Cannot reach HTTP servlet when building as Dockercontainer

Question

Hi and thanks for taking the time :)

I am currently facing some problems with sbt-native-packager and Docker. I am relatively new to this. Actually, this is my first attempt. And here is my problem: I have an Actor that should respond to HTTP requests. It works great if I run it without dockers. Now I want it to be built as a Dockercontainer (there are server satellites, so I use docker compose). So I use sbt-native-packager, but now that I hit localhost: 4444 I just get "Not Found". So I think something is wrong with my dockerBuild settings. I just can't understand that :(

Here is the code:

Settings

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"))

Addition

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

Docker-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 checkout output:

                "IPAddress": "172.17.0.2",
                ...

            }
        }
    }
