How to setup your VMWare Fusion images to use static IP addresses on Mac OS X

At Crush + Lovely, we use Railsmachine's Moonshine to automate the configuration of our servers. When writing our deployment recipes, VMWare Fusion's ability to take snapshots and rollback to these snapshots is a huge timesaver because it takes just seconds to roll a server image to it's original state.

When you're just configuring a single server, having a static IP address for your server image isn't too important, but when you're configuring multi-server setups, it can be useful to duplicate a number of server images and give each a static IP address so you can consistently deploy to them. While not documented well at all, it turns out that this is relatively easy to accomplish in four simple steps.

1. Determine the MAC address of your guest machine

Let's say you have a guest machine with the name ubuntu-lucid-lynx-base a

Setting up a local DNS server with bind on OSX Mavericks

This is really just an approach for locally testing DNS changes, which can easily be done with a HOSTS file if the change involves an IP address, but gets a bit trickier when things like CNAMEs are involved. This is only meant to test locally off a single machine.

1. Install bind using homebrew

   brew install bind

2. Follow the installation steps to start up bind

Requirements:

• Raspberry Pi (I used the B+ model)
• Enough hard drive space for install media (I mounted a 16 GB USB3 drive at /var/www/cobbler/)

Installation

The problem with installing cobbler on a Raspberry Pi, is that it depends on the syslinux package, which is not available for ARM architectures. More importantly, we specifically need the x86 version of syslinux anyway, because it provides the files that will be used to PXE boot systems (which in my case is x86_64 arch).
