Supported built-in functions

abs(float) - Returns the absolute value of a given float. Example: abs(1) returns 1, and abs(-1) would also return 1, whereas abs(-3.14) would return 3.14. See also the signum function.
basename(path) - Returns the last element of a path.
base64decode(string) - Given a base64-encoded string, decodes it and returns the original string.

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

Prerequisites

This has been moved into the official Chef docs:

12.5 style custom resources

This is by far the most recommended way of writing resources for all users. There are two gotchas which we're working through:

For helper functions that you used to write in your provider code or used to mixin to your provider code, you have to use an action_class do ... end block.

Install Python 3.7.x from https://www.python.org/downloads/ or via homebrew.

$ brew install python3   # Installed at /usr/local/Cellar/python3

Check that python3 has been installed by running it at the terminal:

$ python3
>>> Python 3.7.2

Download get-pip.py from https://bootstrap.pypa.io/get-pip.py and install (this should already be installed if python was installed from python.org or homebrew):

ChefDK, Test Kitchen Driven NTP Cookbook

This gist uses TK+Berkshelf to drive creating a vagrant virts and converging a simple recipe to install and configure NTPd. This is a simple cookbook that has one recipe, one template (for ntp.conf) and one attribute file. It works on Ubuntu 12.04 and CentOS 6.4 (and derviatives) and the attribute file is used to support both distros.

This should work on Mac (where I developed it) and any chef-supported Linux that you can get Vagrant onto (Ubuntu/CentOS).

Because I use ChefDK and Test Kitchen, I can largely ignore setting up Vagrant and Berkshelf and can get right to work on writing recipe code.
