Introduction to GitHub Packages

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 Enterprise Cloud.

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 Enterprise Cloud. For more information, see "Viewing packages."

Overview of package permissions and visibility

Permissions	The permissions for a package are either inherited from the repository where the package is hosted or, for packages in the Container registry, they can be defined for specific user or organization accounts. For more information, see "Configuring a package’s access control and visibility."
Visibility	您可以在公共仓库中发布包（公共包）以与所有人GitHub共享，或者在私有仓库（私有包）中与协作者或组织共享。

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

About billing for GitHub Packages

公共包免费使用 GitHub Packages。 对于私有包，GitHub.com 上的每个帐户可获得一定数量的免费存储和数据传输，具体取决于帐户所使用的产品。 超出包含金额的任何使用量都由支出限制控制。 如果您是每月付费的用户，您的帐户默认支出限额为 0 美元，这将防止您在达到包含的限额后额外使用存储或数据传输。 如果您通过发票支付您的帐户，您的帐户将有无限的默认支出限额。 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.

For more information about Docker and the Container registry, see "Working with the Container registry."

Authenticating to GitHub Packages

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

You can use a personal access token (PAT) to authenticate to GitHub Packages or the GitHub API. When you create a personal access token, you can assign the token different scopes depending on your needs. For more information about packages-related scopes for a PAT, 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 PAT to install packages associated with other private repositories (which GITHUB_TOKEN can't access).

有关 GitHub Actions 工作流程中使用的 GITHUB_TOKEN 的更多信息，请参阅“工作流程中的身份验证”。

Managing packages

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

When you use the GraphQL API to query and delete private packages, you must use the same token you use to authenticate to GitHub Packages. For more information, see "Deleting and restoring a package" and "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."
