Windows Templates for Packer

Introduction

This repository contains Windows templates that can be used to create boxes for Vagrant using Packer (Website) (Github).

This repo began by borrowing bits from the VeeWee Windows templates (https://github.com/jedi4ever/veewee/tree/master/templates). Modifications were made to work with Packer and the VMware Fusion / VirtualBox providers for Packer and Vagrant.

Packer Version

Packer 0.5.1 or greater is required.

Windows Versions

The following Windows versions are known to work (built with VMware Fusion 6.0.4 and VirtualBox 4.3.12):

Windows 2012 R2
Windows 2012 R2 Core
Windows 2012
Windows 2008 R2
Windows 2008 R2 Core
Windows 10
Windows 8.1
Windows 7

Windows Editions

All Windows Server versions are defaulted to the Server Standard edition. You can modify this by editing the Autounattend.xml file, changing the ImageInstall>OSImage>InstallFrom>MetaData>Value element (e.g. to Windows Server 2012 R2 SERVERDATACENTER).

Product Keys

The Autounattend.xml files are configured to work correctly with trial ISOs (which will be downloaded and cached for you the first time you perform a packer build). If you would like to use retail or volume license ISOs, you need to update the UserData>ProductKey element as follows:

Uncomment the <Key>...</Key> element
Insert your product key into the Key element

If you are going to configure your VM as a KMS client, you can use the product keys at http://technet.microsoft.com/en-us/library/jj612867.aspx. These are the default values used in the Key element.

Windows Updates

The scripts in this repo will install all Windows updates – by default – during Windows Setup. This is a very time consuming process, depending on the age of the OS and the quantity of updates released since the last service pack. You might want to do yourself a favor during development and disable this functionality, by commenting out the WITH WINDOWS UPDATES section and uncommenting the WITHOUT WINDOWS UPDATES section in Autounattend.xml:

<!-- WITHOUT WINDOWS UPDATES -->
<SynchronousCommand wcm:action="add">
    <CommandLine>cmd.exe /c C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -File a:\openssh.ps1 -AutoStart</CommandLine>
    <Description>Install OpenSSH</Description>
    <Order>99</Order>
    <RequiresUserInput>true</RequiresUserInput>
</SynchronousCommand>
<!-- END WITHOUT WINDOWS UPDATES -->
<!-- WITH WINDOWS UPDATES -->
<!--
<SynchronousCommand wcm:action="add">
    <CommandLine>cmd.exe /c a:\microsoft-updates.bat</CommandLine>
    <Order>98</Order>
    <Description>Enable Microsoft Updates</Description>
</SynchronousCommand>
<SynchronousCommand wcm:action="add">
    <CommandLine>cmd.exe /c C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -File a:\openssh.ps1</CommandLine>
    <Description>Install OpenSSH</Description>
    <Order>99</Order>
    <RequiresUserInput>true</RequiresUserInput>
</SynchronousCommand>
<SynchronousCommand wcm:action="add">
    <CommandLine>cmd.exe /c C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -File a:\win-updates.ps1</CommandLine>
    <Description>Install Windows Updates</Description>
    <Order>100</Order>
    <RequiresUserInput>true</RequiresUserInput>
</SynchronousCommand>
-->
<!-- END WITH WINDOWS UPDATES -->

Doing so will give you hours back in your day, which is a good thing.

OpenSSH / WinRM

Currently, Packer has a single communicator that uses SSH. This means we need an SSH server installed on Windows - which is not optimal as we could use WinRM to communicate with the Windows VM. In the short term, everything works well with SSH; in the medium term, work is underway on a WinRM communicator for Packer.

If you have serious objections to OpenSSH being installed, you can always add another stage to your build pipeline:

Build a base box using Packer
Create a Vagrantfile, use the base box from Packer, connect to the VM via WinRM (using the vagrant-windows plugin) and disable the 'sshd' service or uninstall OpenSSH completely
Perform a Vagrant run and output a .box file

It's worth mentioning that many Chef cookbooks will not work properly through Cygwin's SSH environment on Windows. Specifically, packages that need access to environment-specific configurations such as the PATH variable, will fail. This includes packages that use the Windows installer, msiexec.exe.

It's currently recommended that you add a second step to your pipeline and use Vagrant to install your packages through Chef.

Using .box Files With Vagrant

The generated box files include a Vagrantfile template that is suitable for use with Vagrant 1.6.2+, which includes native support for Windows and uses WinRM to communicate with the box.

Getting Started

Trial versions of Windows 2008 R2 / 2012 / 2012 R2 / 2016 are used by default. These images can be used for 180 days without activation.

Alternatively – if you have access to MSDN or TechNet – you can download retail or volume license ISO images and place them in the iso directory. If you do, you should supply appropriate values for iso_url (e.g. ./iso/<path to your iso>.iso) and iso_checksum (e.g. <the md5 of your iso>) to the Packer command. For example, to use the Windows 2008 R2 (With SP1) retail ISO:

Download the Windows Server 2008 R2 with Service Pack 1 (x64) - DVD (English) ISO (en_windows_server_2008_r2_with_sp1_x64_dvd_617601.iso)
Verify that en_windows_server_2008_r2_with_sp1_x64_dvd_617601.iso has an MD5 hash of 8dcde01d0da526100869e2457aafb7ca (Microsoft lists a SHA1 hash of d3fd7bf85ee1d5bdd72de5b2c69a7b470733cd0a, which is equivalent)
Clone this repo to a local directory
Move en_windows_server_2008_r2_with_sp1_x64_dvd_617601.iso to the iso directory

Run:

packer build \
    -var iso_url=./iso/en_windows_server_2008_r2_with_sp1_x64_dvd_617601.iso \
    -var iso_checksum=8dcde01d0da526100869e2457aafb7ca windows_2008_r2.json

Variables

The Packer templates support the following variables:

Name	Description
`iso_url`	Path or URL to ISO file
`iso_checksum`	Checksum (see also `iso_checksum_type`) of the ISO file
`iso_checksum_type`	The checksum algorithm to use (out of those supported by Packer)
`autounattend`	Path to the Autounattend.xml file
