Question

我的入口和服务有问题，当我连接到服务器的IP时，我无法重定向到与端口80相关联的服务，这是我的网站。我向您传递了配置文件和入口的描述：

这是我的入口上显示的内容：

  kubectl.kubernetes.io/last-applied-configuration:  {"apiVersion":"extensions/v1beta1","kind":"Ingress","metadata":{"annotations":{},"name":"http","namespace":"bookstack"},"spec":{"backend":{"serviceName":"bookstack","servicePort":"http-port"}}}

Events:  <none>

它不返回任何外部IP来连接我，为什么会这样？我想避免将LoadBalancer用作服务类型。

Answer 1

将没有外部IP，因为NodePort代表群集上该特定端口上的所有节点。因此，从本质上讲，您必须将外部负载平衡器或该流量源指向该特定NodePort上群集中的每个节点。

请注意，如果您使用的是ExternalTrafficPolicy=Local，则只有具有服务吊舱的节点才会答复。

Answer 2

主要问题是我没有激活Google Kubernetes Engine默认提供的均衡器，没有激活它，因为没有均衡器，所以我无法生成外部ip。有两种解决方案，要么激活GKE的默认负载均衡器，要么创建一种服务类型：LoadBalancer。

在准备就绪状态下也要激活激活探针和livenessProbe。

一个例子：

    readinessProbe:
      httpGet:
        path: /login
        port: 80
      initialDelaySeconds: 5
      timeoutSeconds: 1
      periodSeconds: 15
    livenessProbe:
      httpGet:
        path: /login
        port: 80
      initialDelaySeconds: 15
      timeoutSeconds: 1
      periodSeconds: 15

我无法将入口与服务连接
