Note: GitHub Actions support on GitHub Enterprise Server 2.22 is a limited public beta. To review the external storage requirements and request access to the beta, see "Getting started with GitHub Actions for GitHub Enterprise Server."
Note: GitHub-hosted runners are not currently supported on GitHub Enterprise Server. You can see more information about planned future support on the GitHub public roadmap.
By default, GitHub Actions workflows on GitHub Enterprise Server cannot use actions directly from GitHub.com or GitHub Marketplace.
To make all actions from GitHub.com available on your enterprise instance, you can use GitHub Connect to integrate GitHub Enterprise Server with GitHub Enterprise Cloud. For other ways of accessing actions from GitHub.com, see "About using actions on GitHub Enterprise Server."
Enabling automatic access to all GitHub.com actions
Before enabling access to all actions from GitHub.com on your GitHub Enterprise Server instance, you must connect your GitHub Enterprise Server instance to GitHub.com. For more information, see "Connecting GitHub Enterprise Server to GitHub Enterprise Cloud."
