Knife plugin for Chef to draw dependency graphs for roles that have become spaghetti.
Ruby 1.9.2 and higher.
This plugin requires on Graphviz, and should be installed prior to installing the plugin.
Graphviz may be obtained through a variety of methods. On OSX an easy method is via Homebrew:
$ brew install graphviz
$ gem install knife-role-spaghetti
NOTE: Ensure that your knife.rb has the role_path setting configured.
Since this is a Knife plugin, execution should be performed in your Chef repository.
Execute:
$ knife role spaghetti
with no arguments should result in a new file named role-spaghetti.png in your
repo root.
$ knife role spaghetti "/tmp/someotherfilename.png"
will place the file in the specified location.
Execute knife role spaghetti -h for more options.
