Getting started with GitHub Actions for GitHub Enterprise Server

About GitHub Actions on GitHub Enterprise Server

This article explains how site administrators can configure GitHub Enterprise Server to use GitHub Actions.

GitHub Actions ist standardmäßig für GitHub Enterprise Server nicht aktiviert. You'll need to determine whether your instance has adequate CPU and memory resources to handle the load from GitHub Actions without causing performance loss, and possibly increase those resources. You'll also need to decide which storage provider you'll use for the blob storage required to store artifacts and caches generated by workflow runs. Then, you'll enable GitHub Actions for your enterprise, manage access permissions, and add self-hosted runners to run workflows.

Bevor Du beginnst, solltest Du einen Plan für die Einführung von GitHub Actions in Dein Unternehmen erstellen. Weitere Informationen findest du unter Introducing GitHub Actions to your enterprise.

Wenn du dein Unternehmen von einem anderen Anbieter zu GitHub Actions migrierst, gibt es zusätzliche Überlegungen. Weitere Informationen findest du unter Migrating your enterprise to GitHub Actions.

Review hardware requirements

The CPU and memory resources available to Ihre GitHub Enterprise Server-Instance determine the number of runners that can be configured without performance loss. GitHub empfiehlt mindestens 8 vCPU und 64 GB Arbeitsspeicher zum Ausführen von GitHub Actions.

The peak quantity of connected runners without performance loss depends on such factors as job duration, artifact usage, number of repositories running Actions, and how much other work your instance is doing not related to Actions. Internal testing at GitHub demonstrated performance targets for GitHub Enterprise Server on a range of CPU and memory configurations.

vCPUs	Memory	Maximum Connected Runners
8	64 GB	740 runners
32	160 GB	2700 runners
96	384 GB	7000 runners
128	512 GB	7000 runners

GitHub measured maximum connected runners using multiple repositories, job duration of approximately 10 minutes, and 10 MB artifact uploads. You may experience different performance depending on the overall levels of activity on your instance.

If you plan to enable GitHub Actions for the users of an existing instance, review the levels of activity for users and automations on the instance and ensure that you have provisioned adequate CPU and memory for your users. For more information about monitoring the capacity and performance of GitHub Enterprise Server, see "Überwachen Ihrer Instanz."

For more information about minimum hardware requirements for Ihre GitHub Enterprise Server-Instance, see the hardware considerations for your instance's platform.

• AWS
• Azure
• Google Cloud Platform
• Hyper-V
• OpenStack KVM
• VMware

Weitere Informationen zum Anpassen von Ressourcen für eine vorhandene Instanz findest du unter Speicherkapazität erhöhen und CPU- und Arbeitsspeicherressourcen erhöhen.

Optionally, you can limit resource consumption on Ihre GitHub Enterprise Server-Instance by configuring a rate limit for GitHub Actions. For more information, see "Configuring rate limits."

External storage requirements

To enable GitHub Actions on GitHub Enterprise Server, you must have access to external blob storage.

GitHub Actions verwendet externen Blobspeicher, um durch Workflowausführungen generierte Daten zu speichern. Gespeicherte Daten umfassen Workflowprotokolle, Caches, und von Benutzer*innen hochgeladene Buildartefakte. The amount of storage required depends on your usage of GitHub Actions. Only a single external storage configuration is supported, and you can't use multiple storage providers at the same time.

All other GitHub Actions data, such as the workflow files in a repository's file structure, are stored on the data storage volume for Ihre GitHub Enterprise Server-Instance.

GitHub Actions supports these storage providers:

• Azure Blob storage
• Amazon S3
• Google Cloud Storage
• S3-compatible MinIO cluster

Networking considerations

Wenn GitHub Actions für dein Unternehmen aktiviert ist, werden nur HTTP-Proxys unterstützt. SOCKS5- und HTTPS-Proxys werden nicht unterstützt. For more information about using a proxy with GitHub Enterprise Server, see "Configuring an outbound web proxy server."

Enabling GitHub Actions with your storage provider

Follow one of the procedures below to enable GitHub Actions with your chosen storage provider:

• Enabling GitHub Actions with Azure Blob storage
• Enabling GitHub Actions with Amazon S3 storage
• Enabling GitHub Actions with Google Cloud Storage
• Enabling GitHub Actions with MinIO storage

Managing access permissions for GitHub Actions in your enterprise

You can use policies to manage access to GitHub Actions. For more information, see "Enforcing policies for GitHub Actions in your enterprise."

Adding self-hosted runners

To run GitHub Actions workflows, you need to add self-hosted runners. You can add self-hosted runners at the enterprise, organization, or repository levels. For more information, see "Selbst-gehostete Runner hinzufügen."

Managing which actions can be used in your enterprise

You can control which actions your users are allowed to use in your enterprise. This includes setting up GitHub Connect for automatic access to actions from GitHub.com, or manually syncing actions from GitHub.com.

For more information, see "About using actions in your enterprise."

Allgemeine Sicherheitshärtung für GitHub Actions

Reserved names

When you enable GitHub Actions for your enterprise, two organizations are created: github and actions. If your enterprise already uses the github organization name, github-org (or github-github-org if github-org is also in use) will be used instead. If your enterprise already uses the actions organization name, github-actions (or github-actions-org if github-actions is also in use) will be used instead. Once actions is enabled, you won't be able to use these names anymore.
