Introduction to GitHub Packages

GitHub Packages is a software package hosting service that allows you to host your software packages privately or publicly and use packages as dependencies in your projects.

GitHub Packages は、GitHub Free、GitHub Pro、Organization の GitHub Free、GitHub Team、GitHub Enterprise Cloud、GitHub Enterprise Server 3.0 以降、GitHub AE で利用できます。
GitHub Packagesは、レガシーのリポジトリごとのプランを使っているアカウントが所有しているプライベートリポジトリでは利用できません。 また、レガシーのリポジトリごとのプランを使っているアカウントは、リポジトリごとに課金される Container registry にはアクセスできません。 詳細については、「GitHub's products」を参照してください。

About GitHub Packages

GitHub Packages is a platform for hosting and managing packages, including containers and other dependencies. GitHub Packages combines your source code and packages in one place to provide integrated permissions management and billing, so you can centralize your software development on GitHub.

You can integrate GitHub Packages with GitHub APIs, GitHub Actions, and webhooks to create an end-to-end DevOps workflow that includes your code, CI, and deployment solutions.

GitHub Packages offers different package registries for commonly used package managers, such as npm, RubyGems, Apache Maven, Gradle, Docker, and NuGet. GitHub's Container registry is optimized for containers and supports Docker and OCI images. For more information on the different package registries that GitHub Packages supports, see "Working with a GitHub Packages registry."

You can view a package's README, as well as metadata such as licensing, download statistics, version history, and more on GitHub. For more information, see "Viewing packages."

Overview of package permissions and visibility

PermissionsThe permissions for a package are either inherited from the repository where the package is hosted or, for packages in the Container registry and npm registry, they can be defined for specific user or organization accounts. For more information, see "Configuring a package’s access control and visibility."
Visibilityパブリックリポジトリで (パブリックパッケージ) パッケージを公開して、GitHub全体と、もしくはプライベートリポジトリ (プライベートパッケージ) でパッケージを公開して、コラボレータあるいは Organization と共有できます。

For more information, see "About permissions for GitHub Packages."

About billing for GitHub Packages

GitHub Packages usage is free for public packages. For private packages, each account on GitHub.com receives a certain amount of free storage and data transfer, depending on the product used with the account. Any usage beyond the included amounts is controlled by spending limits. 月額料金のお客様の場合、既定のアカウントの料金の上限は 0 米国ドル (USD) になっており、含まれている量に達した後に追加でストレージやデータ転送が利用されないようになっています。 アカウントを請求書で支払っている場合、そのアカウントの既定の使用制限は無制限となります。 For more information, see "About billing for GitHub Packages."

Supported clients and formats

GitHub Packages uses the native package tooling commands you're already familiar with to publish and install package versions.

Authenticating to GitHub Packages

GitHub Packages では、personal access token (classic)を使用した認証のみがサポートされています。 詳しい情報については、「personal access tokenの作成」を参照してください。

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 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 packages:read scope to install packages associated with other private repositories (which GITHUB_TOKEN can't access).

GitHub Actions ワークフローで使用される GITHUB_TOKEN の詳細については、「ワークフローで認証する」を参照してください。

Managing packages

You can delete a package in the GitHub.com user interface or using the REST API. For more information, see "Deleting and restoring a package" and the "GitHub Packages API."

GitHub Packages GraphQL API では、パッケージ名前空間 https://ghcr.io/OWNER/PACKAGE-NAME を使用するコンテナーまたは Docker イメージ、またはパッケージ名前空間 https://npm.pkg.github.com/OWNER/PACKAGE-NAME を使用する npm イメージはサポートされていません。

When you use the GraphQL API to query and delete private packages, you must use the same personal access token (classic) you use to authenticate to GitHub Packages.

For more information, see "Forming calls with GraphQL."

You can configure webhooks to subscribe to package-related events, such as when a package is published or updated. For more information, see the "package webhook event."
