walk through all the cookbooks in the cookbooks directory and add a berksfile entry for each one at the path location. doesn't work so well on large repos.
Dir.glob(File.join(File.dirname(__FILE__), "cookbooks", "*")).each do |cb|
cookbook File.basename(cb), :path => cb

Poking at Supermarket and Berkshelf and self-signed certs

Notes

ssl testing

Even with ssl.verify off, berks install or berks vendor will fail when supermarket is using a self-signed certificate. So, how do we get around that?

Note: I hacked my /etc/hosts to resolve supermarket-0.c.cheffian-supermarket.internal

Get the CERT

Docker Container Stats Collection Using Collectd

Docker stats collection for collectd

This script can be used to feed collectd with cpu and memory usage statistics for running docker containers using the collectd exec plugin.

This script will report the used and cached memory as well as the user and system cpu usage by inspecting the appropriate cgroup stat file for each running container.

Usage

This script is intented to be executed by collectd on a host with running docker containers. To use, simply configure the exec plugin in collectd to execute the collectd-docker.sh script. You may need to adjust the script to match your particulars, such as the mount location for cgroup.
