scala – Docker Akka-Http应用程序端点无法访问

object Main extends App with Routes {
  private implicit val system = ActorSystem()
  protected implicit val executor: ExecutionContext = system.dispatcher
  protected implicit val materializer: ActorMaterializer = ActorMaterializer()
  protected val log: LoggingAdapter = Logging( system,getClass )

  log.info( "starting server" )
  Http().bindAndHandle( logRequestResult("log",Logging.InfoLevel)( allRoutes ),"localhost",8080 )
  log.info( "server started,awaiting requests.." )
}

(allRoutes混合在via Routes中,但只是一个虚拟端点,将一个简单的case类序列化为JSON响应)

如果我使用sbt启动它,那么端点工作正常(例如http://localhost:8080/colour/red).

我现在正在尝试将其打包到Docker容器中来运行它 – 我已经读过像http://yeghishe.github.io/2015/06/24/running-akka-applications.html这样的东西并添加了sbt-native-package插件(http://www.scala-sbt.org/sbt-native-packager/formats/docker.html#customize).

现在我运行sbt docker：publishLocal

我可以看到已创建docker镜像：

REPOSITORY             TAG                 IMAGE ID            CREATED             SIZE
sample-rest-api        0.0.1               3c6ee44985b4        9 hours ago         714.4 MB

如果我现在开始我的图像,映射8080端口如下：

docker run -p 8080:8080 sample-rest-api:0.0.1

我看到我通常在启动时看到的日志输出,所以它看起来已经开始正常,但是,如果我然后尝试访问与之前相同的URL我现在得到响应

“加载页面时出错：连接已重置”

如果我检查docker ps,我看到图像正在运行,并且端口按预期映射：

CONTAINER ID        IMAGE                   COMMAND                 CREATED              STATUS              PORTS                    NAMES

我在Ubuntu 16.04上运行 – 任何人都有任何想法？
