Docker + Marathon:如何进行端口映射？

Question

我正在尝试在我的基础设施上启动rstudio.

如果我做 :

sudo docker run -d -p 8787:8787 192.168.0.38:5000/rocker/rstudio

然后我的rstudio在我的服务器上正常运行.但我有mesos和马拉松,并希望用这个docker命令制作一个Marathon的应用程序.

我找不到正确映射端口的方法.

我试过了 :

{
  "type": "DOCKER",
  "volumes": [],
  "docker": {
    "image": "192.168.0.38:5000/rocker/rstudio",
    "network": "HOST",
    "privileged": true,
    "parameters": [
      {
        "key": "p",
        "value": "8787:8787"
      }
    ],
    "forcePullImage": true
  }
}

跳跃我会工作,但它永远不会开始.

我试过了:

{
  "type": "DOCKER",
  "volumes": [],
  "docker": {
    "image": "192.168.0.38:5000/rocker/rstudio",
    "network": "HOST",
    "portMappings": [
      {
        "containerPort": 8787,
        "hostPort": 8787,
        "servicePort": 10003,
        "protocol": "tcp"
      }
    ],
    "privileged": true,
    "parameters": [],
    "forcePullImage": true
  }
}

哪个不是更好.

你建议我转换这个工作的docker命令哪个json:

sudo docker run -d -p 8787:8787 192.168.0.38:5000/rocker/rstudio

端口映射(与Docker一样)仅与BRIDGE网络模式相关,另请参阅Marathon doc.在您的情况下,以下应该工作:

...
"container": {
  "type": "DOCKER",
  "docker": {
    "network": "BRIDGE",
    "portMappings": [
      {
        "protocol": "tcp",
        "containerPort": 8787,
        "hostPort": 8787
      }
    ]
  }
},
...
