Deploy mongodb in docker, and the data files are persisted to mac (my local machine). The test found that as long as the data file directory is placed in docker, there will be no problem. Once the file is placed, it is mounted through the docker -v command The following error pops up in the folder that comes over:
docker startup command:
docker run -it -v /Usr/happyhour7/code/data:/data mongodb /bin/bash

Are you running Docker directly on your MacBook? The official documentation about Volume says this:
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.
It means you need to configure Docker before you can use Volume
