Service Fabric 多实例问题

Question

我注意到，当我发布我的 Service Fabric（在 5 节点集群模式下）应用程序（具有 2 个无状态服务）时，它立即在 5 个节点上运行s。

我的 ApplicationManifest.xml 有这个：

<Parameters>
         <Parameter Name="MyStateless1_InstanceCount" DefaultValue="-1" />
         <Parameter Name="MyStateless_InstanceCount" DefaultValue="-1" />
</Parameters>

我的 Local.5Node.xml 有这个：

<Parameters>
         <Parameter Name="MyStateless1_InstanceCount" Value="1" />
         <Parameter Name="MyStateless_InstanceCount" Value="1" />
</Parameters>

我尝试以多种方式更改两个 xml 中的值，但它总是从 5 个节点开始。我注意到这一点是因为我在一个端口上有一个服务 ServiceInstanceListener 并且每次我收到警告因为它试图在 5 个节点上启动。我该如何解决这个问题？

我也是 Service Fabric 的新手，所以我还有几个问题：

是否可以同时发布几个应用程序，比如一些way/command同时发布它们，或者是唯一的手动方式一个一个地发布？
当我有状态服务时，我明白它需要在 5 节点集群模式下运行并且在至少三个节点上需要运行s。这是正确的吗？

您介意分享您的结构浏览器的快照吗？我在 5 个节点中使用我的示例尝试了您的场景，它按预期工作运行每个服务的 1 个实例，如下所示。另外，这是我的代码示例：https://github.com/krish-gh/SFSample

当我在应用程序参数文件部分发布应用程序时，默认选择了 ApplicationParametas\Cloud.xaml 而不是 ApplicationParametas\Local.5Node.xaml
