HLDS Docker - Crossfire 24/7

Half-Life Dedicated Server as a Docker image

Probably the fastest and easiest way to set up an old-school Half-Life Deathmatch Dedicated Server (HLDS) running Crossfire map 24/7 with 15-minute rounds.

You don't need to know anything about Linux or HLDS to start a server. You just need Docker and this image.

Features

✅ Included:

• 15-minute rounds with automatic map cycling
• Crossfire map only
• Customizable server settings via .env
• Auto-restart on crash
• MetaMod + AMX Mod X 1.9 installed
• Built-in timeleft command (type in chat to see remaining time)
• Admin commands ready

Quick Start

Docker Hub Image (Recommended)

The latest image of this repo is available in docker hub josejsalinas/hl-server

docker run -d --name halflife-server \
  -p 27015:27015 \
  -p 27015:27015/udp \
  -e SERVER_NAME="My Crossfire Server" \
  -e MAX_PLAYERS=16 \
  -e RCON_PASSWORD=changeme \
  josejsalinas/hl-server:latest

Or use docker compose with the hub image by creating a docker-compose.yml:

services:
  halflife:
    image: josejsalinas/hl-server:latest
    container_name: halflife-server
    restart: unless-stopped
    ports:
      - "27015:27015/tcp"
      - "27015:27015/udp"
    environment:
      - SERVER_NAME=${SERVER_NAME:-Half-Life Crossfire Server}
      - MAX_PLAYERS=${MAX_PLAYERS:-16}
      - SERVER_PASSWORD=${SERVER_PASSWORD:-}
      - RCON_PASSWORD=${RCON_PASSWORD:-changeme}
      - WELCOME_MESSAGE=${WELCOME_MESSAGE:-Welcome to Crossfire!}
