尤里卡客户在docker集装箱
我有一个尤里卡服务器和两个rest服务（尤里卡客户端）在docker集装箱运行。 如果第一个服务试图访问第二个服务，我得到一个UnknownHostException。 原因是这些服务使用dns服务器无法parsing的容器主机名在eureka服务器上注册。
我认为解决scheme可能是设置docker集装箱的主机名称。 所以我用docker和-h标志来设置主机名： docker run -h project-dev.net9.mycompany.com
但是现在这些服务甚至不能在尤里卡服务器上注册。 我得到这个例外：

域project-dev.net9.mycompany.com可以在我们的networking访问，我可以ping它。
我也可以访问http://project-dev.net9.mycompany.com:8761/上的eureka仪表板。 所以尤里卡服务器运行正常。
我很感激任何提示。
您是否尝试将eureka.instance.prefer-ip-address设置为true？ 客户端将注册自己的IP地址，而不是它的主机名。
每个build议在这里： 没有答案的问题，但问题解决了意见
