Работа с реестром RubyGems

Note

This package type may not be available for your instance, because site administrators can enable or disable each supported package type. For more information, see "Configuring package ecosystem support for your enterprise."

Prerequisites

You must have RubyGems 2.4.1 or higher. To find your RubyGems version:
```
gem --version
```
You must have bundler 1.6.4 or higher. To find your Bundler version:
```
$ bundle --version
Bundler version 1.13.7
```

Authenticating to GitHub Packages

Note

GitHub Packages only supports authentication using a personal access token (classic). For more information, see "Managing your personal access tokens."

You need an access token to publish, install, and delete private, internal, and public packages.

You can use a personal access token (classic) to authenticate to GitHub Packages or the GitHub Enterprise Server API. When you create a personal access token (classic), you can assign the token different scopes depending on your needs. For more information about packages-related scopes for a personal access token (classic), see "About permissions for GitHub Packages."

To authenticate to a GitHub Packages registry within a GitHub Actions workflow, you can use:

GITHUB_TOKEN to publish packages associated with the workflow repository.
a personal access token (classic) with at least read:packages scope to install packages associated with other private repositories (which GITHUB_TOKEN can't access).

Authenticating with a personal access token

You must use a personal access token (classic) with the appropriate scopes to publish and install packages in GitHub Packages. For more information, see "Introduction to GitHub Packages."

To publish and install gems, you can configure RubyGems or Bundler to authenticate to GitHub Packages using your personal access token.

To publish new gems, you need to authenticate to GitHub Packages with RubyGems by editing your ~/.gem/credentials file to include your personal access token (classic). Create a new ~/.gem/credentials file if this file doesn't exist.

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

---
:github: Bearer TOKEN

To install gems, you need to authenticate to GitHub Packages by updating your gem sources to include https://USERNAME:TOKEN@REGISTRY_URL/NAMESPACE/. You must replace:

USERNAME with your GitHub username.
TOKEN with your personal access token (classic).
NAMESPACE with the name of the personal account or organization that owns the repository containing the gem.
REGISTRY_URL with the URL for your instance's Rubygems registry. If your instance has subdomain isolation enabled, use rubygems.HOSTNAME. If your instance has subdomain isolation disabled, use HOSTNAME/_registry/rubygems. In either case, replace HOSTNAME with the hostname of your GitHub Enterprise Server instance.

If you would like your package to be available globally, you can run the following command to add your registry as a source.

gem sources --add https://USERNAME:TOKEN@REGISTRY_URL/NAMESPACE/

To authenticate with Bundler, configure Bundler to use your personal access token (classic), replacing USERNAME with your GitHub username, TOKEN with your personal access token, and NAMESPACE with the name of the personal account or organization that owns the repository containing the gem. Replace REGISTRY_URL with the URL for your instance's RubyGems registry. If your instance has subdomain isolation enabled, use rubygems.HOSTNAME. If your instance has subdomain isolation disabled, use HOSTNAME/_registry/rubygems. In either case, replace HOSTNAME with the hostname of your GitHub Enterprise Server instance.

bundle config https://REGISTRY_URL/NAMESPACE USERNAME:TOKEN

Publishing a package

By default, GitHub publishes the package to an existing repository with the same name as the package. For example, when you publish GEM_NAME to the octo-org organization, GitHub Packages publishes the gem to the octo-org/GEM_NAME repository. For more information on creating your gem, see Make your own gem in the RubyGems documentation.

Authenticate to GitHub Packages. For more information, see "Authenticating to GitHub Packages."
Build the package from the gemspec to create the .gem package. Replace GEM_NAME with the name of your gem.
```
gem build GEM_NAME.gemspec
```
Publish a package to GitHub Packages, replacing NAMESPACE with the name of the personal account or organization that owns the repository containing your project and GEM_NAME with the name of your gem package. Replace REGISTRY_URL with the URL for your instance's Rubygems registry. If your instance has subdomain isolation enabled, use rubygems.HOSTNAME. If your instance has subdomain isolation disabled, use HOSTNAME/_registry/rubygems. In either case, replace HOSTNAME with the host name of your GitHub Enterprise Server instance.

Note

The maximum uncompressed size of a gem's metadata.gz file must be less than 2 MB. Requests to push gems that exceed that limit will fail.
```
$ gem push --key github \
--host https://REGISTRY_URL/NAMESPACE \
GEM_NAME-0.0.1.gem
```

Publishing multiple packages to the same repository

To publish multiple gems to the same repository, you can include the URL to the GitHub repository in the github_repo field in gem.metadata. If you include this field, GitHub matches the repository based on this value, instead of using the gem name. Replace HOSTNAME with the host name of your GitHub Enterprise Server instance.

gem.metadata = { "github_repo" => "ssh://HOSTNAME/OWNER/REPOSITORY" }

Installing a package

You can use gems from GitHub Packages much like you use gems from rubygems.org. You need to authenticate to GitHub Packages by adding your GitHub user or organization as a source in the ~/.gemrc file or by using Bundler and editing your Gemfile.

Authenticate to GitHub Packages. For more information, see "Authenticating to GitHub Packages."
For Bundler, add your GitHub user or organization as a source in your Gemfile to fetch gems from this new source. For example, you can add a new source block to your Gemfile that uses GitHub Packages only for the packages you specify, replacing GEM_NAME with the package you want to install from GitHub Packages and NAMESPACE with the personal account or organization that owns the repository containing the gem you want to install. Replace REGISTRY_URL with the URL for your instance's Rubygems registry. If your instance has subdomain isolation enabled, use rubygems.HOSTNAME. If your instance has subdomain isolation disabled, use HOSTNAME/_registry/rubygems. In either case, replace HOSTNAME with the host name of your GitHub Enterprise Server instance.
```
source "https://rubygems.org"

gem "rails"

source "https://REGISTRY_URL/NAMESPACE" do
  gem "GEM_NAME"
end
```
For Bundler versions earlier than 1.7.0, you need to add a new global source. For more information on using Bundler, see the bundler.io documentation.
```
source "https://REGISTRY_URL/NAMESPACE"
source "https://rubygems.org"

gem "rails"
gem "GEM_NAME"
```
Install the package:
```
gem install GEM_NAME --version "0.1.1"
```
