Chef Diff

Intro

Chef Diff is a library for calculating what Chef objects where modified between two revisions in Chef Git repo. Chef Diff is a derivative/extension of Between Meals.

Chef Diff calculates changes for nodes, clients, users, environments, databags, roles and cookbooks between revisions in a Chef repo.

Chef Diff allows subdirs in nodes, clients and environments to enable the Chef repo layout to match a clustered multi Chef server infrastructure.

Usage

Cheff Diff is mainly intended to be used as a gem by other tools but provides a commandline inspection tool:

$ chef-diff
Usage: chef-diff [options] <repo_path>
    -v, --verbose                    Run verbosely
    -s, --start_ref REF              Git start reference
    -e, --end_ref REF                Git end reference (default HEAD)
