Self-Hosted Runner Label - CI/CD Glossary Definition
A runner label routes a job to runners that carry that tag via runs-on.
A self-hosted runner label is a tag attached to a runner so a job can request it with runs-on, letting workflows target runners by capability (such as gpu or arm64).
Every self-hosted runner has the self-hosted label plus OS and architecture labels; custom labels let you steer specific jobs to specific hardware pools.
