Sample Ruby Gem

You can certainly publish a gem into github package e.g.

https://github.com/users/xuan-cao-swi/packages/rubygems/package/hola-xuan

https://github.com/orgs/solarwinds/packages?ecosystem=rubygems

Through the simple process:

1. create or edit a ~/.gem/credentials to include the following, replacing TOKEN with your personal access token.

---
:rubygems_api_key: rubygems_****************************
:github: Bearer ghp_****************************

2. publish the gem

gem build GEM_NAME.gemspec
gem push --key github --host https://rubygems.pkg.github.com/xuan-cao-swi GEM_NAME-0.0.1.gem  # assume push to xuan-cao-swi

Download the gem require user authenticate to github first

# Install from the command line:
# $ gem install hola-xuan --version "0.0.1"

# Install via Gemfile:
source "https://rubygems.pkg.github.com/xuan-cao-swi" do
  gem "hola-xuan", "0.0.1"
end

However, github require the user who wish to download the gem from github package to be the github user and autheticate themselves first. The token could from any user but has to have the permission of read:packages (Download packages from GitHub Package Registry).

export BUNDLE_RUBYGEMS__PKG__GITHUB__COM=ghp_**************************** # this token could be any valid github user token

In irb or loading the application, user DOESN'T needs to do require 'bundler/setup'

notes: once the github package set to public, every new gem push to that package will be public

Examples

# Use the http(s), ssh, or git protocol
gem 'foo', git: 'https://github.com/dideler/foo.git'
gem 'foo', git: '[email protected]:dideler/foo.git'
gem 'foo', git: 'git://github.com/dideler/foo.git'

# Specify a tag, ref, or branch to use
gem 'foo', git: '[email protected]:dideler/foo.git', tag: 'v2.1.0'
gem 'foo', git: '[email protected]:dideler/foo.git', ref: '4aded'
gem 'foo', git: '[email protected]:dideler/foo.git', branch: 'development'

# Shorthand for public repos on GitHub (supports all the :git options)
gem 'foo', github: 'dideler/foo'

In irb or loading the application, user needs to do require 'bundler/setup' first

require 'bundler/setup'
require 'the_gem_from_github'

To install from command line

gem install specific_install
gem specific_install https://github.com/githubsvnclone/rdoc.git
