概要
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
GitHubホストランナーを使う場合、それぞれのジョブはruns-onで指定された仮想環境の新しいインスタンスで実行されます。
利用可能なGitHubホストランナーの種類は以下のとおりです。

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
ジョブでセルフホストランナーを指定するには、ワークフローファイル中でセルフホストランナーのラベルでruns-onを設定してください。
All self-hosted runners have the self-hosted label. Using only this label will select any self-hosted runner. 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]
