scala – 构建为Dockercontainer时无法访问HTTP servlet

目前我正面临着sbt-native-packager和Docker的一些问题.我对此比较陌生.实际上,这是我的第一次尝试.这是我的问题：
我有一个Actor,它应该响应HTTP请求.如果我在没有Docker的情况下运行它,它工作正常.现在我希望它被构建为Dockercontainer(有几个同伴,所以我使用docker compose).因此,我使用sbt-native-packager,但现在我点击了
localhost：4444我刚收到“Not found”.所以我认为我的dockerBuild设置有问题.我只是找不到:(

这里有一些代码：

设置

lazy val graphiteprocSetting = eventprocSettings ++ Seq(
name := "graphite-processor",dockerBaseImage := "nimmis/java:oracle-8-jdk",daemonUser in Docker := "root",debianChangelog in Debian := Some(file("*")),mainClass in Compile := Some("*.StreamProcessorKafkaToGraphite"))

建立

lazy val graphiteproc =  Project(                                                                          
    id = "graphiteproc",base = file("modules/graphiteproc"),settings = graphiteprocSetting                               
  ).enablePlugins(DebianPlugin,JavaServerAppPackaging,DebianDeployPlugin,DockerPlugin,BuildInfoPlugin)

泊坞窗,compose.yml

graphiteprocessor:
  # TODO insert correct version via sbt
  image: graphite-processor:0.1.13-SNAPSHOT
  volumes:
    - ./conf:*
  environment:
    JAVA_OPTS: "-Dconfig.file=*"
  ports:
    - "4444:4444"
  links:
      - graphite
      - kafka

docker的输出检查：

            }
        }
    }
