I face another error, if I use path as follows, I will get "invalid volume specification" error even change path to "C:/docker-entrypoint-initdb.d/", the init-mongo.sh will not be executed, then I get "UserNotFound: Could not find user "xxxx" for db "admin"

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

因此我切换到Linux容器，所有错误消息都消失了。

我在本地主机上禁用mongodb服务后解决了问题

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将端口27017更改为其他端口？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），我会得到下面的错误信息，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)

我正在Windows 10上使用Docker Windows容器。经过两天的努力，我仍然无法成功部署我的项目。我的配置如下，感谢帮助。
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

运行docker-composeup--build-d之后
