我正在建立一个停靠的mesos+马拉松集群。我有mesos可以很好地与从属服务器一起工作，但是我在尝试通过发送到marathon的json来推送mesos dns应用程序时不断遇到错误。我发送：

{
    "container": {
        "docker": {
            "image": "192.168.0.38:5000/mesos-dns:generic",
            "privileged": true,
            "forcePullImage": true,
            "network": "BRIDGE"
        }
    },
    "id": "testdns2",
    "env": {
        "MASTERS": "192.168.0.38:5050",
        "RESOLVERS": "192.168.0.38",
        "ZOOKEEPER_MESOS": "zk://192.168.0.38:2181/mesos"
    }
}

为了正确创建应用程序，我在mesos slave上得到了以下错误：

I1204 23:35:59.347939 14308 exec.cpp:134] Version: 0.25.0

docker版本1.8.3，mesos 0.25，marathon 0.9
知道json哪里有问题吗？
