This is a Heroku Buildpack for Ruby, Rack, and Rails apps. It uses Bundler for dependency management.
This buildpack requires 64-bit Linux.
$ ls Gemfile Gemfile.lock $ heroku create --buildpack heroku/ruby $ git push heroku main ... -----> Heroku receiving push -----> Fetching custom buildpack -----> Ruby app detected -----> Installing dependencies using Bundler version 1.1.rc Running: bundle install --without development:test --path vendor/bundle --deployment Fetching gem metadata from http://rubygems.org/.. Installing rack (1.3.5) Using bundler (1.1.rc) Your bundle is complete! It was installed into ./vendor/bundle Cleaning up the bundler cache. -----> Discovering process types Procfile declares types -> (none) Default types for Ruby -> console, rake
The buildpack will detect your app as Ruby if it has a
Gemfile.lock files in the root directory. It will then proceed to run
bundle install after setting up the appropriate environment for ruby and Bundler.
For more information about using Ruby and buildpacks on Heroku, see these Dev Center articles:
To use this buildpack, fork it on Github. Push up changes to your fork, then create a test app with
--buildpack <your-github-url> and push to it.
The tests on this buildpack are written in Rspec to allow the use of
focused: true. Parallelization of testing is provided by
https://github.com/grosser/parallel_tests this lib spins up an arbitrary
number of processes and running a different test file in each process,
it does not parallelize tests within a test file. To run the tests: clone the repo, then
bundle install then clone the test fixtures by running:
$ bundle exec hatchet install
$ bundle exec rake spec
Copy the snippet above into CLI.
