#!/usr/bin/env bash
# ============================================================
# 服务器侧：加载镜像包并按需启动（无需联网、无需 sdk 镜像）
#
# 用法：
#   # 1) 加载完整包并启动全部
#   bash deploy/load-and-up.sh deploy/dist/buyu-images-<tag>.tar
#
#   # 2) 只加载某个服务的包并只重启该服务（增量更新）
#   bash deploy/load-and-up.sh deploy/dist/buyu-images-admin-<tag>.tar admin
#   bash deploy/load-and-up.sh deploy/dist/buyu-images-admin-fishgame-<tag>.tar admin fishgame
#
# 说明：镜像内的配置（网关 ocelot 下游改写、捕鱼对外地址）已在构建时固化；
#       服务器只做「加载镜像 + 按需重启」，不涉及编译。
