This is part three of a four part series on attempting to automate installation and setup of a development PC with a few scripts and some funky tools. If you haven’t already, why not read the introductory post about ninite or even the second part about the command line version of WebPI? Disclaimer: this series was inspired by a blog from Maarten Balliauw.

Installing.. uh.. everything..: Chocolatey

Chocolatey is sort of “apt-get for windows” using powershell; it doesn’t quite achieve that yet, but the idea is the same; imagine nuget + apt-get. It works exactly like nuget but is meant to install applications instead of development components. The next release will support webpi from within chocolatey, but more on that in a moment.

There’s not much to look at yet, but that’s the point; you just type what you want and it’ll find and install it and any dependencies. I want to install virtualclonedrive, some sysinternals goodies, msysgit, fiddler, and tortoisesvn.

Before you start, make sure you’ve relaxed Powershell’s execution policy to allow remote scripts:
[powershell]Set-ExecutionPolicy Unrestricted[/powershell]

Ok, now we can get on with it. I can now execute a new powershell script to install choc and those apps:

[powershell]# Chocolatey
iex ((new-object net.webclient).DownloadString(‘http://bit.ly/psChocInstall’))

# install applications
cinst virtualclonedrive
cinst sysinternals
cinst msysgit
cinst fiddler
cinst tortoisesvn[/powershell]

This script will download (DownloadString) and execute (iex) the chocolatey install script from the bit.ly URL, which is just a powershell script living in github:
https://raw.github.com/chocolatey/chocolatey/master/chocolateyInstall/InstallChocolatey.ps1

This powershell script currently resolves the location of the chocolatey nuget package:
http://chocolatey.org/packages/chocolatey/DownloadPackage

Then, since a nupkg is basically a zip file, the chocolatey script unzips it to your temp dir and fires off chocolateyInstall.ps1; this registers all of the powershell modules that make up chocolatey. The chocolatey client is essentially a collection of clever powershell scripts that wrap nuget!

Once chocolatey is installed, the above script will fire off “cinst” – an alias for “chocolatey install” – to install each listed application.

What’s even more awesome is that the latest – not yet on the “master” branch – version of Chocolatey can install using webpi. To get this beta version, use the extremely terse and useful command from Mr Chocolatey himself, Rob Reynolds (@ferventcoder):

@rposbo git clone git://github.com/chocolatey/chocolatey.git | cd chocolatey | build | cd _{tab}| cinst chocolatey -source %cd%

Adding in the install of this beta version allows me to use choc for a few more webpi components:

[powershell]# Chocolatey
iex ((new-object net.webclient).DownloadString(‘http://bit.ly/psChocInstall’))

# install applications
cinst virtualclonedrive
cinst sysinternals
cinst msysgit
cinst fiddler
cinst tortoisesvn

# getting the latest build for webpi support: git clone git://github.com/chocolatey/chocolatey.git | cd chocolatey | build | cd _{tab}| cinst chocolatey -source %cd%
# I’ve already done this and the resulting nugetpkg is also saved in the same network directory:
cinst chocolatey –source “Z:\Installation\SetupDevPC\”

# Now I’ve got choc I may as well use it to install a bunch of other stuff from WebPI;
# things that didn’t always work when I put them in the looong list of comma delimited installs
# IIS
cinst IIS7 -source webpi
cinst ASPNET -source webpi
cinst BasicAuthentication -source webpi
cinst DefaultDocument -source webpi
cinst DigestAuthentication -source webpi
cinst DirectoryBrowse -source webpi
cinst HTTPErrors -source webpi
cinst HTTPLogging -source webpi
cinst HTTPRedirection -source webpi
cinst IIS7_ExtensionLessURLs -source webpi
cinst IISManagementConsole -source webpi
cinst IPSecurity -source webpi
cinst ISAPIExtensions -source webpi
cinst ISAPIFilters -source webpi
cinst LoggingTools -source webpi
cinst MetabaseAndIIS6Compatibility -source webpi
cinst NETExtensibility -source webpi
cinst RequestFiltering -source webpi
cinst RequestMonitor -source webpi
cinst StaticContent -source webpi
cinst StaticContentCompression -source webpi
cinst Tracing -source webpi
cinst WindowsAuthentication -source webpi[/powershell]

Best bit about this? When you run the first command you’ll download and install the latest version of the specified executable. When this succeeds you’ll get:

[code] has finished successfully! The chocolatey gods have answered your request![/code]

Nice.

You’ll hopefully see your Powershell window update like this a few times:
(click to embiggen)

But depending on your OS version (I’m using Windows Server 2008 R2) you might see a few alerts about the unsigned drivers you’re installing:

That doesn’t seem to be avoidable, so just click to install and continue.

You might also find that your own attempts to install the beta version of chocolatey fail with errors like these:

or
(click to embiggen)

This is due to how you reference the directory in which your beta choc nuget package lives. If you reference it from a root dir (e.g. “Z:\”) then it’ll fail. Put it in a subdirectory and you’re golden:

or using “%cd%” as the source dir (assuming you’re already in that dir):

So, with my new powershell script and the beta chocolatey nupkg, along with the existing script for ninite, webpi and their components, my PC Setup directory now looks like this:

The last part of this series focuses on installing other things that either can’t be done or just didn’t work using one of the previous options, a list of “interesting things encountered”, and a conclusion to the whole project; see you back in:

Scripting the setup of a developer PC, Part 4 of 4 – Installing Custom Stuff, Interesting Things Encountered, and Conclusion.

Update: The chocolatey “beta” I mentioned is actually now in the mainline.
