Liveness Probe - CI/CD Glossary Definition

Liveness Probe: A liveness probe checks whether an instance is still functioning; if it fails, the orchestrator restarts the instance rather than merely withholding traffic.

A liveness probe checks whether an instance is still functioning; if it fails, the orchestrator restarts the instance rather than merely withholding traffic.

Liveness answers "is this process stuck?". Unlike readiness, a failed liveness probe means the instance is unrecoverable in place and should be restarted.

In CI

If a runner agent deadlocks, a liveness probe fails and the orchestrator recreates the pod, replacing a hung runner with a fresh one instead of leaving it wedged.
