Deploy and Host

Counter-Strike 2 Dedicated Server — one-click deploy with persistent volume, CSTV support, and zero-downtime updates. Powered by joedwards32/CS2.

After deploying, open CS2 → Play → Community Server Browser → Add Server: :27015

System Requirements

Disk: 30GB+ dedicated volume (CS2 base install ~20GB, grows with maps/workshop content)
Memory: 2 GB RAM minimum (4 GB+ recommended for >10 players)
Network: UDP port 27015 (game), TCP port 27020 (CSTV, optional)
Steam: Valid Game Server Login Token required

About Hosting

This template runs a CS2 dedicated server wrapped around the upstream Docker image. Game data persists on a Railway volume mounted at /home/steam/cs2-dedicated — configs, maps, and logs survive deploys and restarts.

The entrypoint runs as root on boot to chown the Railway volume (root-owned by default) to the steam user, then drops privileges before launching the server. Railway uses TCP port 27015 for healthchecks since the game port is UDP and Railway doesn't support UDP healthchecks.
