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:
- General documentation: https://docs.chef.io/ohai.html
- Writing Ohai Plugins documentation: https://docs.chef.io/ohai_custom.html
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 Chefstyle, 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-$VERSION.gem into the pkg directory
rake clean # Remove any temporary products
rake clobber # Remove any generated files
rake docs # Generate YARD Documentation
rake install # Build and install ohai-$VERSION.gem into system gems
