私はドッカーには新しく、MongoDBとNode.jsコンテナを作成しました。Docker：mongoのコンテナに接続すると、EHOSTUNREACHに接続します。
まず、mongoDBコンテナを作成して実行しました。
$ docker run mongo
2016-10-04T07:41:12.864+0000 I CONTROL [initandlisten] MongoDB starting : pid=1 port=27017 dbpath=/data/db 64-bit host=f3b51681966e

下記のようにうまくいきます。

さてさて、私はdocker run <server-name>、 としてnodejsサーバーを実行した場合ときにそれは以下のエラーを出力します。
> [email protected] start /usr/src/app
> node ./bin/www
/usr/src/app/node_modules/mongodb/lib/server.js:242
process.nextTick(function() { throw err; })
^

誰かが何か問題を見つけ出すことができますか？
