There’s a rumor floating around that I automate everything on my laptop with Chef, including window maximizing. While that’s not entirely true, I do automate as much as possible on my workstations with Chef, as I have three laptops I use regularly. One application I like to have installed is VirtualBox, because I do some Chef recipe testing with it and Vagrant.
I did the most natural thing ever, I wrote a cookbook to automate installation of VirtualBox on OS X. The disk image file that Oracle distributes for VirtualBox on OSX uses an “mpkg” installer package, so I couldn’t just use the dmg_package LWRP I wrote to install it in /Applications. I extended the dmg_package provider to allow a type to be specified and pushed a new release of the dmg cookbook (v.0.6.0). The recipe in my cookbook builds the URL, which may seem convoluted (maybe it is), but it makes it more dynamic and customizable with fewer assumptions. The actual usage looks like this:
One thing to note about the mpkg type, is that these generally want to install in /Applications, which often requires root privileges. The dmg_package LWRP will use sudo when performing the mpkg installation, so if you’re like my and want to run chef-client as a non-root user for most things, it will prompt for your password, unless you unlock sudo in the same shell. Output of VirtualBox being installed:

After writing and testing, the next thing I wanted to do is share the cookbook on the Opscode Chef Community site. However, I discovered that the good Chris Peplin already shared one! Since the site has a flat namespace, I would have to name mine differently. However, I think it would be better to collaborate in true Open Source fashion with Chris, and we’ll collaborate on this.
