解析mongo DB无法连接到服务器

Question

我正在尝试在同一台计算机上使用mongo DB在自己的计算机上设置解析服务器。 遵循本教程后， https：//medium.com/@dmathewwws/guide-to-building-your-own-parse-server-aad6568b743d

但是我在解析问题时遇到了一些问题，抱怨无法连接到我的数据库。

2017-07-22T17:41:39.888Z - Error generating response. { MongoError: failed to connect to server [localhost:27017] on first connect
at Pool.<anonymous> (/parse/node_modules/mongodb-core/lib/topologies/server.js:313:35)

Mongo DB似乎正在27017上运行。

Proto Recv-Q Send-Q Local Address           Foreign Address         State       User       Inode       PID/Program name
tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      112        24024       3200/mongod

我也可以通过命令行连接

mongo mongodb://username:pwd@localhost:27017/myDB
MongoDB shell version: 3.2.15
connecting to: mongodb://username:pwd@localhost:27017/myDB
> show collections
test
>

这是我的Dock文件设置。

environment:
  ...
  DATABASE_URI: mongodb://username:pwd@localhost:27017/myDB
mongo:
  image: mongo:3.2.15
  expose:
    - "27017"
  volumes:
    - /mnt/database/mongodb

实际上，mongodb在此许可下位于另一个卷中。

root@test:/mnt/database# ls -lh
total 20K
drwx------ 2 root    root     16K Jul 20 02:34 lost+found
drwxr-xr-x 4 mongodb mongodb 4.0K Jul 22 17:10 mongodb

提前致谢！

对我有用的是用容器链接替换localhost。 我发现本教程很有帮助。

parse-server: 
    ...
    environment:
      ...
      DATABASE_URI: mongodb://mongo:27017/myDB
    links:
        - mongo:mongo
mongo:
  image: mongo
  volumes:
    - /mnt/database/mongodb

TLDR： 教程 ：docker-compose.yml

mongo-parse-server:
    image: mongo
parse-server:
    image: yongjhih/parse-server
    links:
        - mongo-parse-server:mongo

        - FILE_KEY=1DAFE373-5D8A-4E7A-AD05-67C3BA0EDB64
    ports:
        - 1337:1337
parse-dashboard:
