Setup in 4 Steps

Skip the manual SteamCMD installation, port forwarding, and systemd configuration. Install on your own computer and start hosting instantly.

Step 01

Create a GameCP Account

GameCP gives you a full control panel with Docker containerization, file management, automatic port forwarding, and automatic updates — all built in.

Step 02

Connect Your Hardware

Install GameCP on your own desktop, laptop, VPS, or dedicated machine. One-line install — no SSH expertise needed.

GameCP installs Docker, configures networking, and sets up automatic port forwarding so your friends can connect instantly. Start hosting from your own PC and scale to a VPS later. Supports Windows, macOS, and Linux.

Step 03

Deploy Left 4 Dead 2

Select "Left 4 Dead 2" from the template library and hit deploy. GameCP handles SteamCMD (App ID: 222860), ports, startup commands, and all configuration automatically.

Includes pre-configured server.cfg. Uses the games:source image. ~5 GB storage.

Step 04

Start Playing

Hit start and share your server address. Automatic port forwarding handles the rest — no router config needed.

GameCP provides live SOURCE console access from your browser. Your friends connect using the address GameCP gives you.

  +force_install_dir /opt/gameserver \
  +login anonymous \
  +app_update 222860 validate \
  +quit

Step 3

terminal

sudo ufw allow 27015/both

27015/BOTH(PORT)

Step 4

Launch the Server

Create the startup script

terminal

# Create the startup script
cat > /opt/gameserver/start.sh << 'EOF'
./srcds_run -game left4dead2 \
-console \
-usercon \
-port 27015 \
+map c1m1_hotel \
+maxplayers 8 \
+sv_setsteamaccount \
+ip 0.0.0.0 \
+hostname "" \
+exec server.cfg \
-strictportbind \
-norestart
EOF
chmod +x /opt/gameserver/start.sh

Run the container

terminal

docker run -d \
  --name left-4-dead-2-server \
  -p 27015:27015/both \
  -e MAX_PLAYERS="8" \
  -e ALLOW_LOBBY_CONNECT="0" \
  -e SRCDS_MAP="c1m1_hotel" \
  -e GAME_MODE="coop" \
  -e DIFFICULTY="Normal" \
  -e AUTO_UPDATE="0" \
  -v /opt/gameserver:/opt/gameserver \
  -w /opt/gameserver \
  ghcr.io/ptero-eggs/games:source \
  ./start.sh
