我为kubernetes的windows播客部署了三个后端服务，以确保它们相互通信。然而，我发现虽然容器、服务、dns和端点都可用并正在运行，但当我尝试从一个容器访问任何服务（内部或外部）到另一个容器时，它不会解析dns并接收“无法解析主机”或“无法连接到网络” 尝试通过（资源服务）访问人员配置或聚合器服务时，收到以下错误>： C:\WINDOWS\system32>kubectl exec-it resources-deployment-6b98d47b5b-ts674 cmd Microsoft Windows[版本10.0.17763.864] （c） 2018年微软公司。版权所有 C:\app\resources>curl curl：（7）连接到172.20.101.110端口8081失败：无法访问网络 C:\app\resources>curl curl：（6）无法解析主机：聚合器服务 C:\app\resources>curl curl：（6）无法解析主机：人员配置服务 C:\app\resources>curl curl：（7）无法连接到172.20.5.156端口8080:网络无法访问 C:\app\resources>ping 10.91.24.250 使用32字节数据ping 10.91.24.250： PING：传输失败。普遍失败 代码很简单，下面是完整的细节 它是一个包含两个windows节点和两个linux节点的混合环境。但是，目前的要求是仅在windows节点上部署以下应用程序。基础设施部署在AWS提供的EKS（弹性Kubernetes服务）上 三种后端（aspnet）服务是：-Kubernetes “库伯内特斯”；Windows播客“；无法相互沟通“；无法解析主机”；|&引用；无法连接到网络“无法访问”；,kubernetes,kubernetes-ingress,kubernetes-pod,amazon-eks,windows-container,Kubernetes,Kubernetes Ingress,Kubernetes Pod,Amazon Eks,Windows Container,我为kubernetes的windows播客部署了三个后端服务，以确保它们相互通信。然而，我发现虽然容器、服务、dns和端点都可用并正在运行，但当我尝试从一个容器访问任何服务（内部或外部）到另一个容器时，它不会解析dns并接收“无法解析主机”或“无法连接到网络” 尝试通过（资源服务）访问人员配置或聚合器服务时，收到以下错误>： C:\WINDOWS\system32>kubectl exec-it resources-deployment-6b98d47b5b-ts674 cmd Microso
