Auto-enable Local HTTP Caching in Test Kitchen

README.md

Auto-enable Local HTTP Caching in Test Kitchen

Note: total experiment and hack, looks nasty, could be awesome:

Setup

  • Drop the kitchen.local.yml into $HOME/.kitchen/config.yml
  • Install polipo (with Mac: brew install polipo, with Ubuntu: apt-get install polipo)
  • Drop polipo-start and polipo-console somewhere useful (perhaps $HOME/bin?)

Run with HTTP Caching Proxy

Simply start up polipo in the foreground in a terminal/tmux/screen session with: ~/bin/polipo-start. In your Test Kitchen project verify that caching is enabled by running kitchen list --debug and look for the http_proxy and chef_omnibus_url config options.
