# FortiChain Server Docker Build Script
# ====================================
# This script builds multi-stage Docker images for the FortiChain Server
# supporting both Debian and Alpine Linux base images with Rust nightly
# for edition 2024 support.
#
# Features:
# - Multi-stage builds for minimal production images
# - Size comparison between Debian vs Alpine variants
# - Comprehensive deployment instructions
# - Docker and docker-compose integration
#
# Usage: ./build.sh
#
# Authors: Ebube Onuora, Abraham Ujah
