我正在尝试为我公司的人员建立一个易于使用的工作流程，以便在 Windows 上设置 MongoDB 数据库，并使他们能够根据需要交换数据库。
这里的一个障碍是需要为此使用 Docker Volumes，这是目前我在导出和导入数据方面遇到的最大问题。
我的 docker-compose.yml 看起来像这样:
version: "3"
services:
mongoDB:
image: mongo:4.0.4
container_name: "mongo_database"
environment:
- MONGO_INITDB_DATABASE=test_database
- MONGO_INITDB_ROOT_USERNAME=root_username
- MONGO_INITDB_ROOT_PASSWORD=root_password
volumes:
- ./init-mongo.js:/docker-entrypoint-initdb.d/init-mongo.js:ro
- mongo_database_volume:/data/db
ports:
- "27017-27019:27017-27019"
volumes:
mongo_database_volume:
我已经能够使用以下命令在那里输入数据并成功导出我认为是数据库的内容:
docker cp mongo_database:/data/db ./_backup
这在 docker-compose.yml 旁边创建了一个文件夹“db_backup”，我认为其中的内容是编码的数据库内容。
然后我更改了一些数据，再次将其导出到不同的文件夹，并尝试使用我认为与上述命令相反的命令再次导入旧数据库:
docker cp "./db_backup" mongo_database:/data/db
我的期望是，此后更改的值将恢复为数据库中的原始值。
然而，遗憾的是，改变后的值仍然改变了。导入显然失败了。
因此，在将本地文件夹 db_backup 重命名为 db 后，我尝试了此操作:
Docker cp ./db mongo_database:/data/
它做了一些事情，即碎片化 MongoDB。容器立即崩溃，在尝试重新运行它后，我收到了以下令人兴奋的错误消息:

所以，很明显，我在这里做了一些非常错误的事情。我只是不知道出了什么问题。
谁能告诉我在 Windows 上从 Docker 容器导出/导入 MongoDB 数据库的正确方法是什么？我们的一个典型用例是选择不同的测试数据库，我们希望根据情况需要交换这些数据库。
最佳答案
这就是我最终设法开始工作的内容。这并不是我真正希望的，更多的是一种解决方法，但我想这总比没有好，也许这会对某些人有所帮助。
我最终使用 MongoDB Compass 来进行备份。如果容器配置正确，您可以使用 MongoDB Compass 从外部连接它，然后使用 MongoDB Compass 将数据库导出到文件，然后再导入。
关于Windows 版 Docker 上的 MongoDB ~ 导出/导入数据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59900225/
