# ============================================
# 快速 Docker 构建脚本 - 使用优化版 Dockerfile
# 使用文档：
#   首次使用: bash init-dependencies.sh
#   构建单个: bash build-docker-optimized.sh gateway:1.0.0
#   构建多个: bash build-docker-optimized.sh gateway:3.0.2 order-service:3.0.5 payment-service:3.0.5
#   自定义仓库: bash build-docker-optimized.sh gateway:1.0.0 -r myregistry.com
# ============================================

set -o pipefail  # 管道中任何命令失败都会导致脚本退出

# 颜色定义
RED='\033[0;31m'

YELLOW='\033[1;33m'
BLUE='\033[0;34m'
CYAN='\033[0;36m'
NC='\033[0m'  # No Color

# 函数：打印颜色信息

服务简称:
  gateway         - shop-recycle-gateway 网关服务
  order           - shop-recycle-order-service 订单服务
  order-service   - shop-recycle-order-service (别名)
  payment         - shop-recycle-payment-service 支付服务
  payment-service - shop-recycle-payment-service (别名)

全局选项:
  -h, --help              显示此帮助信息
  -r, --registry ADDR     镜像仓库地址 (默认: harbor.stardance)
  --no-cache              构建时不使用缓存
  --push                  构建完成后自动推送到镜像仓库

示例:
  # 构建单个服务
  bash $0 gateway:1.0.0
  
  # 构建多个服务（依次进行）
  bash $0 gateway:3.0.2 order-service:3.0.5 payment-service:3.0.5
  
  # 自定义镜像仓库
  bash $0 gateway:1.0.0 -r myregistry.com
  
  # 禁用缓存并推送
  bash $0 gateway:1.0.0 --no-cache --push
