fix(deploy): nginx 上游运行期重新解析 + 就绪探针;内存上限按 8C/32G 重新分配
问题:容器重建换 IP 后,网关与 admin-ui 仍往旧 IP 打,/openapi 与 /api
整片 502,必须手动重启 nginx 容器才恢复(2026-11-03 实机踩到)。

编排
- admin-svr / openapi / admin-ui / docs 增加 healthcheck
- admin-ui、gateway、nginx 改 depends_on: condition: service_healthy,
  保证 nginx 启动时后端已就绪
- 新增 deploy/compose.memlimit.yml(原来只存在于某台演示机上):
  全套上限 8.5G、实测常驻 2G,留给同机其它服务 20G+;
  MySQL buffer pool 128M→768M、max_connections 151→300

nginx
- gateway / admin-ui / iotlcm.conf 示例 统一改 resolver 127.0.0.11 valid=10s
  + upstream zone/resolve:运行期跟随 IP 变化,不必重启(实测 6s 内自愈)

# 单端口入口(默认对外 5051)
#
# 用途:把管理端、文档站、OpenAPI 收在一个端口下,便于在外部网关 / DNS
# 只暴露一个地址。编排里由 gateway 服务(profile: with-gateway)加载本文件,
# 容器内监听 80,宿主机发布端口用 GATEWAY_PORT 控制(默认 5051)。
#
# docker compose --profile with-gateway up -d
# GATEWAY_PORT=8088 docker compose --profile with-gateway up -d
#
# 路由:
# / -> 管理端(admin-ui,内部已代理 /api/ 到 admin-svr)
# /docs/ -> 文档站(docs)
# /openapi/ -> 对外 API(openapi)
# /route/open/ -> 运营商能力代理(openapi)
#
# 小程序 / H5 端的静态资源是根路径部署的,不能挂在同一域名的子路径下,
# 需要单独域名或单独端口(见 config/nginx/iotlcm.conf 的 app 段)。
# DNS 解析:nginx 默认只在启动时把 upstream 主机名解析一次,容器重建/重启换了 IP
# 就一直往旧地址打(2026-11-03 踩到:整站 /openapi 全 502,重启网关才恢复)。
# 127.0.0.11 是 Docker 内置 DNS;下面的 resolve + zone 让它在运行期自动跟随。
