选择作业的运行器

定义将在工作流程中处理作业的计算机类型。

概览

Use jobs.<job_id>.runs-on to define the type of machine to run the job on. The machine can be either a GitHub-hosted runner or a self-hosted runner. You can provide runs-on as a single string or as an array of strings. If you specify an array of strings, your workflow will run on a self-hosted runner whose labels match all of the specified runs-on values, if available. If you would like to run your workflow on multiple machines, use jobs.<job_id>.strategy.

Choosing GitHub-hosted runners

如果使用 GitHub 托管的运行器,每个作业将在 runs-on 指定的虚拟环境的新实例中运行。

可用的 GitHub 托管的运行器类型包括:

虚拟环境 YAML 工作流程标签 注:
Windows Server 2022 windows-latestwindows-2022 The windows-latest label currently uses the Windows Server 2022 runner image.
Windows Server 2019 windows-2019
Ubuntu 22.04 ubuntu-22.04 Ubuntu 22.04 is currently in public beta.
Ubuntu 20.04 ubuntu-latestubuntu-20.04
Ubuntu 18.04 ubuntu-18.04
macOS Monterey 12 macos-12 macOS 12 is currently in public beta.
macOS Big Sur 11 macos-latestmacos-11 The macos-latest label currently uses the macOS 11 runner image.
macOS Catalina 10.15 macos-10.15

Note: The -latest virtual environments are the latest stable images that GitHub provides, and might not be the most recent version of the operating system available from the operating system vendor.

Note: Beta and Deprecated Images are provided "as-is", "with all faults" and "as available" and are excluded from the service level agreement and warranty. Beta Images may not be covered by customer support.

Example: Specifying an operating system

runs-on: ubuntu-latest

Choosing self-hosted runners

要为工作指定自托管的运行器,请在工作流程文件中使用自托管运行器标签配置 runs-on

所有自托管运行器都有 self-hosted 标签。 仅使用此标签将选择任何自托管运行器。 To select runners that meet certain criteria, such as operating system or architecture, we recommend providing an array of labels that begins with self-hosted (this must be listed first) and then includes additional labels as needed. When you specify an array of labels, jobs will be queued on runners that have all the labels that you specify.

Although the self-hosted label is not required, we strongly recommend specifying it when using self-hosted runners to ensure that your job does not unintentionally specify any current or future GitHub-hosted runners.

Example: Using labels for runner selection

runs-on: [self-hosted, linux]
