DiscoveryServerUrlInvalidException：必须指定 spring.cloud.kubernetes.discovery-server-url 和有效的 URL

问题描述 投票：0回答：1

我想实现 Spring Cloud Kubernetes。我创建了这个测试项目：

https://github.com/rcbandit111/mockup/tree/master

配置：

spring:
  application:
    name: mockup
  cloud:
    kubernetes:
      discovery-server-url: "http://spring-cloud-kubernetes-discoveryserver"

我还尝试设置服务器网址：

spring-cloud-kubernetes-discoveryserver.default.svc:80

我已经使用此部署文件部署了发现服务器：

发现服务器已成功部署，但我再次遇到此问题。你知道我需要设置什么值吗？

编辑：我尝试部署

image: springcloud/spring-cloud-kubernetes-discoveryserver:3.1.1
（只是将数字更改为上面的 yml 配置）。

我收到此错误堆栈：

问题在于该属性未配置在正确的位置。您需要将其更新为：

spring:
  application:
    name: mockup
  cloud:
    kubernetes:
      discovery:
         discovery-server-url: "http://spring-cloud-kubernetes-discoveryserver"

此外，如果您使用 intellij，这应该会显示配置错误。
