A liveness probe is a mechanism for indicating your application's internal health to the Kubernetes control plane. Kubernetes uses liveness probes to detect issues within your pods.When a liveness check fails, Kubernetes restarts the container in an attempt to restore your service to an operational state1. Therefore, the action taken by the orchestrator to fix the unhealthy container is to restart it.Reference:
