Cannot access Docker container when starting via plugin

Hi,

I am facing a probably very basic problem with PyCharm or - more specific - the Docker Integration plugin. We have a working Dockerfile which creates a basic Hello World web app. We can access the app successfully after starting the comtainer from command line. If we use the command line parameters to let the plugin create a JSON file for us the web app is not accessible.

Command line: docker run -p 8080:8080 image_name

The JSON file contains:

{

  "AttachStdin" : true,

  "OpenStdin" : true,

  "Image" : "",

  "Volumes" : { },

  "ExposedPorts" : { },

  "HostConfig" : {

    "Binds" : [ ],

    "PortBindings" : {

      "8080/tcp" : [ {

        "HostIp" : "",

        "HostPort" : "8080"

      } ]

    }

  },

  "_comment" : ""

}

What am I missing here?
