boot2docker为什么能操作到物理机

Question

Answer 1

Docker is installed in the virtual machine
Then it goes like this:
The directory of the host is mounted to the virtual machine,
Then the docker of the virtual machine uses volume to map the directory to the docker container

Answer 2

The principle of boot2docker is to install a streamlined version of Linux virtual machine. The management method and command parameters look very similar to vagrant. I don’t know if it is packaged vagrant. By default, the home directory of the host is mounted to the virtual machine.
