Kubernetes 基于入口路径的路由未按预期工作

Question

我在 kubernetes 集群中安装了NGINX Ingress。当我尝试通过 Ingress Controller 访问微服务端时，它没有按预期工作

我已经部署了两个 Spring Boot 应用程序

入口规则

• 路径 1 -> /客户
  
• 路径 2 -> /prac
  

当我尝试访问其中一项服务时。 http://test.practice.com/prac/practice/getprac，它不起作用

但是当我尝试在没有 Ingress 路径的情况下访问http://test.practice.com/practice/getprac时，它可以工作

我无法理解为什么 Ingress 路径不起作用并且其他服务也会发生同样的情况

微服务1（端口9090）

服务（客户服务和实践服务）

入口

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: practice-ingress
  namespace: practice
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec: 
  rules:

    http: 
      paths:
      - backend:
          serviceName: customer-service
          servicePort: 9090
        path: /customer
      - backend:
          serviceName: prac-service
          servicePort: 8000
        path: /prac

Answer 1

你已经安装了这个nginx ingress

nginx.ingress.kubernetes.io/rewrite-target: /注释要正常工作，您需要安装此nginx ingress。

/prac解决此问题的另一种方法是在 spring 应用程序中配置 contextPath
