入口没有地址

Question

我的机器上有一个小的 k8s 集群，我尝试做一些东西来学习，但我现在正在堆叠。

我有 2 个应用程序，一个 mysql 和另一个 wordpress，它们运行良好。当我为 wordpress 提供 LoadBalancer 类型时，它占用了一个 ip，我可以在我的浏览器中看到。

所以我想创建一个 Ingress 并通过主机名调用，但 Ingress 不使用 Loadbalancer IP.. 我做错了什么吗？

这是我的 Ingress 配置

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: wp-ingress
  kubernetes.io/ingress.class: nginx
  labels:
    name: wp-ingress
spec:
  rules:
  - host: wordpress.pandora.local
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: wp-svc
            port: 
              number: 80
  - host: phpmyadmin.pandora.local
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: phpmyadmin-svc
            port: 
              number: 80

和问题

# kg ingress
NAME         CLASS    HOSTS                                              ADDRESS   PORTS   AGE
wp-ingress   <none>   wordpress.pandora.local,phpmyadmin.pandora.local             80      38m

我正在使用 Metallb 作为负载均衡器，我知道它可以工作是因为 wordpress，但是如果你想看

我该如何解决问题

Answer 1

我解决了。感谢您的帮助:) 问题即将进入 class.

kind: Ingress
metadata:
  name: wp-ingress
spec:
  rules:
  - host: wordpress.pandora.local
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: wp-svc
            port:
              number: 80
  - host: phpmyadmin.pandora.local
    http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: phpmyadmin-svc
            port:
              number: 80
  ingressClassName: nginx

我添加了最后一行 ingressClassName: nginx 定义并且成功了！

kg ingress
NAME         CLASS   HOSTS                                              ADDRESS         PORTS   AGE
wp-ingress   nginx   wordpress.pandora.local,phpmyadmin.pandora.local   192.168.88.20   80      5h19m
