群晖的docker套件从7x以后改名为 Container Manager 实际上还是原来的docker套件
群晖把 Web Station（下文使用web代替）和Container Manager （下文使用docker代替）做了联动，可以通过在docker中配置 【通过 Web Station 设置网页门户】 功能 把docker中的服务直接对公开给外网使用
配置见下图
选择对应的docker容器的端口
门户类型推荐使用 【基于名称】这样就可以直己定义一个三级域名（群晖自带的ddns定义的是二级域名，这个二级域名的证书包含了任意的三级证书）区分不同的服务了
配置好以后 通过配置的主机名就可以直接访问了。
接下来问题就来了，再重启docker 或者 重启系统的时候，你会发现上面配置的映射全都404了，
打开docker套件查看，发现docker中的服务是正常的，
再打开web套件查看，发现配置的门户全都显示服务已禁用
如下图所示
机器每次重启或者docker套件重启，都会导致这个【网络门户】显示【服务已禁用】，我联系过售后技术，也提供了远程链接支持，然并卵，售后技术并没有解决问题
我也尝试翻群晖文档，但是并没有找到相关的api，所以尝试自己在机器上尝试碰运气 看看能不能找到，
最终我在群晖的命令行工具包中找到了一个cli叫 synowebapi 经过不断地尝试，该api是一个万能工具，可以操作群晖的所有功能，基于此工具我写了个自动恢复的脚本（脚本在最后面）
使用该脚本配置了一个定时任务 每分钟触发一次 自动恢复由于docker重启或者机器重启导致的【网络门户】404的问题，配置如下
该脚本使用了如下功能
- 列出系统套件运行状态
- 获取web套件service、portal 列表
- 获取docker套件容器列表
- 停止、运行 docker容器
该脚本会自动检测套件运行状态，并且自动检查对应状态，发现无法访问的【网络门户】则自动重启对应的docker容器
