Problems Using Docker on Windows 7

1. Customizing the docker-machine Location

When using Docker on Windows 7, docker-machine is stored by default in the C:\users\your name\.docker\machine\machines directory.

To avoid taking up storage space on the system drive, you can change this as follows.

If you have not created a virtual machine yet, you can specify the location by setting the MACHINE_STORAGE_PATH environment variable.

Then run Docker Quickstart Terminal to create and run docker-machine.

If you have already created a virtual machine, you need to migrate the virtual machine and then restart docker-machine.

2. Directory Mounting

On Windows 7, Docker runs inside the virtual environment provided by VirtualBox. Mounting a directory involves file sharing between three parties:

Windows
The virtual machine in VirtualBox
Docker

Mounting a folder from Windows 7 into Docker goes through the virtual machine and takes two steps:

Step one: mount the Windows folder into the virtual machine in VirtualBox

As shown above, open VirtualBox and find a virtual machine named default — this virtual machine is the Docker host. Create a shared folder in it, for example mounting D:\ to the /d directory.

Then restart the virtual machine.

1
docker-machine restart

Step two: mount the virtual machine’s directory in VirtualBox into Docker

Mount the /d/data directory in the virtual machine to the container’s /data directory

1
docker run -it -v /d/data:/data centos /bin/bash

3. Configuring a Registry Mirror

Log into the virtual machine in SSH mode

1
docker-machine ssh default

Edit the configuration and add the mirror

sudo vi /var/lib/boot2docker/profile
EXTRA_ARGS='
--label provider=virtualbox
--registry-mirror=http://f1361db2.m.daocloud.io

Restart the virtual machine

1
docker-machine restart
