HomeDash/deploy/zd-host.sh

#!/usr/bin/env bash
# HomeDash host 模式部署（切换成"单容器即入口"之后使用）
#
# 为什么不能用 deploy/zd.sh：
#   zd.sh 靠"改门户 nginx 的上游端口 + 双端口轮换"实现零停机，前提是入口
#   （portal-nginx）独立于应用容器。切换之后入口就是 navi 容器本身，
#   host 网络下端口即入口，没有可轮换的第二组端口 —— 那套脚本会失效。
#
# 本脚本的策略（用户已明确接受数秒闪断）：
#   构建 → 上传 → 停旧容器 → 起新容器（host 网络）→ 全面校验 → 改名
#   任一步失败：删掉新容器、把旧容器改名回去并启动（自动回滚）
