es部署在docker里面，让es固定在一台slave上跑

在把es的镜像推到mesos环境上的时候，部署的json配置加如下的配置，让其固定在一台slave上

   "parameters": [

                {"key":"dns","value":"192.168.42.1"},

                { "key": "volume", "value": "/data/esdata_log:/elasticsearch/data" }

      ]

完整配置如下：     

{

  "container": {

    "type": "DOCKER",

    "docker": {

      "image": "registry.12301.io/elasticsearch-data:v21",

      "network": "BRIDGE",

      "portMappings": [

        { "containerPort": 9200, "hostPort": 0, "servicePort": 0, "protocol": "tcp" },

        { "containerPort": 9300, "hostPort": 0, "servicePort": 0, "protocol": "tcp" }

      ],

      "parameters": [

                {"key":"dns","value":"192.168.42.1"},

                { "key": "volume", "value": "/data/esdata_log:/elasticsearch/data" }

      ]

    }    

  },

  "constraints": [["hostname", "UNIQUE"],["es", "CLUSTER", "es-log"]],

  "id": "elasticsearch-log",

  "instances": 2,

  "cpus": 0.5,

  "mem": 1024,

  "env":{

    "MARATHON":"10.10.115.48:8080"

  },

  "upgradeStrategy": {
