问题描述
在docker中部署mongodb，数据文件持久化到mac（我本机）中，测试发现，只要将数据文件目录放到docker中就没问题，一旦将文件放到通过docker -v命令挂载过来的文件夹中就回爆出如下错误：
docker启动命令：
docker run -it -v /Usr/happyhour7/code/data:/data mongodb /bin/bash

问题解答
回答1：你是直接在MacBook上运行Docker吧？关于Volume官方文档是这样说的:
File sharing
You can decide which directories on your Mac to share with containers.
Add a Directory - Click + and navigate to the directory you want to add.
Click Apply & Restart to make the directory available to containers using Docker’s bind mount (-v) feature.
意思是你需要先配置Docker，然后才能使用Volume
