【问题描述】：
我正在尝试创建一个 Kubernetes 集群，这个集群将包含 3 个节点
主节点，我在其中安装和配置 kubeadm 、 kubelete，并在那里安装了我的系统（这是 laravel 开发的 Web 应用程序），
工作节点毫无问题地加入主节点，
我将我的系统部署到 PHP-fpm pod 并创建了服务和水平 Pods Autoscaling
这是我的服务：
PHP LoadBalancer 10.108.218.232 <pending> 9000:30026/TCP 15h app=php
这是我的豆荚

worker nondes 是 taishan，master 是 Kubernetes-master。 这是我的 nginx 配置，它正在向 php 服务发送请求

}
}
问题是我在工作节点上有 3 个 Pod，在主节点上有 5 个 Pod，但是没有请求进入工作节点，所有请求都发给主节点， 我的两个节点都处于就绪状态

我不确定我的错误在哪里，所以请帮助解决这个问题
【问题讨论】：
-
因为你的服务没有正常启动。 > LoadBalancer 10.108.218.232
pending状态表示，服务有问题。 -
感谢回复，我用服务描述更新了问题，但里面没有显示任何错误，请再次检查问题
-
我不确定，那我该怎么办？请帮帮我
-
您能发布您的 pod 部署和服务清单吗？
-
@SachithMuhandiram 你好先生，我刚刚更新了问题请看一下，我在最后一个问题中添加了 yaml 文件
