mongodb - Docker mongodb 与 mac os x 共享卷

Question

我尝试在 mac 终端中使用以下命令在 mac os x 10.10.2 上使用 mongodb 官方 docker 镜像:

docker run -v /Users/john/data/db:/data/db -p 27017:27017 mongo --smallfiles

但它退出并显示此错误日志:

我不明白的是，如果我在 docker-machine 中执行相同的命令，并将相同的数据放在 docker-machine 文件夹中，那么一切正常。

我已经尝试在文件夹上 chmod -R 777 但它不能解决问题。

有人可以解释我在这里做错了什么吗？

我们可以将数据放在安装在 docker-machine 中的“/Users”文件夹中，以便与 mac os x 上的容器共享吗？

mongodb 是否需要有关文件系统的特定信息？

好像是特定于mongo软件和virtualbox的使用，见mongo docker README .

WARNING (Windows & OS X): The default Docker setup on Windows and OS X uses a VirtualBox VM to host the Docker daemon. Unfortunately, the mechanism VirtualBox uses to share folders between the host system and the Docker container is not compatible with the memory mapped files used by MongoDB (see vbox bug, docs.mongodb.org and related jira.mongodb.org bug). This means that it is not possible to run a MongoDB container with the data directory mapped to the host.

如果你将 datadir 放在挂载的卷之外，它的行为就不是这样了。
