在docker容器中使用akka应用程序的问题

Docker 前端之家
前端之家收集整理的这篇文章主要介绍了在docker容器中使用akka应用程序的问题，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

我们有一个在非集群模式下运行的akka​​应用程序(不是akka集群).
我们正在尝试将此应用程序停靠,并遇到问题.我们正在使用docker主机网络,并且由于各种其他原因,我们尚未准备好使用其他类型的网络.

应用程序绑定到端口9080上的0.0.0.0接口,并自行执行简单的http运行状况检查.
此运行状况检查失败,因为我们看到连接重置错误.我们只在docker容器内看到这个.

在启动期间,应用程序绑定到0：0：0：0：0：0：0：0：9080.
2018-04-13T08：29：54.921-0700 [INFO] – 绑定到/ 0：0：0：0：0：0：0：0：9080

版本：
akka – 2.3.0
喷雾 – 1.3.2
在docker容器内的alpine linux上运行.

任何指针都会有所帮助.提前致谢.

最佳答案
在docker-compose文件中,在appname下定义端口映射.

  1. ports:
  2.     9080:9080
