MUP部署：MongoError：第一次连接时无法连接到服务器[mongodb：27017] [MongoError：getaddrinfo ENOTFOUND mongodb mongodb：27017]

Question

我在mup deploy时面临下面的问题。

[18.220.xxx.xxx] x Verifying Deployment: FAILED

    -----------------------------------STDERR-----------------------------------
    meteor app on port:80

    /built_app/programs/server/node_modules/fibers/future.js:313
                                                    throw(ex);
                                                    ^
    MongoError: failed to connect to server [mongodb:27017] on first connect [MongoError: getaddrinfo ENOTFOUND mongodb mongodb:27017]

        at Object.onceWrapper (events.js:316:30)
        at emitOne (events.js:115:13)

    => Redeploying previous version of the app

    -----------------------------------STDOUT-----------------------------------

    To see more logs type 'mup logs --tail=100'

    ---------------------------------------------------------------------------

而且当我试图列出所有容器时，mongo没有占用任何端口。怎么办？

sudo docker ps
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS                            PORTS                  NAMES

docker run的结果是：

docker exec -it mongodb mongo
Error response from daemon: Container 789025a88f4a506112fc16c13aa33b71922c267bdfe650bc667109d5fdae076e is not running

mup.js env变量

env: {      
      ROOT_URL: 'http://example.com',      
      MONGO_URL: 'mongodb://127.0.0.1:27017/example',      
      PORT: 3003,   
 },

提前致谢！
