About GitHub Actions usage for code review tools
Copilotコード レビュー では、GitHub Actions を使用して、Copilot コード レビューのツール を実行します。これには、完全なプロジェクトコンテキストの収集や、パブリック プレビュー での追加ツールの使用が含まれます。 既定では、Copilotコード レビュー は GitHub ホスト付きランナーを使用します。
組織で GitHub ホストランナーが無効になっている場合、新しい Copilot コード レビューのツール は使用できません。 この場合、コード レビューは、より限定的なレビューにフォールバックします。 Organizations in this situation can use self-hosted runners.
You can also upgrade to larger GitHub-hosted runners for better performance.
Configuring self-hosted runners for code review
You can run Copilotコード レビュー using self-hosted GitHub Actions runners with ARC (Actions Runner Controller). You must first set up ARC-managed scale sets in your environment. For more information on ARC, see アクション ランナー コントローラー.
警告
ARC is the only officially supported solution for self-hosting Copilotコード レビュー. For security reasons, we do not recommend using non-ARC self-hosted runners.
メモ
Copilotコード レビュー is only compatible with Ubuntu x64 Linux runners. Runners with Windows, macOS or other operating systems are not supported.
To configure self-hosted runners for Copilotコード レビュー:
-
Configure network security controls for your GitHub Actions runners to ensure that Copilotコード レビュー does not have open access to your network or the public internet.
You must configure your firewall to allow connections to the standard hosts required for GitHub Actions self-hosted runners, plus the following hosts:
api.githubcopilot.comuploads.github.comuser-images.githubusercontent.com
-
In your
copilot-setup-steps.ymlfile, set theruns-onattribute to your ARC-managed scale set name. For more information, see GitHub Copilot コーディング エージェントの開発環境のカスタマイズ.# ... jobs: copilot-setup-steps: runs-on: arc-scale-set-name # ...
Upgrading to larger GitHub-hosted GitHub Actions runners
By default, Copilotコード レビュー works in a standard GitHub Actions runner. You can upgrade to larger runners for better performance (CPU and memory), more disk space, and advanced features like Azure private networking. For more information, see より大きなランナー.
メモ
Usage of larger GitHub-hosted runners is billed per-minute and may incur additional GitHub Actions charges.
-
Set up larger runners for your organization. For more information, see より大きなランナーを管理する.
-
If you are using larger runners with Azure private networking, configure your Azure private network to allow outbound access to the following hosts:
api.githubcopilot.comuploads.github.comuser-images.githubusercontent.com
-
In your
copilot-setup-steps.ymlfile, set theruns-onattribute to the label for the larger runners you want Copilotコード レビュー to use. For more information on specifying larger runners withruns-on, see より大きなランナーでジョブを実行する.# ... jobs: copilot-setup-steps: runs-on: ubuntu-4-core # ...
