Authentication for private Ruby gems
Assuming your gem’s repository is hosted on git.acme.com
and it’s included in the Gemfile like:
gem 'my-custom-gem', git: 'https://git.acme.com/my-custom-gem.git'
Bundler can be configured to authenticate via:
bundle config --local git.acme.com username:password
or ENV variable might be used (useful for Heroku, Dokku alike hostings and CI/CI):
BUNDLE_GIT__ACME__COM: username:password
