Commented knife.rb for all the things
# Knife Configuration File.
#
# This is a Ruby DSL to set configuration parameters for Knife's
# general options. The default location for this file is
# ~/.chef/knife.rb. If multiple Chef repositories are used,
# per-repository configuration files can be created. A per repository
# configuration file must be .chef/knife.rb in the base directory of
# the Chef repository. For example,
#
# ~/Development/chef-repo/.chef/knife.rb

Spechal / 1_kubernetes_on_macOS.md
Created August 6, 2018 20:57 — forked from kevin-smets/1_kubernetes_on_macOS.md
Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

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!

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.

NOTE: Modern (7/6/2014) Recipe Generation
