在我的环境中，以独立模式运行mesos slave、mesos master marathon和mesos dns。我将mysql应用程序部署到marathon以作为docker容器运行。
mysql应用程序配置如下。

{
    "id": "mysql",
    "cpus": 0.5,
    "mem": 512,
    "instances": 1,
    "container": {
        "type": "DOCKER",
        "docker": {
            "image": "mysql:5.6.27",
            "network": "BRIDGE",            
              "portMappings": [
                {
                  "containerPort": 3306,
                  "hostPort": 32000,
                  "protocol": "tcp"
                }
                ]
        }
    },
    "constraints": [
            [
              "hostname",
              "UNIQUE"
            ]],
    "env": {
        "MYSQL_ROOT_PASSWORD": "password"   
    },
      "minimumHealthCapacity" :0,
      "maximumOverCapacity" : 0.0
}

然后我部署了一个名为mysql client的应用程序。mysql客户端应用程序需要连接到mysql应用程序。
mysql应用程序配置如下。

{
    "id": "mysqlclient",
    "cpus": 0.3,
    "mem": 512.0,
    "cmd": "/scripts/create_mysql_dbs.sh",
    "instances": 1,
    "container": {
        "type": "DOCKER",
        "docker": {
            "image": "mysqlclient:latest",
            "network": "BRIDGE",            
            "portMappings": [{
                "containerPort": 3306,
                "hostPort": 0,
                "protocol": "tcp"
            }]
        }
    },
    "env": {
        "MYSQL_ENV_MYSQL_ROOT_PASSWORD": "password",
        "MYSQL_PORT_3306_TCP_ADDR": "mysql.marathon.slave.mesos.",
        "MYSQL_PORT_3306_TCP_PORT": "32000"     
    },
      "minimumHealthCapacity" :0,
      "maximumOverCapacity" : 0.0
}

我的mesos dns config.json。如下

{
  "zk": "zk://127.0.0.1:2181/mesos",
  "masters": ["127.0.0.1:5050"],
  "refreshSeconds": 60,
  "ttl": 60,
  "domain": "mesos",
  "port": 53,
  "resolvers": ["127.0.0.1"],
  "timeout": 5,
  "httpon": true,
  "dnson": true,
  "httpport": 8123,
  "externalon": true,
  "listener": "127.0.0.1",
  "SOAMname": "ns1.mesos",
  "SOARname": "root.ns1.mesos",
  "SOARefresh": 60,
  "SOARetry":   600,
  "SOAExpire":  86400,
  "SOAMinttl": 60,
  "IPSources": ["mesos", "host"]
}
I can ping with service name mysql.marathon.slave.mesos. from host machine. But when I try to ping from mysql docker container I get host unreachable. Why docker container cannot resolve hsot name?

我尝试将dns参数设置为apps。但它不起作用。
编辑：
我可以ping mysql.marathon.slave.mesos。来自主/从主机。但是我不能从mysqlclient docker容器ping。上面写着无法到达。我怎样才能解决这个问题？
