# What is Counter-Strike 2?
For over two decades, Counter-Strike has offered an elite competitive experience, one shaped by millions of players from across the globe. And now the next chapter in the CS story is about to begin. This is Counter-Strike 2.
This Docker image contains the dedicated server of the game.
> [CS2](https://store.steampowered.com/app/730/CounterStrike_2/)
# How to use this image
## Hosting a simple game server
Running on the *host* interface (recommended) using Docker:
```console
$ docker run -d --name=cs2 -p 27015:27015 -p 27020:27020 joedwards32/cs2
```
Running using a bind mount for data persistence on container recreation:
```console
$ mkdir -p $(pwd)/cs2-data
$ chmod 777 $(pwd)/cs2-data # Makes sure the directory is writeable by the unprivileged container user
$ docker run -d --name=cs2 -v $(pwd)/cs2-data:/home/steam/cs2-dedicated/ -p 27015:27015 -p 27020:27020 joedwards32/cs2
```
or using docker-compose, see [examples](https://github.com/joedwards32/CS2/blob/main/examples/docker-compose.yml):
```console
# Remember to update passwords in your compose file
$ docker compose --file examples/docker-compose.yml up -d cs2-server
```
You must have at least **40GB** of free disk space! See [System Requirements](./#system-requirements).
**The container will automatically update the game on startup, so if there is a game update just restart the container.**

# Customizing this Container
## Pre and Post Hooks
The container includes two scripts for executing custom actions:
* `/home/steam/cs2-dedicated/pre.sh` is executed before the CS2 server starts
* `/home/steam/cs2-dedicated/post.sh` is executed after the CS2 server stops
When using a persient volume mounted at `/home/steam/cs2-dedicated/` you may edit these scripts to perform custom actions, such as enabling metamod.

This container leans heavily on the work of [CM2Walki](https://github.com/CM2Walki/), especially his [SteamCMD](https://github.com/CM2Walki/steamcmd) container image. GG!
