kubernetes - 我无法将我的入口与我的服务连接起来

Question

我的入口和我的服务有问题，当我连接到我的服务器的 IP 时，我无法获得，我重定向到与端口 80 关联的服务，这是我的网站。我把配置文件和入口的描述传给你:

apiVersion: v1

          value: bookstack
        - name: MYSQL_PASS
          value: pass
        - name: MYSQL_ROOT_PASSWORD
          value: root

        name: bookstack
        ports:
        - name: http
          containerPort: 80

apiVersion: v1
kind: Service

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: http
  namespace: bookstack
spec:
  backend:
    serviceName: bookstack
    servicePort: http-port

这是出现在我的入口上的内容:

Name:             http
Namespace:        bookstack
Address:
Default backend:  bookstack:http-port (10.36.0.22:80)
Rules:
  Host  Path  Backends
  ----  ----  --------
  *     *     bookstack:http-port (10.36.0.22:80)
Annotations:
  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？我想避免使用 LoadBalancer 作为服务类型。

Answer 1

主要问题是我没有激活 Google Kubernetes Engine 默认提供的平衡器，没有激活它我无法生成外部 ip，因为没有平衡器。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:LoadBalancer。

在部署 readinessProbe 中激活也很重要
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
