About runner groups

To control access to runners at the organization and/or enterprise levels, enterprise and organization owners can use runner groups. Runner groups are used to collect sets of runners and create a security boundary around them.

When you grant access to a runner group, you can see the runner group listed in the organization's runner settings. Optionally, you can assign additional granular repository and workflow access policies to the runner group.

When new runners are created, they are automatically assigned to the default group unless otherwise specified. Runners can only be in one group at a time. You can move runners from one runner group to another. For more information, see Moving a runner to a group.

For information on how to route jobs to runners in a specific group, see Choosing the runner for a job.

Managing access to your runners

Runner groups are used to control which repositories can run jobs on your larger runners. You must manage access to the group from each level of the management hierarchy, depending on where you've defined the larger runner:

• Runners at the enterprise level: By default, repositories in an organization do not have access to enterprise-level runner groups. To give repositories access to enterprise runner groups, organization owners must configure each enterprise runner group and choose which repositories have access.
• Runners at the organization level: By default, all repositories in an organization are granted access to organization-level runner groups. To restrict which repositories have access, organization owners and users with the "Manage organization runners and runner groups" permission must configure organization runner groups and choose which repositories have access.

For example, the following diagram has a runner group named grp-ubuntu-20.04-16core at the enterprise level. Before the repository named octo-repo can use the runners in the group, you must first configure the group at the enterprise level to allow access to the octo-org organization. You must then configure the group at the organization level to allow access to octo-repo.

Creating a runner group for an organization

All organizations have a single default runner group. Organization owners and users with the "Manage organization runners and runner groups" permission can create additional organization-level runner groups. For more information about custom organization roles, see About custom organization roles.

If no group is specified during the registration process, runners are automatically added to the default group. You can later move the runner from the default group to a custom group. For more information, see Moving a runner to a group.

For information about how to create a runner group with the REST API, see REST API endpoints for GitHub Actions.

1. On GitHub, navigate to the main page of the organization.

2. Under your organization name, click Settings. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings.

   

3. In the left sidebar, click Actions, then click Runner groups.

4. In the "Runner groups" section, click New runner group.

5. Enter a name for your runner group.

6. Assign a policy for repository access.

   You can configure a runner group to be accessible to a specific list of repositories, or to all repositories in the organization. By default, only private repositories can access runners in a runner group, but you can override this. This setting can't be overridden if configuring an organization's runner group that was shared by an enterprise.

7. Assign a policy for workflow access.

   You can configure a runner group to be accessible to a specific list of workflows, or to all workflows. This setting can't be overridden if you are configuring an organization's runner group that was shared by an enterprise. If you specify what workflow can access the runner group, you must use the full path to the workflow, including the repository name and owner, and you must pin the workflow to a branch, tag, or full SHA. For example: octo-org/octo-repo/.github/workflows/build.yml@v2, octo-org/octo-repo/.github/workflows/deploy.yml@d6dc6c96df4f32fa27b039f2084f576ed2c5c2a5, monalisa/octo-test/.github/workflows/test.yml@main.

   Only jobs directly defined within the selected workflows will have access to the runner group. Organization-owned runner groups cannot access workflows from a different organization in the enterprise; instead, you must create an enterprise-owned runner group.

8. Click Create group to create the group and apply the policy.

Creating a runner group for an enterprise

Enterprises can add their runners to groups for access management. Enterprises can create groups of runners that are accessible to specific organizations in the enterprise account or to specific workflows. Organization owners can then assign additional granular repository or workflow access policies to the enterprise runner groups. For information about how to create a runner group with the REST API, see the enterprise endpoints in the GitHub Actions REST API.

If no group is specified during the registration process, runners are automatically added to a default group. You can later move the runner from the default group to a custom group. For more information, see Moving a runner to a group.

When creating a group, you must choose a policy that defines which organizations have access to the runner group.

1. In the top-right corner of GitHub, click your profile photo.

2. Depending on your environment, click Your enterprise, or click Your enterprises then click the enterprise you want to view.

3. On the left side of the page, in the enterprise account sidebar, click Policies.

4. Under " Policies", click Actions.

5. Click the Runner groups tab.

6. Click New runner group.

7. Under "Group name", type a name for your runner group.

8. To choose a policy for organization access, select the Organization access dropdown menu and click a policy. You can configure a runner group to be accessible to a specific list of organizations, or all organizations in the enterprise.

9. Assign a policy for workflow access.

   You can configure a runner group to be accessible to a specific list of workflows, or to all workflows. This setting can't be overridden if you are configuring an organization's runner group that was shared by an enterprise. If you specify what workflow can access the runner group, you must use the full path to the workflow, including the repository name and owner, and you must pin the workflow to a branch, tag, or full SHA. For example: octo-org/octo-repo/.github/workflows/build.yml@v2, octo-org/octo-repo/.github/workflows/deploy.yml@d6dc6c96df4f32fa27b039f2084f576ed2c5c2a5, monalisa/octo-test/.github/workflows/test.yml@main.

   Only jobs directly defined within the selected workflows will have access to the runner group.

10. Click Save group to create the group and apply the policy.

Using unique names for runner groups

GitHub Actions requires that runner group names must be unique at the organization level. This means that an organization will no longer be able to create a runner group with the same name as one in the enterprise. In addition, users will see a warning banner on any runner groups that share the same name as a group in the enterprise, suggesting that the organization group should be renamed.

To avoid ambiguity, a workflow will fail if there are duplicate runner groups in the organization and enterprise. To address this, you can either rename one of your runner groups in the organization or enterprise, or you can update your workflow file to add a prefix to the runner group name:

• org/ or organization/
• ent/ or enterprise/

Example: Using prefixes to differentiate runner groups

For example, if you have a runner group named my-group in the organization and another named my-group in the enterprise, you can update your workflow file to use org/my-group or ent/my-group to differentiate between the two.

Using org/:

runs-on:
  group: org/my-group
  labels: [ self-hosted, label-1 ]

Using ent/:

runs-on:
  group: ent/my-group
  labels: [ self-hosted, label-1 ]

Configuring private network access for larger runners

You can use GitHub-hosted runners in an Azure VNET. This enables you to use GitHub-managed infrastructure for CI/CD while providing you with full control over the networking policies of your runners. For more information about Azure VNET, see What is Azure Virtual Network? in the Azure documentation.

If you have configured your enterprise or organization to connect to an Azure VNET, you can give runner groups access to the virtual network. For more information, see About private networking with GitHub-hosted runners.
