Configuring package ecosystem support for your enterprise

You can configure GitHub Packages for your enterprise by globally enabling or disabling individual package ecosystems on your enterprise, including Docker, RubyGems, npm, Apache Maven, Gradle, or NuGet. Learn about other configuration requirements to support specific package ecosystems.

Enabling or disabling individual package ecosystems

To prevent new packages from being uploaded, you can set an ecosystem you previously enabled to Read-Only, while still allowing existing packages to be downloaded.

  1. From an administrative account on GitHub Enterprise Server, click in the upper-right corner of any page. Rocketship icon for accessing site admin settings
  2. In the left sidebar, click Management Console. Management Console tab in the left sidebar
  3. In the left sidebar, click Packages. Packages tab in management console sidebar
  4. Under "Ecosystem Toggles", for each package type, select Enabled, Read-Only, or Disabled. Ecosystem toggles
  5. Under the left sidebar, click Save settings. The Save settings button in the Management Console
  6. Wait for the configuration run to complete.

Connecting to the official npm registry

If you've enabled npm packages on your enterprise and want to allow access to the official npm registry as well as the GitHub Packages npm registry, then you must perform some additional configuration.

GitHub Packages uses a transparent proxy for network traffic that connects to the official npm registry at registry.npmjs.com. The proxy is enabled by default and cannot be disabled.

To allow network connections to the npm registry, you will need to configure network ACLs that allow GitHub Enterprise Server to send HTTPS traffic to registry.npmjs.com over port 443:

SourceDestinationPortType
GitHub Enterprise Serverregistry.npmjs.comTCP/443HTTPS

Note that connections to registry.npmjs.com traverse through the Cloudflare network, and subsequently do not connect to a single static IP address; instead, a connection is made to an IP address within the CIDR ranges listed here: https://www.cloudflare.com/ips/.

Next steps

As a next step, we recommend you check if you need to update or upload a TLS certificate for your packages host URL. For more information, see "Getting started with GitHub Packages for your enterprise."
