Is it possible to mount my existing Mongo DataBase with docker-compose?

问题

在经过几个月的开发后，我发现将我的MERN应用程序容器化是更好的选择。我成功创建了一个**.yaml文件，一切都正常工作，但问题是我已经有了大量已收集的数据。我想要能够将这些数据挂载到容器中，但我不知道如何操作。我阅读了很多资料，但在组合应用程序后，我的数据仍然没有出现。以下是我的docker-compose.yaml**文件的外观：

  1. version: '3.9'
  3. services:
  4.   # MongoDB 服务
  5.   mongo_db:
  6.     container_name: db_container
  7.     image: mongo:latest
  8.     restart: always
  9.     ports:
  10.       - 2717:27017
  11.     volumes:
  12.       - /mnt/c/temp/mongo/db:/data/db
  14.   # Node API 服务
  15.   api:
  16.     build: .
  17.     ports:
  18.       - 4001:4001
  19.     environment:
  20.       PORT: 4001
  21.       MONGODB_URI: mongodb://db_container:27017
  22.       DB_NAME: project-system
  23.     depends_on:
  24.       - mongo_db
  26. volumes:
  27.   mongo_db:

正如您在以下行中所看到的：

  1. volumes:
  2.   - /mnt/c/temp/mongo/db:/data/db

我试图指定来自我的C:\驱动器的路径，但这不起作用。我还尝试将相同的行放在：

  1. volumes:
  2.   mongo_db:

（文件底部），但同样没有成功。基本上，我的现有数据库位于

C:\data\db

如何将其指定为MongoDB服务的源呢？

After some months of development I got to a point where it is better to dockerize my MERN application. I managed to create .yaml file and everything is working OK but the problem is that I already have big amount of data that is collected. I want to be able to mount this data to container but I don't know how to do it. Read a lot of stuff but still my data is not appearing after composing the applications. Here is how my docker-compose.yaml file looks-like:

  1. version: '3.9'
  3. services:
  4.   #MongoDB Service
  5.   mongo_db:
  6.     container_name: db_container
  7.     image: mongo:latest
  8.     restart: always
  9.     ports:
  10.       - 2717:27017
  11.     volumes: 
  12.       - /mnt/c/temp/mongo/db:/data/db 
  14.   #Node API Service
  15.   api:
  16.     build: .
  17.     ports: 
  18.      - 4001:4001
  19.     environment:
  20.       PORT: 4001
  21.       MONGODB_URI: mongodb://db_container:27017
  22.       DB_NAME: project-system
  23.     depends_on:
  24.       - mongo_db
  25.   
  26. volumes:
  27.   mongo_db:

As you can see in this row:

  1.   volumes: 
  2.       - /mnt/c/temp/mongo/db:/data/db

I am trying to point the path from my C:\ drive but this doesn't work. I also tried the same row in:

  1. volumes:
  2.   mongo_db:

(the bottom of file) but again without success. Basically my existing DB is on

> C:\data\db

How can I point this to be the source of MongoDB service?

First, you need to create the dump from local MongoDB and copy those files to docker MongoDB. You can use these commands to create:

  1. mongodump --uri 'mongodb://localhost:27017/yourdatabase' --archive=<your file> --gzip
  2. mongorestore --uri 'mongodb://remotehost:27017/yourdatabase' --archive=<your file> --gzip

You should be able to access the docker from local host.

Note: Reference this answer if you don't get it correct.

You can do these changes on the path you are mounting to make data persistent. Create a new folder C:/data/docker_mongo to make data persistent.

  1. version: '3.9'
  3. services:
  4.   #MongoDB Service
  5.   mongo_db:
  6.     container_name: db_container
  7.     image: mongo:latest
  8.     restart: always
  9.     ports:
  10.       - 2717:27017
  11.     volumes: 
  12.       - C:/data/docker_mongo:/data/db 
  14.   #Node API Service
  15.   api:
  16.     build: .
  17.     ports: 
  18.      - 4001:4001
  19.     environment:
  20.       PORT: 4001
  21.       MONGODB_URI: mongodb://db_container:27017
  22.       DB_NAME: project-system
  23.     depends_on:
  24.       - mongo_db
  25.   
  26. volumes:
  27.   mongo_db:
