C# redis背板无法正常工作的横向扩展信号器服务器（vue前端）

c# vue.js websocket signalr

C# redis背板无法正常工作的横向扩展信号器服务器（vue前端）,c#,vue.js,websocket,signalr,C#,Vue.js,Websocket,Signalr,感谢您的回答我基于运行在docker（debian）上的.NETCore3.1创建了一个signalr后端服务器。当我只在kubernetes上创建单服务器部署时，它工作得很好。但当我将副本数增加到1以上时，它的工作方式不正确。看起来redis背板不工作，导致多台服务器之间无法进行通信根据官方文档，我安装了nuget软件包： <PackageReference Include="Microsoft.AspNetCore.SignalR.StackExchangeRedi

感谢您的回答
我基于运行在docker（debian）上的.NETCore3.1创建了一个signalr后端服务器。当我只在kubernetes上创建单服务器部署时，它工作得很好。但当我将副本数增加到1以上时，它的工作方式不正确。看起来redis背板不工作，导致多台服务器之间无法进行通信
根据官方文档，我安装了nuget软件包：

好吧，都是我的错。在仔细阅读官方文件后，我找到了原因。我忽略了最后一点：

针对我的情况，解决方案是将nginx入口配置为启用粘性会话，如下所示：

nginx.ingress.kubernetes.io/affinity: cookie nginx.ingress.kubernetes.io/affinity-mode: balanced nginx.ingress.kubernetes.io/session-cookie-expires: "86400" nginx.ingress.kubernetes.io/session-cookie-max-age: "86400"

将上面的配置添加到ingress yaml中的元数据：annotations节点中

我尝试了找到的所有解决方案，但都没有用。我使用redis cli monitor监视redis io，我没有发现io记录。所以我想原因是redis背板不工作导致无法连接多个服务器信号器通信。谢谢大家查看了这个问题。
