Description

Ohai detects data about your operating system. It can be used standalone, but its primary purpose is to provide node data to Chef.

Ohai will print out a JSON data blob for all the known data about your system. When used with Chef, that data is reported back via node attributes.

Chef distributes ohai as a RubyGem. This README is for developers who want to modify the Ohai source code. For users who want to write plugins for Ohai, see the docs:

Development Environment

Ohai's development dependencies should be installed with bundler. Just run bundle install in the root of the repo.

Spec Testing

We use RSpec for unit/spec tests. To run the full suite, run:

bundle exec rake spec

You can run individual test files by running the rspec executable:

bundle exec rspec spec/unit/FILE.rb

Style

We use Cookstyle, as a code linter, to enforce style guidelines. To run:

bundle exec rake style

You can run and automatically correct the issues:

bundle exec rake style:auto_correct

Rake Tasks

Ohai has some Rake tasks for doing various things.

bundle exec rake -T
rake build               # Build ohai-$VERSION.gem into the pkg directory
rake clean               # Remove any temporary products
rake clobber             # Remove any generated files
rake install             # Build and install ohai-$VERSION.gem into system gems
rake install:local       # Build and install ohai-$VERSION.gem into system gems without network access
rake release[remote]     # Create tag $VERSION and build and push ohai-$VERSION.gem to rubygems.org
rake spec                # Run RSpec code examples
rake style               # Run Chefstyle tests
rake style:auto_correct  # Auto-correct RuboCop offenses

($VERSION is the current version, from the GemSpec in Rakefile)
