Docker - Installation for Windows 7 (Docker Toolbox)

About

How I have installed and configured Docker in my Windows 7 laptop. The software for windows 7 is called Docker Toolbox.

Steps

Install Toolbox (for version before Windows 10)

Before version Windows 10: Toolbox:

Toolbox Components:

• Docker CLI client for running Docker Engine to create images and containers
• Docker Machine so you can run Docker Engine commands from Windows terminals
• Docker Compose for running the docker-compose command
• Oracle VM VirtualBox
• Kitematic, the Docker GUI
• the Docker QuickStart shell preconfigured for a Docker command-line environment

Create an host

I don't remember if it's necessary.

• Create a machine with docker-machine named default in VirtualBox

docker-machine create ^
    --driver virtualbox ^
    --virtualbox-memory 8192 ^
    --virtualbox-disk-size "40960"  ^
    default

Environment

Variable

• Get the docker environment variable of your host that you get with docker-machine

docker-machine env

You can further specify your shell with either 'cmd' or 'powershell' with the --shell flag.

SET DOCKER_TLS_VERIFY=1
SET DOCKER_HOST=tcp://192.168.99.100:2376
SET DOCKER_CERT_PATH=C:\Users\gerard\.docker\machine\machines\default
SET DOCKER_MACHINE_NAME=default
SET COMPOSE_CONVERT_WINDOWS_PATHS=true
REM Run this command to configure your shell:
REM     @FOR /f "tokens=*" %i IN ('"C:\DockerToolbox\docker-machine.exe" env') DO @%i

• Create them:
  • Windows Key > Env > Env for your account

• Add the 4 env variables

Host

Add a docker host in your host file with the host ip

• Obtain the IP

docker-machine ip

192.168.99.100

• Open an editor as Adminsitrator and add it to the host file C:\Windows\System32\drivers\etc\hosts

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# ...........................
192.168.99.100   docker-host

SSH - Winscp

Create a new connection with the following parameters:

• the docker machine ip
• username: docker
• pwd: tcuser

You should be able to see the c and d drive:

Shared Drive

When mounting a volume with the bind method, your local drive must be made available to the host (in all case on Windows 7 with Toolbox). The steps are well explained also in the VirtualBox Doc on shared folder.

Without following this steps, you can get this kind of issue: Bind mount issue on Docker for Windows)

Step 0 - The default shared folder

By default, you will see already a shared drive with:

• the folder path \\?\c:\Users
• the name c/Users
• auto-mount checked
• Make permanent checked

It means that the path c:\\Users is already shared.

If you put your files under this directory, you are done. If not, you need to follow the below steps.

Step 1 - Create the shared folder in Virtual Box

• Manually create a Machine Folder share.

• or with a script

VBoxManage sharedfolder add "default" --name "c" --hostpath "C:\"
VBoxManage sharedfolder add "default" --name "d" --hostpath "D:\"

where:

• c is a name (not a path)
• automatic mount means that the folders are mounted into the /media directory, along with the prefix sf_ (No thanks).
• Access = Full means read and write.

Step 2 - Mount the shared folder in the docker host

• Log into the host with docker-machine

docker-machine ssh 
# docker-machine ssh machineName
sudo su -

• Create a file bootlocal.sh in your home and add the following line of code

# C
mkdir /c
mount -t vboxsf c /c

# D
mkdir /d
mount -t vboxsf d /d

• Execute it

chmod u+x o+x g+x bootlocal.sh 
cd /home/docker
./bootlocal.sh 

Step 3 - Make the mount automatic

• To mount a shared folder during boot, copy the file as root to the directory /var/lib/boot2docker/

sudo su -
cp /home/docker/bootlocal.sh /var/lib/boot2docker/
