Service Fabric 无法连接到 UDP 上的来宾可执行文件（Unreal Engine 服务器）

Question

我正在尝试将 Unreal Server 来宾可执行文件部署到 Service Fabric。我一直在关注这个博客 post:

http://haishibai.blogspot.com/2017/03/setting-up-highly-available-minecraft.html

除非我不使用容器并使用基于 Windows 的服务。

在本地集群上一切正常。我可以从客户端连接到已部署的服务器。

尝试连接到远程服务器时，无法连接。

查看我的服务结构管理页面时，我的服务器进程似乎正在运行（它有正确的进程 ID）。

在我的 LoadBalancing 服务中，我在 UDP/7777 上进行了端口转发，尽管 HealthProbes 在 TCP 上（select UDP 没有选项，我不知道那是不是 mnatter）。

这是我的服务清单：

Answer 1

1.You 似乎缺少服务 endpoint 配置。

<Resources>
  <Endpoints>
    <!-- This endpoint is used by the communication listener to obtain the port on which to 
         listen. Please note that if your service is partitioned, this port is shared with 
         replicas of different partitions that are placed in your code. -->
    <Endpoint Name="ServiceEndpoint" Port="7777" />
  </Endpoints>
</Resources>

负载均衡器上的探测不支持 UDP。因此，公开第二个使用 tcp 的服务端点，就像健康端点一样。
