我有一个服务发现和一个客户端在 Rancher 中注册到这个服务器。它是这样的：

eureka-server:
  ports:
  - 8761:8761/tcp
  labels:
    io.rancher.container.pull_image: always
    io.rancher.container.start_once: 'true'
  tty: true
  image: luizkowalski/eureka-server
  stdin_open: true
  net: host
edge-server:
  ports:
  - 8080:8080/tcp
  labels:
    io.rancher.container.pull_image: always
    io.rancher.container.start_once: 'true'
  tty: true
  image: luizkowalski/edge-server
  links:
  - eureka-server:discovery
  stdin_open: true
  net: host

给定链接，我应该能够eureka-server使用 hostname连接discovery，就像http://discovery:8761/eureka但我得到了

当我managed在 Rancher 中使用网络时它可以工作，但结果是，我的服务发现将我的内部 ips 暴露给负载均衡器（172.xxx.xxx.xx）并且我无法调用我的注册服务是否缺少任何配置？

为了访问提供链接名称解析的 Rancher DNS，您需要io.rancher.container.dns:true使用 net:host 将标签添加到服务器。
