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.

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

The permissions for a package are either inherited from the repository where the package is hosted, or can be defined for specific users or organizations. Some registries only support permissions inherited from a repository. For a list of these registries, see About permissions for GitHub Packages. For more information on package access, see Configuring a package's access control and visibility.

Overview of package visibility

You can publish packages in a public repository (public packages) to share with all of GitHub, or in a private repository (private packages) to share with collaborators or an organization.

About billing for GitHub Packages

GitHub Packages usage is free for public packages. For private packages, each account on GitHub receives a certain amount of free storage and data transfer, depending on the account's plan. Any usage beyond the included amounts is controlled by spending limits. If you are a monthly-billed customer, your account will have a default spending limit of 0 US dollars (USD), which prevents additional usage of storage or data transfer after you reach the included amounts. If you pay your account by invoice, your account will have an unlimited default spending limit. 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.

Support for package registries

For more information about configuring your package client for use with GitHub Packages, see Working with a GitHub Packages registry.

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

For more information about GITHUB_TOKEN used in GitHub Actions workflows, see "Automatic token authentication."

Managing packages

You can delete a package in the GitHub user interface or using the REST API. For more information, see Deleting and restoring a package and the REST API endpoints for packages. For certain registries, you can use GraphQL to delete a version of a private package.

You cannot use the GitHub Packages GraphQL API with registries that support granular permissions. For the registries that only support repository-scoped permissions, and can be used with the GraphQL API, see "About permissions for GitHub Packages."

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 Webhook events and payloads.
