cs2s

This repository serves as a CS2 server mod development environment. It provides a Dockerfile and setup script for managing an Ubuntu container with SteamCMD and CS2 preinstalled.

Setup

In order to use cs2s you will need the following.

1. Docker
2. Any Steam account credentials

To get started, build the included Docker image. This creates an Ubuntu 20.04 LTS with a whole host of packages including:

• Developer tools
• CS2 dependencies
• Metamod dependencies
• SteamCMD

You can spin up a container from this image by running:

docker compose up --detach  # or -d

# Open a TTY (bash is installed if you prefer)
docker compose exec cs2s zsh

Use

Once you've started your container, you'll want to install CS2. It'll be installed in a persistent volume that can be reused across containers:

# Run the installation script
cs2s-install

You can then use cs2s-overlay to create and run overlays of your CS2 installation. This allows you to simulate having multiple independently-writable copies of the game via OverlayFS.

# Create /home/steam/my-overlay
cs2s-overlay add my-overlay

# Editing files only affects the overlay
touch /home/steam/my-overlay/game/csgo/cfg/autoexec.cfg

# Confirm by checking the original installation
ls /cs2/game/csgo/cfg/

# You can see changes in the mounted "upper" directory
ls /home/steam/.overlay/test/upper/game/csgo/cfg

# To run the server in the overlay, you can either `su steam` etc. or use the shorthand
cs2s-overlay start my-overlay +de_dust2
