AzerothCore-RealmMaster/deploy.sh

#!/bin/bash
#
# High-level orchestrator for module-aware deployments.
# 1. Ensures AzerothCore source repo is present
# 2. Runs ac-modules to sync/clean module checkout and configs
# 3. Rebuilds source images when C++ modules demand it
# 4. Stages target compose profile and optionally tails worldserver logs

This command automates deployment: sync modules, stage the correct compose profile,
and optionally watch worldserver logs.

Image Requirements:
This script assumes Docker images are already built. If you have custom modules:
• Run './build.sh' first to build custom images
• Standard AzerothCore images will be pulled automatically
