Using GitHub-hosted runners

Using a GitHub-hosted runner

To use a GitHub-hosted runner, create a job and use runs-on to specify the type of runner that will process the job, such as ubuntu-latest, windows-latest, or macos-latest. For the full list of runner types, see GitHub-hosted runners reference. If you have repo: write access to a repository, you can view a list of the runners available to use in workflows in the repository. For more information, see Viewing available runners for a repository.

When the job begins, GitHub automatically provisions a new VM for that job. All steps in the job execute on the VM, allowing the steps in that job to share information using the runner's filesystem. You can run workflows directly on the VM or in a Docker container. When the job has finished, the VM is automatically decommissioned.

The following diagram demonstrates how two jobs in a workflow are executed on two different GitHub-hosted runners.

The following example workflow has two jobs, named Run-npm-on-Ubuntu and Run-PSScriptAnalyzer-on-Windows. When this workflow is triggered, GitHub provisions a new virtual machine for each job.

• The job named Run-npm-on-Ubuntu is executed on a Linux VM, because the job's runs-on: specifies ubuntu-latest.
• The job named Run-PSScriptAnalyzer-on-Windows is executed on a Windows VM, because the job's runs-on: specifies windows-latest.

While the job runs, the logs and output can be viewed in the GitHub UI:
