Chef Local Development Workflow with ChefDK, Vagrant, VirtualBox, and Test Kitchen

Overview

The following document is intended to be a quick guide to getting you setup for doing local development with Chef. This guide was created on my MacBook, but should work fine with Linux, and Windows workstations as well.

Quick review on fundamental tenets of Chef

Workstation - A workstation is a computer that is configured to run various Chef command-line tools that synchronize with a chef-repo, author cookbooks, interact with the Chef server, interact with nodes, or applications like Chef Delivery
Node - A node is any machine—physical, virtual, cloud, network device, etc.—that is under management by Chef.
Chef Server- The Chef server acts as a hub for configuration data. The Chef server stores cookbooks, the policies that are applied to nodes, and metadata that describes each registered

This is an example of a collapsible drag and drop tree implementing slightly modified code from https://gist.github.com/robschmuecker/7880033

This is posted in order to demonstrate a viable answer for a Stack Overflow question http://stackoverflow.com/questions/20539922/has-anyone-produced-a-virtualised-javascript-tree-for-thousands-of-nodes

The only difference between this gist and the one referenced above is that the JSON file has changed. Each node contains 15 children and the depth is 4. Hence over 50,000 nodes.

The performance is fine if not too many of the nodes are present at once in the DOM. The JSON was contructed at http://www.json-generator.com/ with the following markup

What are the Kubernetes certifications?

There are four Kubernetes certifications:

	# This works
	curl -u USER:PASS https://api.github.com/repos/USER/REPO/contents/a.txt --request PUT --data-ascii $'{"path": "a.txt", "content": "bXkgbmV3IGZpbGUgY29udGVudHM=", "message": "hello"}'

	# Does not work
	curl -u USER:PASS https://api.github.com/repos/USER/REPO/contents/a.txt --request PUT --data-ascii $'{"path": "a.txt", "content": "", "message": "hello"}'
