Survive the Nights server

Run a Survive the Nights dedicated server with LinuxGSM, in Docker or directly on Linux.

stnserver Docker stnUnity 3D

Run with Docker

First install Docker Engine and the Compose plugin on your Linux host. Run the commands below from your project directory with a user allowed to access Docker; otherwise prefix Docker commands with sudo. The container manages its own linuxgsm user.

The stn image has LinuxGSM and every dependency for Survive the Nights already installed on Ubuntu 26.04. On first start it downloads the game server, then keeps it updated.

1. Create `compose.yaml`

compose.yaml

services:
  stnserver:
    image: ghcr.io/gameservermanagers/gameserver:stn
    container_name: stnserver
    restart: unless-stopped
    network_mode: host
    volumes:
      - ./stnserver:/data
    environment:
      - UPDATE_CHECK=60

Also published on Docker Hub as gameservermanagers/gameserver:stn. Prefer docker run? See Docker help.

2. Start it

shell

docker compose up -d
docker compose logs -f

The first start installs the server, which can take a while for large games. When it is ready the log shows the server details, including ports and passwords.

Ports

With network_mode: host the server uses the host's ports directly, so there is nothing to map. Open them in your firewall.

Ports for this game are set in its own config file. Run details to see every port and its protocol.

Manage the server

Show details, ports and passwords

docker exec -it --user linuxgsm stnserver ./stnserver details

Open the live console (leave with CTRL+b then d)

docker exec -it --user linuxgsm stnserver ./stnserver console

Restart the game server

docker restart stnserver

Check for a game update now

docker exec -it --user linuxgsm stnserver ./stnserver update

Update the image

docker compose pull && docker compose up -d

Server files, configs and logs live in ./stnserver on the host: back up that directory. Docker help below covers permissions, environment variables and bridge networking.

Images and tags

Images are built weekly and published to two registries. They are identical, so use whichever you prefer.

Registry	Image
GitHub Container Registry	`ghcr.io/gameservermanagers/gameserver:stn`
Docker Hub	`gameservermanagers/gameserver:stn`

The image uses the base OS LinuxGSM recommends for this game. You do not need to match it on the host.

Use docker run instead of Compose

shell

docker run -d \
  --name stnserver \
  --network host \
  --restart unless-stopped \
  -v "$PWD/stnserver:/data" \
  -e UPDATE_CHECK=60 \
  ghcr.io/gameservermanagers/gameserver:stn

Data and permissions

Everything that should survive a container update lives in /data inside the container, which is ./stnserver on the host.

Path in `/data`	Contents
`serverfiles/`	The game server itself
`config-lgsm/`	LinuxGSM config, including `common.cfg`
`log/`	Script, console and game logs
`data/`	LinuxGSM data and cache

The game server runs as the linuxgsm user, not root. On every start the container sets that user to UID and GID (both 1000 by default) and takes ownership of /data. If your host user has a different ID, set them to match so you can edit files on the host:

compose.yaml

environment:
      - UID=1001
      - GID=1001

Environment variables

Variable	Default	What it does
`UPDATE_CHECK`	`60`	Minutes between update checks, from `1` to `59`, or `60` for hourly. `0` turns scheduled checks off.
`UPDATE_ON_START`	`true`	Check for a game update every time the container starts.
`VALIDATE_ON_START`	`false`	Run a SteamCMD validate on start. Slow, but repairs broken files.
`UID` / `GID`	`1000`	User and group IDs the game server runs as.
`LGSM_GITHUBBRANCH`	`master`	LinuxGSM branch to run. Set `develop` to test unreleased fixes.

Updates and health checks

The game server updates itself. The container checks every UPDATE_CHECK minutes and on start. If an update is out, it stops the server, updates it and starts it again.

The image brings new LinuxGSM releases, dependency fixes and OS updates. Pull it now and then with docker compose pull && docker compose up -d.

The image runs LinuxGSM's monitor as the Docker health check every minute, so docker ps shows whether the game server is answering, not just whether the container is up.

Bridge networking

network_mode: host is the simplest choice: the game server uses the host's ports directly, the way it would without Docker, and query ports work without extra setup.

If you need bridge networking, publish each port the server uses. Run details to see them, then add them with the right protocol:

compose.yaml

ports:
      - "PORT:PORT/udp"
      - "PORT:PORT/tcp"

Bridge networking can hide the server's real IP from the game, which breaks some server browsers. Use host networking if players cannot find the server.

Troubleshooting

Permission denied in /data: set UID and GID to the owner of the host directory.
Server not listed in game: check the ports are open, use host networking, and add a GSLT if the game needs one.
Install fails at SteamCMD: the game may need a Steam login. Check the notes at the top of this page.
Will not start: stop the container, then run docker compose run --rm stnserver debug to see why.
Still stuck: run details and debug, then ask on Discord or GitHub Discussions with the output.

Install on Linux

Install directly on a server running Ubuntu 26.04, Debian 11 or Enterprise Linux 8.

1. Create a user and log in

Creating users and installing system packages require administrator privileges. From your administrator account, use sudo below (omit it if already root). Install curl, tar and an editor such as nano with your distribution's package manager first.

administrator shell

sudo adduser stnserver

Give the user a strong password, then switch to its login shell:

administrator shell

sudo su - stnserver

Run all remaining commands as stnserver from its home directory, without sudo. On Enterprise Linux, create the account with sudo useradd -m stnserver and set its password with sudo passwd stnserver instead of adduser.

2. Download LinuxGSM

shell

curl -Lo linuxgsm.sh https://linuxgsm.sh && chmod +x linuxgsm.sh && bash linuxgsm.sh stnserver

3. Install

shell

./stnserver install

LinuxGSM checks dependencies and installs the game files. If this user has sudo access, it can install missing packages when prompted. Otherwise, ask an administrator to install the packages listed by LinuxGSM, then rerun this command as stnserver. Running ./stnserver install as root only installs dependencies, not the game server.

4. Configure and start the server

Review your LinuxGSM settings in lgsm/config-lgsm/stnserver/stnserver.cfg (instance settings) or lgsm/config-lgsm/stnserver/common.cfg (shared settings). Do not edit _default.cfg, which LinuxGSM updates automatically. Game settings use a separate config file; run ./stnserver details to find its path. Once configured, start the server explicitly:

shell

./stnserver start

Common commands

Start the server

start

./stnserver start

Stop the server

stop

./stnserver stop

Restart the server

restart

./stnserver restart

Show details, ports and passwords

./stnserver details

Open the live console (leave with CTRL+b then d; CTRL+c stops the server)

./stnserver console

Update the game server

./stnserver update

Run in the foreground to debug

./stnserver debug

Back up the whole server

./stnserver backup

List every command

./stnserver

Automate with cron

Restart the server if it crashes, apply game updates and keep LinuxGSM current. Add these with crontab -e.

crontab

*/5 * * * * /home/stnserver/stnserver monitor > /dev/null 2>&1
*/30 * * * * /home/stnserver/stnserver update > /dev/null 2>&1
0 0 * * 0 /home/stnserver/stnserver update-lgsm > /dev/null 2>&1
