Spring 为什么在eureka中docker寄存器中的应用程序喜欢一些散列而不是ip地址

我需要告诉运行在Docker中的Eureka客户端使用主机的IP注册其服务。我用了下面的，但不起作用

这是来自尤里卡的信息

网关服务在没有docker容器的情况下运行，并且它具有IP地址而不是docker容器id

我有Eureka客户端的下一个配置（也有帐户服务）

和尤里卡配置：

eureka:
  instance:
    preferIpAddress: true
  client:
    register-with-eureka: false
    fetch-registry: false
    server:
      waitTimeInMsWhenSyncEmpty: 0

帐户服务的Docker文件：

FROM openjdk:8-jdk-alpine
EXPOSE 8081
COPY /build/libs/account-service-1.0-SNAPSHOT.jar .
ENTRYPOINT ["java","-jar","account-service-1.0-SNAPSHOT.jar"]

如果我的理解正确，由于这个问题，网关服务也无法工作，因为它不知道任何具有a462e5bd6528（容器id）名称的主机

/帐户服务的eureka/app看起来像

<name>ACCOUNT-SERVICE</name>
<instance>
<instanceId>7186158a6d3a:account-service:8081</instanceId>
<hostName>172.17.0.2</hostName>

所以我将eureka配置更改为

eureka:
  instance:
    preferIpAddress: true
  client:
    register-with-eureka: false
    fetch-registry: true
    server:
      waitTimeInMsWhenSyncEmpty: 0

获取注册表：true

而且效果很好

我在Eureka有相同的服务描述

但现在网关服务可以将请求路由到帐户服务

使用--网络主机运行docker时，它将选择主机ip地址

，这只是一个实例id，而不是注册的主机或ip。/eureka/apps怎么说？我已经用关于/eureka/apps say@spencer的信息更新了这个问题，所以主机名和ip地址注册为

172.17.0.2

Yep，但我需要我的本地ip地址，比如192.168.10.101。你需要设置它

eureka.instance.ip address=…
