docker/nodejs/mongodb部署: MongooseError [MongooseServerSelectionError]：连接超时

Question

更新2

我面临另一个错误，如果我按如下方式使用path，我将得到“无效的卷规范”错误，甚至将路径更改为"C:/docker-entrypoint-initdb.d/"，则init-mongo.sh将不会被执行，然后我将得到"UserNotFound:未能找到用户"xxxx“表示db”"admin“。

    volumes:
      - ./init-mongo/:/docker-entrypoint-initdb.d/
      - dbdata:/data/db

所以我切换到linux容器，所有的错误消息都消失了。

更新

在本地主机上禁用mongodb服务后，我已经解决了问题

net stop MongoDB

并使用端口27017

mongodb:
....
    ports:
      - "27017:27017"
.....

但是我想知道为什么我不能把端口27017换给别人呢？我更改端口是因为如果mongodb在我的计算机上运行(使用27017端口)，我将收到以下错误消息，谢谢。

for mongodb  Cannot start service mongodb: failed to create endpoint mongodb on network server_app_network: hnsCall failed in Win32: The process cannot access the file because it is being used by another process. (0x20)

原始

我在windows 10上使用了码头窗口容器，经过两天的挣扎，我仍然无法成功地部署我的项目。我的配置如下，谢谢您的帮助。

server.js

const dbUrl = "mongodb://mongodb:27018/";
mongoose
  .connect(`${dbUrl}mydb`, { useUnifiedTopology: true, useNewUrlParser: true })
  .then(res => {
    db = mongoose.connection;
    app.listen(port, () => {
      console.log(`listening on port ${port}`);
    });
  })
  .catch(error => console.log(error));

docker-compose.yml

  express-server:
    build:
      context: .
      dockerfile: Dockerfile
    image: express-server

    restart: unless-stopped
    ports:
      - "3000:3000"
    links:
      - mongodb
    depends_on: 
      - mongodb
    networks:
      - app_network

运行码头后-组合-构建-d

我认为您需要在配置上通过dbName。

mongoose.connect(
    connectionString,
    {
      useNewUrlParser: true,
      useUnifiedTopology: true,
      useFindAndModify: false,
      useCreateIndex: true,
      dbName: 'database-name', // IMPORTANT TO HAVE IT HERE AND NOT IN CONNECTION STRING
    },
    err => { throw err; },
  );
