无法连接到远程 Kubernetes 服务 - SERVICE_UNAVAILABLE

Question

我正在尝试进行以下测试设置：Spring 云网关将消息在内部转发到内部微服务。我尝试了这个网关项目：

内部微服务：

路由设置到网关：

    server:
      port: 8888
      servlet:
        context-path: /api
    spring:
      application:
        name: gateway
      cloud:
        gateway:
          routes:
            - id: mockup
              uri: lb://mockup
              predicates:
                - Path=/api/mockup/admin/**
              filters:
                - RemoveRequestHeader=Cookie
                - name: CircuitBreaker
                  args:
                    name: mockup
                - RewritePath=/api/mockup/admin/(?<path>.*), /mockup/admin/$\{path}

          httpclient:
            wiretap: true
          httpserver:
            wiretap: true

    logging:
      level:
        reactor:
          netty: DEBUG
        org:
          springframework:
            cloud:
              gateway: TRACE

呼叫的 Postman 配置：

`curl --location --request POST 'localhost:8888/api/mockup/admin/greeting'

来自网关的日志文件：
