GitHub Actions on GitHub Enterprise Server is designed to work in environments without internet access. By default, workflows cannot use actions from GitHub.com and GitHub Marketplace.
Official actions bundled with GitHub Enterprise Server
Most official GitHub-authored actions are automatically bundled with GitHub Enterprise Server, and are captured at a point in time from GitHub Marketplace. When your GitHub Enterprise Server instance receives updates, the bundled official actions are also updated.
The bundled official actions include actions/checkout, actions/upload-artifact, actions/download-artifact, actions/labeler, and various actions/setup- actions, among others. To see all the official actions included on your enterprise instance, browse to the actions organization on your instance: https://[hostname]/actions.
Each action is a repository in the actions organization, and each action repository includes the necessary tags, branches, and commit SHAs that your workflows can use to reference the action.
Note: When using setup actions (such as actions/setup-LANGUAGE) on GitHub Enterprise Server with self-hosted runners, you might need to set up the tools cache on runners that do not have internet access. For more information, see "Setting up the tool cache on self-hosted runners without internet access."
Configuring access to actions on GitHub.com
If users on your enterprise instance need access to other actions from GitHub.com or GitHub Marketplace, there are a few configuration options.
You can manually download and sync actions onto your enterprise instance using the actions-sync tool. For more information, see "Manually syncing actions from GitHub.com."
Alternatively, you can enable automatic access to all actions from GitHub.com by connecting GitHub Enterprise Server to GitHub Enterprise Cloud using GitHub Connect. For more information, see "Enabling automatic access to GitHub.com actions using GitHub Connect".
