事故：门户首页改为由 admin-server 渲染（/portal-page）后，镜像里的门户模板带 HTML 占位符，而线上 gateway.conf 仍是上一版生成的（未引用渲染器），导致 门户页占位符裸露、标题为空。 在 zd-host.sh 的入口自检之后加入 apply 步骤（用同一份 env 里的 admin token）， 失败即中止并回滚，避免镜像已更新但配置没跟上这类静默不一致。

# 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）
