Host a Project Zomboid Dedicated Server

# Create the startup script
cat > /opt/gameserver/start.sh << 'EOF'
#!/bin/bash

# 1. Path & Environment Setup
# Move to the container root to ensure relative paths work
cd /home/container || exit 1

# Update PATH and Library paths correctly
export PATH="./jre64/bin:"
export LD_LIBRARY_PATH="./linux64:./natives:.:./jre64/lib/server:"

# 2. Fix the LD_PRELOAD Warning
# We check if the file exists before preloading to avoid 'cannot open shared object' errors
JSIG="./jre64/lib/server/libjsig.so"
if [ -f "" ]; then
export LD_PRELOAD=":"

# 3. Memory & Performance for Ryzen 7900
# Zomboid is heavy on RAM; 8GB is standard, but you can bump -Xmx if needed.
JAVA_ARGS="-Xmx8g -XX:+UseZGC -Djava.awt.headless=true -Dzomboid.steam=1 -Dzomboid.znetlog=1"

# 4. The Launch Command
# FIX: Changed -cachedir from '/.cache' to 'Zomboid' to stay inside /home/container
# NOTE: -servername uses PZ_CONFIG_NAME (default: servertest) which determines
# which .ini and _SandboxVars.lua files PZ reads. This is NOT the public display name.
