Did you know that every time the chef-client runs, it knows what time it is, and it stores that value as a node attribute, ohai_time? Did you know that you can use this value for searching a Chef Infra Server? It's a Unix Epoch!

For example, let's look for the nodes that were updated in the last 10-15 minutes:

now=$(date +%s)
range_start=$(expr $now - 900)
range_end=$(expr $now - 600)

knife search node "ohai_time:[$range_start TO $range_end]" -a ohai_time -F json

Prerequisites

You'll need to have a system running that is accessible through a DNS record. It should have access to the public Habitat depot, https://app.habitat.sh so it can download the required packages.

You'll need to register an OAuth application for GitHub. You need the client ID and client secret that are created for the application later in this guide. Your system needs to have access to https://github.com so that it can authenticate.

Your system also needs to have an FQDN that can be resolved, for example depot.example.com. This will be used in your OAuth application's "Authorization Callback URL." For this example, use http://depot.example.com/#/sign-in. The /#/sign-in is required.

Most of the recipes are just from the Opscode cookbooks. Exceptions or differences:

• ruby19 is a recipe that just installs ruby1.9.1-full, nothing fancy. Use Fletcher Nichol's rbenv or rvm cookbooks for those if you prefer.
• emacs24 recipe is one that I used to install Emacs 24 from a PPA before it was officially released. The actual recipe is attached to this gist, just put it in a cookbook named emacs24 as the default recipe.
• users recipe is one that just manages the dotfiles for my user, it's based on a really old version of Opscode's users cookbook.

# Config for Nginx to act as a front-end for Riak
# The main goal is to proxy all GETs directly to Riak, and disallow anything else (POST, PUT, etc)
# Also, disallow use of the map/reduce query links (i.e. /riak/bucket/key/_,_,_)

# Config is in /etc/nginx/sites-available/default or somewhere like that

# Set up load-balancing to send requests to all nodes in the Riak cluster
# Replace these IPs/ports with the locations of your Riak nodes
