问题
But I want to mount /d because I like to put my projects on /d.
回答1:
docker-machine uses a boot2docker.iso VM image, based on TinyCore
The original boot2docker project mentioned that you can mount other folders with, at runtime:
mount -t vboxsf -o uid=1000,gid=50 your-other-share-name /some/mount/location
Issue 1814 of docker-machine suggests that, and it seems to work.
