etc/ssh/sshd_config.d/*.conf line

PermitRootLogin yes

Then restart the ssh service

sudo systemctl restart ssh

Now you can log in as root.

SteamCMD requires a kernel page size of 4KB.
To check the current page size run the following command

getconf PAGESIZE

If the page size is not 4KB (4096), but for example 16KB, you will need to change it by editing the boot configuration file

nano /boot/firmware/config.txt

Add the following line to the file

kernel=kernel8.img

Then reboot the device

reboot

Login as root user and run the following command to install Docker

curl -sSL https://get.docker.com/ | CHANNEL=stable bash

Then enable and start the Docker service

systemctl enable --now docker

Download Box64 repository

wget https://ryanfortner.github.io/box64-debs/box64.list -O /etc/apt/sources.list.d/box64.list

Add Box64 repository

wget -qO- https://ryanfortner.github.io/box64-debs/KEY.gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/box64-debs-archive-keyring.gpg

Update packages

apt update

Install Box64

apt install box64

First pull the latest version of the image

docker pull ghcr.io/restoremonarchyplugins/rpi5-unturned-server:latest

Then run the following command to create and start the server. This will create a new container named unturned and create a volume named U3DS in the current directory. The port 27115 is used for Rocket RCON. To join the server you will need to use Server Code.

docker run -d \
 --name unturned \
 -p 27115:27115 \
 -v ./U3DS:/opt/U3DS \
 ghcr.io/restoremonarchyplugins/rpi5-unturned-server:latest

• The server will automatically update on restart if there is a new version available
• To validate the server files, create .validate in U3DS folder. touch U3DS/.validate
• To disable RocketMod, create .vanilla in U3DS folder. touch U3DS/.vanilla
