Installing Docker on Windows
============================

Docker can run on Windows using a VM like VirtualBox. You then run
Linux within the VM.

Installation
------------

.. include:: install_header.inc

.. include:: install_unofficial.inc

1. Install virtualbox from https://www.virtualbox.org - or follow this tutorial__

.. __: http://www.slideshare.net/julienbarbier42/install-virtualbox-on-windows-7

2. Install vagrant from http://www.vagrantup.com - or follow this tutorial__

.. __: http://www.slideshare.net/julienbarbier42/install-vagrant-on-windows-7

3. Install git with ssh from http://git-scm.com/downloads - or follow this tutorial__

.. __: http://www.slideshare.net/julienbarbier42/install-git-with-ssh-on-windows-7


We recommend having at least 2Gb of free disk space and 2Gb of RAM (or more).

Opening a command prompt
------------------------

First open a cmd prompt. Press Windows key and then press “R”
key. This will open the RUN dialog box for you. Type “cmd” and press
Enter. Or you can click on Start, type “cmd” in the “Search programs
and files” field, and click on cmd.exe.

   :align: center

This should open a cmd prompt window.

   :alt: run docker
   :align: center

Alternatively, you can also use a Cygwin terminal, or Git Bash (or any
other command line program you are usually using). The next steps
would be the same.

.. _launch_ubuntu:

Launch an Ubuntu virtual server
-------------------------------

Let’s download and run an Ubuntu image with docker binaries already
installed.

.. code-block:: bash

	git clone https://github.com/dotcloud/docker.git 
	cd docker
	vagrant up

.. image:: images/win/run_02_.gif
   :alt: run docker
   :align: center

Congratulations! You are running an Ubuntu server with docker
installed on it. You do not see it though, because it is running in
the background.

Log onto your Ubuntu server
---------------------------

Let’s log into your Ubuntu server now. To do so you have two choices:

- Use Vagrant on Windows command prompt OR
- Use SSH

Using Vagrant on Windows Command Prompt
```````````````````````````````````````

Run the following command

.. code-block:: bash

	vagrant ssh

You may see an error message starting with “`ssh` executable not
found”. In this case it means that you do not have SSH in your
PATH. If you do not have SSH in your PATH you can set it up with the
“set” command. For instance, if your ssh.exe is in the folder named
“C:\Program Files (x86)\Git\bin”, then you can run the following
command:

.. code-block:: bash

	set PATH=%PATH%;C:\Program Files (x86)\Git\bin

.. image:: images/win/run_03.gif
   :alt: run docker
   :align: center

Using SSH
`````````

First step is to get the IP and port of your Ubuntu server. Simply run:

.. code-block:: bash

	vagrant ssh-config 

You should see an output with HostName and Port information. In this
example, HostName is 127.0.0.1 and port is 2222. And the User is
“vagrant”. The password is not shown, but it is also “vagrant”.

.. image:: images/win/ssh-config.gif
   :alt: run docker
   :align: center

You can now use this information for connecting via SSH to your
server. To do so you can:

- Use putty.exe OR
- Use SSH from a terminal

Use putty.exe
'''''''''''''

You can download putty.exe from this page
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html Launch
putty.exe and simply enter the information you got from last step.

.. image:: images/win/putty.gif
   :alt: run docker
   :align: center

Open, and enter user = vagrant and password = vagrant.

.. image:: images/win/putty_2.gif
   :alt: run docker
   :align: center

SSH from a terminal
'''''''''''''''''''

You can also run this command on your favorite terminal (windows
prompt, cygwin, git-bash, …). Make sure to adapt the IP and port from
what you got from the vagrant ssh-config command.

.. code-block:: bash

	ssh vagrant@127.0.0.1 –p 2222

Enter user = vagrant and password = vagrant.

.. image:: images/win/cygwin.gif
   :alt: run docker
   :align: center

Congratulations, you are now logged onto your Ubuntu Server, running
on top of your Windows machine !

Running Docker
--------------

First you have to be root in order to run docker. Simply run the
following command:

.. code-block:: bash

	sudo su

You are now ready for the docker’s “hello world” example. Run

.. code-block:: bash

	docker run busybox echo hello world

.. image:: images/win/run_04.gif
   :alt: run docker
   :align: center

All done!

Now you can continue with the :ref:`hello_world` example.

Troubleshooting
---------------

VM does not boot
````````````````

.. image:: images/win/ts_go_bios.JPG

If you run into this error message "The VM failed to remain in the
'running' state while attempting to boot", please check that your
computer has virtualization technology available and activated by
going to the BIOS. Here's an example for an HP computer (System
configuration / Device configuration)

.. image:: images/win/hp_bios_vm.JPG

On some machines the BIOS menu can only be accessed before startup.
To access BIOS in this scenario you should restart your computer and 
press ESC/Enter when prompted to access the boot and BIOS controls. Typically
the option to allow virtualization is contained within the BIOS/Security menu.

Docker is not installed
```````````````````````

.. image:: images/win/ts_no_docker.JPG

If you run into this error message "The program 'docker' is currently
not installed", try deleting the docker folder and restart from
:ref:`launch_ubuntu`
